Battizer Alkaline Battery Charger Review

When I first got to know about Battizer Alkaline Battery Charger, I was actually not very convinced. The features of the charger is too good to be true. An hour charge for Alkaline, Rechargeable, Zinc Carbon, Zinc Chloride batteries. And you can charge for both sizes, AA or AAA.

As I am a heavy user of rechargeable batteries, I thought it might do justice to the price tag of S$97. So, I ordered online and within a few days, it came to my doorsteps. Honestly, I am quite surprised by the packaging. Although the paper box is quite filmsy, Battizer actually uses a clear plastic case to hold them. It looks nice too.

And here is the back view.

Now, take a look inside.

In the package, you get one Battizer Alkaline Charger with a 2-plug cable, 4 Battizer AA Alkaline Batteries and a CD Manual. I don’t think you need to use the manual to operate this Charger ๐Ÿ™‚ .

Take a look at the back of the unit.

A close up of the information stated.

As you can see, the output current is not high. That may be the reason why the unit is not hot. However, I must say that to be able to charge a battery in one hour without the heat is a feat. I have tried many chargers. Most of them will cause the batteries to heat up. I checked on one of my chargers. It stated 1000mAh output current.

BTW, I think the cable provided is too short. You have to be very near to a socket to use the charger. Not a big issue as this is NOT a special cable. You can replace it with a longer one. I have also talked to Alvin from Battizer about it. He mentioned he will feedback to his company.

Anyway, I tested the unit in two scenarios:

  • An average user who use it to charge normal alkaline batteries for remote controllers, torch light and etc.
  • A demanding photographer will need the speed and juice of the batteries to the Flash unit to take pictures.

BTW, here are some of the batteries that I tested. On the left are alkaline and on the right are rechargeable batteries.

Scenario 1:

Charging all my controllers (TV, Starhub Cable, Aircon Units, Freshener, torchlights)

Battery types:

AA and AAA with mixture of brands.

Results:

At first try, only a few newer batteries can be charged completely (means LED light will stop blinking, see below picture)

I must say the first try is disappointing as some of them causes the LED to become RED. I thought they were hopeless. However, thanks to Alvin from Battizer, I realized that they can still be saved! According to Alvin, as long as the batteries do not turn RED immediately after you turn on the power, that means this battery can still be “saved”. You will need to let the battery “rest” and charge again. It is a reconditioning for the batteries. So I heeded his advice and recharge those with problem again.

True enough, some several tries, I managed to salvage most of the batteries. Some of them took them 7 to 8 times (almost 1/2 to 1 hour each) to complete the charging.

The results of the batteries are not bad. As mentioned, those controllers have very old batteries. After “reviving” them, it works perfectly. For torch light, initially, it totally cannot light up. After charging, it is able to work again.

So, the question is, “Will you spend so much time to recondition the old batteries so that you can use again?” I would for the sake of environment. Here is how Battizer calculate the cost.

4. What is the cost of recharging 4 pieces of AA batteries?

There are 4 channels in a Battizer charger and therefore you can charge 4 pieces of AA alkaline batteries at one time. Every channel has an output current of 250 mA with approximately 2 Volt. Working out to 250/1000 A * 2V * 4 channels = 2 Watt with efficiency approximately at 75% and so 2/0.75 = 2.66 Watt, and so in 1 hour = 2.66 Wh. Assuming that your electricity cost is 30 cents per kWh. It will cost you only: $0.30 * 2.66/1000 = $0.000798 to charge up 4 pieces of alkaline batteries comparing to $4 to buy a new set.
If you need to replace your discharged batteries, it will probably cost you $1 a piece for alkaline battery and $4 to have 4 pieces to be replaced.

However, do note that it can only be recharged for a certain cycle.

From their website,

5. How many times can I recharge an alkaline battery and how many times can I recharge a zinc-carbon battery?

With our record test, between 10 to 50 times for alkaline batteries and 5 to 10 times for zinc-carbon batteries. It all depends on how frequently you recharge immediately after use.

