anyone tried to recharge non-rechargable batteries ?

Yes, I have tried it. You can do it by pulsing the charge current. It's an interesting experiment to try, but it's not recommended, and can even be dangerous. The charge rate must be kept low to prevent gas being produced, which can break the seal (or possibly make the battery explode) and cause the contents to be released.

Basically, it's not a good idea.

I'm using an EnvironPower recharger for Alkaline batteries .
( translated by Bing) :

product information
Alkaline battery charger (EnvironPower)
The very popular and innovative Alkaline battery charger reloads ORDINARY batteries! You can therefore with this particular device both Alkaline batteries "throw-away" as the original rechargeable batteries reload. Equipped with a Dutch manual and description.

Reloads ordinary batteries
-The 1st battery charger of its kind
-The charger is based on a patented technology that ordinary alkaline disposable batteries also can reload
-The charger is designed to reduce the voltage of ordinary used batteries to recharge the batteries, so that time can be used
-From testing has shown that the batteries are sure to 20 times with a great result can be reloaded
-Loading of ordinary batteries is good for your wallet and good for our environment
-The charger can also original rechargeable batteries (Ni-MH) reload
-Works with AA (AA) and AAA (mini-AA) batteries
-9V block batteries NO Reloads


What to say : It works for me , the kids are consuming more power with their toys as Tsjernobil could deliver

Most batteries I've recharged still work , but I had a couple of batteries which got leak

But it is protected against overcharging / temperature to high / change of polarity etc etc

Yes, sometimes it works ok, but (as you said yourself) the batteries can leak. Also, the "recharged" batteries don't last very long after charging. In the end I found it just wasn't worth the bother. If you want to save money, then simply use rechargeable batteries in the first place.

Plain old Alkaline Batteries are not rechargeable.
Leaking Batteries (it happens very often, with all Kind of Batteries, except Lithium)
can get quite expensive... remember to always remove them if the Device is not in use.

My best Friend bought an expensive Minidisk Recorder many Years ago... he put an old AA Battery inside,
played a bit with his new Toy and