Not bad to recycle the batteries for 50 times. Here is my summary for Scenario 1

Summary for Scenario 1:

The Battizer does serve its purpose of charging Alkaline batteries in 1 hour (some a little bit longer) and based on normal usage, it looks good. In fact, I did a check on the multimeter for a 1.5V alkaline battery after recharging. It went up to 1.6++v for a battery that is supposed to be wasted.

However, do take note that old batteries are difficult to charge. Often, you may encounter the RED blinking LED. It is up to you to redo the process or just dispose off the batteries. I have better luck with Energizer batteries. They are easy to charge. However, do not charge those LITHIUM batteries. They are not supposed to be charge on this charger.

My suggestion for household with kids that need a lot of batteries for the toys, you may want to consider Battizer Alkaline Charger. I understand that some toys uses D type batteries. Battizer can only charge AA or AAA batteries. I think you can use a adapter to do the trick.

Overall, quite please with the charger for normal usage.

Scenario 2 (Partial Update):

Charging of rechargeable batteries for photographic equipments. It is a partial update as I have to run a few more tests and scenarios to really conclude.

Results:

I was toying around with the idea of charging the batteries for my camera flash unit with Battizer Alkaline Charger. My first try was a failure. I took 4 Powerex 2700 mAh batteries to charge on Battizer. After one hour, the indication is still blinking. However, based on the instruction, for rechargeable batteries, we can off the power after 1 hour. So, I did that and quickly put the batteries to the test.

I sense something is not right when I power on my Flash unit. It did not charge up immediately. Nevertheless, after it lighted up (the ready light), I fired one shot and the Flash went dead. Then I use my standard Konnoc Charger to check the battery condition, almost all of them were at low battery level.

Of course, to review Battizer, I did not give up easily. I tried on another set of Powerex 2700mAh batteries and this time, it is able to charge up properly. Knowing that I am taking a risk, I went for an event with these batteries. One set charged with Konnoc and another set charged with Battizer and also I used Battizer Alkaline batteries.

Battizer Alkaline Batteries: Charging up take a little longer but still useable. Don’t expect fantastic results for a high power flash.

Powerex charged with Battizer: Can perform but I have not tested enough to conclude. Seems a little bit lacking but it might be the environment and many factors.

Powerex charged with Konnoc: Performance is standard as compared to my previous shoots.

Summary:

As you can see, my results is as vague as ever. I do not want to conclude anything yet. I will need some more shoot and time to really understand the impact. Baseline is I do not want to jeopardize someone having issues on the batteries on important shoots.

I tried not to use too much technical terms in my review so that anyone can understand the pros and cons of Battizer Alkaline Charger. I hope you enjoy this review. Part 2 will be coming for Scenario 2. In the meanwhile, shoot as many questions as possible, I will get Battizer to answer them if I could not.

    Wait, you are recharging normal non-recharagable batteries? Is it safe? All those batteries have instructions that says not to recharge.

  • DK: Yes, normal alkaline batteries. The charger can handle it plus all those rechargeable batteries.

    Warning labels on batteries are for those who tried to charge using a normal charger, not with this type of charger.

  • William

    Seem like it is not the only product that claims the features advertised by Battizer.

    ReZap does the same and more.
    http://www.rezap.com.au/

    Care to compare rezap with battizer and let us (consumers) know which is a better product and value?

  • William: Yes, it seems the same. However, I found that the ReZap has a long charging time:

    1 to 8 hours for Alkaline Batteries
    1 to 16 hours for rechargeable batteries

    Whereas, the Battizer charges in 1 hour.

    Dear Sir,
    I purchase a Battizer model 11410B from BLISS Computer on 5/9/2010. I tried to charge 4 Energizer Batteries. The 4 green lights blink for 90 minutes. Is it normal too take that long. I noted on your product box, Full charge in sixty minutes.
    I tried to use your CD, but My computer hung. It cannot be switch off until I disconnect the computer battery. Is it normal or anything wrong with the CD. Please advice.

    Regards

  • Tan Hwee Kheng: Thanks for dropping by. Have you contacted the manufacturer about the CD?

    As for the charging time, my experience is around 1 hr ++ . First time may take a little longer. Why not you try to charge again to see.

  • Tommy

    I am having same problem. Is the Led supposed to be blinking or should stay on when charging?

  • Tommy: It will be blinking while charging and will stay on (stop blinking) once it is charged. BTW, I am talking about Alkaline batteries only. If you are charging rechargeable batteries, from their website, it will always blink (although in my case, it will stay on after more than 1 hour of charge).

  • Tommy

    Thanks for the reply. Reason I asked is because charging for alkaline seems to take long time. Not the 1 hour as stated. Probably will try again and see how long it takes for it to stop blinking.

  • Tommy

    Something is not right. It’s been charging for 4 hours and it’s still blinking!

  • Tommy: This is really strange. Hv u tried with other batteries?

  • Tommy

    So far tried energizer only

  • KC

    Hi,

    Has anyone else bought from Bliss Computer? How much did you pay for it?

  • Eric

    I bought a Battizer from Bliss Computer for $85. I tried a AAA panasonic alkaline that I used in my mp3 player until it died. I immediately get a blinking red light which I guess means it can’t be charged. This is the only battery I have had to try so far but I’m pretty disappointed.

  • Eric: I guess you will need to charge it before it dies (says their website). I have used AAA also for my controllers. So far, ok.

  • Eric

    Their website mentions devices that drain it completely like flashlights.
    My mp3 players dies before the battery is totally dead. I know because with rechargables, right after the mp3 player dies, if I try and turn it back on, it will run for a few seconds and then die again. So the battery shouldn’t have been completely dead when the mp3 player stopped.

    I did try that battery again after it ‘rested’. This time I got blinking green. After 1.5 hours it changed to slow blinking green (6 seconds / blink). It would help if they had a manual on their website. The mini CD that came with it my computer can’t read since it is a slot-load CD player not a tray. It has now been 3 hours and it is still a slow green blink, I guess I’ll check if it is charged. Still disappointed, the device does not at all perform as advertised.

  • Eric: I see. Hey, that’s good feedback. I did not encounter such issue except for a few super old alkaline batteries.

    Most of the time, I charge rechargeable batteries for my camera flash.

  • Eric

    Ok, when I tested that battery with the slow green blink it had charged even though the blinking never stopped.

    During all this the duracell alkaline in my mp3 player got down to zero battery bars but still playing, so I decided to stop and recharge it before it was totally dead. No deal, all I get is the blinking red light. I tried letting it ‘rest’ like the last one, and still nothing but a blinking red light.

  • The CD contain an ebook which will auto-run when you put it into the CD/DVD ROM drive. This CD is Windows compatible only. The anti-virus software in your computer may block it from running. Most of the instructions on using the charger is available on our website.

    We cannot claim that our charger can charge all alkaine, zinc carbon or zinc chloride batteries under all type of conditions. Claiming so will cause us to fall faster than a sky diver jumping out of the plane.

    When we developed our charger, we tested it with many brands of batteries and also tested other similar chargers. We also tested how different type of batteries performed in different devices and equipments. And we have some surprised discovery.

    First, batteries are of different quality, even for the same brand but are manufactured in different countries. Some brand of batteries are manufactured in a particular country and are meant to be sold in only that country. In order to make the batteries affordable to the people, manufacturer reduce the chemical and materials used to produce the battery so as to reduce the cost and retail price.

    When these batteries are exported out and sold in other countries where there are factory for the same brand of battery, consumers will think that these batteries are of the same quality as the locally produced batteries but they are not.

    To make the matters worse, there are fake or imitation batteries of poorer quality. Google for “fake brand battery”. Replace the word “brand” with the battery brand. And there are other brands unheard of.

    Better quality batteries are able to charge better by our charger and perform better after charge.

    Next, some devices and equipments can cause the alkaline or zinc chloride battery to become unchargeable by our charger. Low powered or low drained devices without voltage control can drain the batteries until very low voltage and our charger may not be able to charge them up.

    There are also different characteristics between disposable batteries (alkaline, zinc carbon and zinc chloride) and rechargeable batteries (NiMH and NiCad). For rechargeable batteries, you can drain them until very low voltage or very dry and still be able to charge them up.

    Before we developed our charger, most people will “squeeze the last drop” out of their disposable batteries to get our money’s worth. I remember that I used to use the drained batteries in my Walkman for my clock, TV remote controller or torchlight. But this will make the battery unchargeable by our charger.

    If the battery is left discharged or drained for a long time, our charger may not be able to charge them too.

    When we did our battery collection and reuse project, we managed to charge 60% of the batteries we collected. The rest were not chargeable due to factors mentioned above and others. We collected over 6000 pieces of used batteries and that mean a reduction of about 3600 batteries waste.

    To get the best performance out of our charger, use good quality batteries and don’t drain them till very low or totally flat before you charge them. We recommend that you charge them as often as you can.

    Another thing to note is that the speed of the light blinking does not mean anything.

  • Battizer: Thanks for the long reply. Hope that it clears some queries about the product. ๐Ÿ™‚

  • Eric

    Well for those who can’t read the e-book for some reason, it would be nice if they had it as a PDF file on your website.

    Battizer said:
    “Most of the instructions on using the charger is available on our website.”

    If that is so please provide a link. I’ve looked and the only ‘instructions’ are:
    “LED indicators monitor charging status โ€“ blinking green for charging & steady green for full charge”
    These is also a footnote to say the LEDs do not monitor rechargable batteries

    There is no mention of red LEDs or letting batteries ‘rest’ after the first charge attempt to try again later.

    I understand that totally draining the battery is bad, but you say:
    “We recommend that you charge them as often as you can.”
    while your website says:
    “Alkaline batteries may be charged up to 10 times or more.”
    So if I charge my batteries after they are only 25% used, and get 10 charges, that is a lot less use than if I get 10 charges of 90% used batteries.

    I appreciate that battizer responded here, but they didn’t really clear up any of my questions. Their long info about low quality and fake brand batteries I don’t think applies to the batteries I tried. The Panasonic is a reliable brand I bought at Cold Storage here in Singapore, not some discount street booth, and the Duracell I bought in the U.S. and I hadn’t even fully discharged it before trying to recharge. Stranger still even though the Duracell got the blinking red light, it does appear to be recharged since it now shows full charge in my mp3 player again.

    To be clear my questions are:
    1) What does the blinking red LED mean?
    2) When and why am I supposed to let a battery ‘rest’ before trying again to charge it?
    3) Why do my alkaline batteries never get the constant green LED for fully charged?

    My disappointment with Battizer is their site claims a simple ‘put drained batteries in charger for 1 hour and they will be fully charged’
    Clearly this is NOT true much of the time. No where on their web site does it say if you fully drain your battery it won’t charge, all they say is:
    “To achieve highest charging capacity, recharge drained batteries immediately.”
    Notice they use the word drained there themselves.
    Their description sounds too good to be true, and clearly is too good to be true and I am disappointed that I was taken in by it.

  • KC

    I bought the Bliss too but they insisted on adding GST on top of $85. I suppose I have been overcharged

    KC: I bought the unit at Bliss as well. I specifically asked the sales guy exactly how much it cost and he said $85. I took out $85 from my wallet. The guy printed an invoice and asked me for $90.95. i was like: WTF? The guy then said: oh, plus GST lah. Why can’t he just tell me it’s $91 as required by law??

  • A uncomplicated battery charger equivalent to a ACDC wall adapter. It applies 300mA for the battery at all times, which will harm the battery pack if left connected too extended.

    My experiences with the Battizer:

    Last week, I bought a unit from Carrefour.

    Using it for the first time, I tried to recharge 4 x GP Ultra Alkaline (those golden cylinder ones) AA batteries. I first bought these batteries about 6 months back to use on an MP3 recorder. The batteries were used to the point where they can’t supply enough power to the recorder for recording anymore. Since then, they lie unused for about 4 months.

    Before putting these 4 batteries to the battizer for charging, I wanted to somehow note their ‘before charging’ state, so that I can compare against the ‘after charging’ state. To get the ‘before’ state, I did only a rough gauge by putting a pair into the mp3 recorder and turning the device on. Immediately, the device showed “battery low” and shut down, as I had expected.

    I then proceeded to charge the batteries for about 1 hour 15 minutes. That whole time, the LEDs were green and blinking.

    After that time, I took out the batteries from the charger. They felt quite warm – it’s hard to give a good gauge of the temperature, but I would say it’s more than luke warm – a bit verging on hot, like a packet of fresh fries.

    I allowed the batteries to cool for about 10 minutes, then put a pair into the recorder to see how much charge has been “regained” by Battizer. The mp3 recorder’s battery gauge shows 100%, to my delight. I then tried recording for about 10 seconds. During this time, the gauge showed an anomaly whereby the gauge plunged for a split second to 1 bar (out of 4), then bounced right back up to 4 bars again. That seems a bit strange.

    I then allowed the batteries to rest overnight.

    The next day, I decided to charge the 4 batteries further, as I have read that the batteries are fully charged only when the LEDs are solid green. About 2 hr 15 min into the charging, I noticed that the LEDs have indeed stopped blinking (and they are green)! That looks like good news. Again, I tried out a pair of batteries on my recorder. This time, things seemed ok – no more battery gauge plunge/surging anomaly like yesterday.

    After trying out the newly-recharged alkalines for about 1 minute, I then took the batteries out of the recorder and put them on the table, and kind of forgot about them.

    About 3 hours later, I hear a sucking/hissing sound coming from my table. It sounds like frothy liquid/air bubbling through a small aperture. Curious, I went to check. The moment I reached the table, the hissing stopped. I thought it came from my handphone (static from spoiled speakers??!) and so pressed a few keys on the handphone to try things out. The pressing of the keys must have transmitted some small vibrations to the table, as it seems to have disturbed the source of ths hissing and the sound came back again. Lo and behold – it was then that I realised that one of the recharged batteries have leaked! I don’t feel it’s safe to leave that battery around, so I gingerly picked it up and threw it into the bin.

    So, I am wondering whether it’s really safe to recharge these alkalines. The leaking battery doesn’t seem old to me (no rust) – and in fact, I did a visual check for rust just before putting them into battizer. The battery’s metal casing also seems to be in pretty good shape. In all, it looks like new. I would have thought it would be “quite” safe to give this battery a recharge since it looks like a healthy-enough candidate. From my very very short tests (as you can see), the Battizer indeed seems to bring back the juice in old batteries. However, I am concerned about safety (won’t explode/leak, *Really*?) and whether a recharged battery will leak and damage my equipment. I would like to experiment a bit more, but with trepidation this time.

  • wow

    After seeing We’s account of experience, i decided to give it a pass. Not really worthed risking any electronic equipments over some possible savings/recycling of alkaline batteries imo.

    Hopefully such technology will improve & stabilize before i shall consider ultisling them

  • Eric

    I thought I should do one final followup on the battizer. I have been using it now for almost two months. Pretty much exclusively to charge the AAA batteries for my mp3 player. I’ve used lots of different brands. Here is my conclusion.

    1) I pretty much ignore the lights. The same battery will sometimes get a solid green light after an hour, or will blink red continuously. Either way after an hour they have some charge, and after discharged the next time you charge them what the lights do is unrelated to what they did before. If it never got solid green, and then you use it, it may well get solid green next time.

    No matter what the lights do, after an hour they usually show 3 bars in the mp3 player (mp3 battery display is 0-3 bars). A battery charged with the battizer never lasts as long as a new alkaline battery, even if it recharged back to 3 bars. Usually it lasts 1/4 to 1/2 as long as new.

    Sill alkaline are cheaper than rechargable, and (I hope) better for the environment. So I have to change the battery in my mp3 player more often, but it works. I don’t think I will ever recoup the cost of the charger, but I feel better that I am putting fewer toxic metals into the environment.

    Update on my previous report:

    To date, I have charged 8 GP Ultra-Alkaline batteries. Of the 8, 4 have since leaked. Details on the 4 that leaked:

    3 x leaked during non-usage (1 of which was the one reported in the earlier write-up).

    1 x leaked inside a wireless mouse, which was kept on 24/7. Thankfully it is just a mouse (albeit not a cheap one, boohoo), and not some expensive equipment.

    I’m not sure if my encounters are typical, but with a 50% failure rate, I am now more than apprehensive of using the battizer … Having chemicals seeping out anywhere, be it inside electronic equipment or onto any human-contactable surface, just isn’t a Good Thing.

    2 points I’ve been thinking about:

    I have seen that, indeed the battizer can recharge some batteries to their former charge level – I can attest to that from my earlier rudimentary test. However, in actual prolonged usage on the MP3 recorder recently, I noticed that the recharged batteries get sapped really fast. For example, a brand new battery of the same model would last about a couple of hours, while the recharged one lasted less than an hour (I can’t remember the exact figure). I wonder if this is to be expected.

    The second point is whether recharging non-rechargeable batteries make them more susceptible to leaks. From my experience thus far, it seems to be so (4 out of 8). In the larger scheme of things, obviously a sample size of 8 is way too tiny to arrive at any rock-solid conclusion about the performance of the battizer. On a personal level, however, 4 out of 8 is already enough to make me lay off the battizer for good.

  • We: Thanks for your feedback. I have only one bad encounter (leak) with the batteries (alkaline). The reason is simple. I used an old ones that already showed the symptom of leaks.

    Anyway, I used the Battizer more on my rechargeable batteries. So far, so good.

  • monetr hunter

    Rule of the thumb: Alkaline batteries are very highly prone to LEAKAGE.

    While with a special charger ordinary alkaline cells can be recharged there’s like a few considerations. Use them with extreme caution. They’re very prone for leaking in plenty of my personal experience.

    It’s wise to hadle the battery with care if you don’t want them to leak in your equipment. You will have a lot of leaky batteries. These Battizer batteries are “Super alkaline” which I highly suspect have extra chemicals to reduce the reaction that causes alkaline batteries to leak. Those batteries will still leak after after a year or so. There are also various battery manufacturers also sell these kind of “Super alkaline” batteries like e.g. GP.

    Also alkaline batteries chargers isn’t new at all and has existed since the very early 90s sold under various brands names.

    Take note, alkaline batteries do not fully recharge (Read: Not 100% of the rate of what they used to be).

    A better alternatives would be investing in LSD (Low Self-Discharge) NiMh like Sanyo Eneloops or MAHA Imedion:

    http://www.eneloop.info/

    http://www.mahaenergy.com/store/PR_IMEDION.asp

    The Eneloops have a practically proven life cycle of being charged of up to 1500 times, comes pre-cahrged out of the retail pack, rechargable LSD MiMh will never leak and best off it’s very suitable for high-drain devices like D/SLR users with flashguns, remote controls, wireless devices, etc. Risk losing your precious equipments or get something proven that will save your bucks and the environment, you decide.

    Please don’t any how sell to overseas, it shall tarnish Singapore and make future true product difficult to sell.

    First, primary alkaline charging has been around for a very long time. I bought one 20 over years back, promoted by OUB card. Surprise! surprise! surprise..it did not really work.

    1. The worst problem is the leakage, never mind it does not work. It shall create much more problem.
    Overcharging, multiple charging, and time shall increase this problem.

    2. Then it is the charge-holding duration, it can hold charge. It can’t hold more than a few days.

    3. The number of time of recharging, maybe 5 to 6 time is OK. After that, you shall waste a lot of time troubleshooting why because you resist blaming a S$85 charger).

    4. The best way to charge is charge the cell before it drop below 1.3V, best 1.4V, and even better after each use. Seriously, you search around, you shall find it is true. But it defeat the purposes.

    5. The battery is not researched in Singapore, I think a local guy just bought it from China, and re-brand it. To be convincing, they should not try to wear the “safety goggle” while demo their product in an office environment (promo video). Don’t do that, it tarnishes local name, and make real local chaps difficult. There are good China stuff around, research, QC and choose those.

    6. If it is a breakthrough, what is the technology comparison. I had played this, I think the best method should be a low current (less than 50mA) pulse charging with cut-off voltage monitoring. Low current and pulse, so you don’t rupture the cell by having too much chemical activity inside. Voltage monitoring so not to overcharge. With this, the cell is unlikely to get hot, but charging shall be very long. Give a hint.

    7. The killer of all – the cell manufacturer shall keep changing the cell to make it cheaper and better as they are not made to be rechargeable. So even the best method may not work few months down the road.

    The above problem is not either or, they are all happening at the same time.

    Please prove me wrong. Email “sm dot ling11 at gmail dot com”

  • Vaule$: Thanks for the valuable information. For the comment on the unit getting hot, I did not get it. The battery can be charged in an hour or slightly more.

    Have you tried it before? It is correct that the technology has been here many many years ago. But it seems that it may have improved. I am not an expert in this field. It is based on my usage.

    So, do share more information with us ๐Ÿ™‚

    Many thanks.

    As an engineer, I am concerned that Battizer claims to charge rechargeables in 1 hour with just 250mA current. Simple maths will tell you 250mA in 1 hr gives just 250mAH of energy (assuming 100% efficiency). With most modern NiMH being well above 2000mAH, you get only 10~15% charge! Unless Battizer have a way to circumvent the law of physics?

    Furthermore 250mA is about 0.1 to 0.15C charge rate, which is ‘safe’ enough to practically leave in charger overnight. Hence while it is safe to use it to charge rechargeables, I think the full after 1 hr claim is a joke.

    My experience with older models (Rayovac & china clone) on Alkaline battery is the same as most other posters. Yes, it will charge a little because it is easy to get the voltage back up. But most of the recharged batteries will be drained in very short time.

    At least the other chargers are quite truthful in that:
    1. Need to use their special batteries for best results
    2. Must recharge ASAP after use.
    This has to do with battery chemistry.
    There is a fairly detailed explanation why this is so.
    And why the process cannot be reversed after some time.
    And that interval is fairly short (hours).

    Mind you, I only experienced 1 leak but it leaked in the Rayovac charger while charging! However, I would put that down to poor battery condition.

    As some later posters says, I would rather go for eneloops or the new long life NiMH batteries.

    Hey. When I charge it, the battery will be kind of hot but it is normal?

  • Ken: I do not have this experience when I use Battizer. The batteries usually are warm, not hot.

    I’m only looking this up because I’ve had 2 leaks out of 8 batteries each probably recharged only twice. I now know I’m not the only one suspecting that charging Alkalines gives them a good chance of leaking. I spent quite a lot of time cleaning up and I think exposing myself to caustic alkaline chemicals. Once the batteries that came with the charger are spent I think I’ll go back to NiMHs. I had hope and spent $99 to learn that Battizer needs to fix the leakage issue. They should offer us exchanges when they come up with an improved non-leak product.

    I think everyone need to understand the chemical content of battery and what occurs during charging. When charge is applied to the zinc anode (negative)casing and carbon cathode(positive)rod in between there is a white damp chemical paste called an electrolyte, a chemical reaction occur and gas is released inside the battery casing. Rechargeable battery has a small hole to allow gas to escape. The hole may be visible or hidden beneath the silver cap.
    Since normal(alkaline) battery do not has the hole, gas built up in the case and will cause the battery to explode if sufficient pressure is accumulated. see here http://en.wikipedia.org/wiki/Battery_%28electricity%29#Dry_cell and here http://electronics.howstuffworks.com/battery4.htm.

    Battery leaks due to the fact that the casing(zinc)is worn out by the reaction with the rod (carbon) and the damp electrolyte.

    IMHO, you may recharge the alkaline battery but be aware of the risks to yourself when it explodes and your equipment when it leaks.

    dont forget to do your R and D on the ‘Giant’ brand Alkaline Battery

    Alas even the Battizer-provided batteries have leaked inside and outside of the casing. Less than a year old. Charged less than 5 times. Dismay.
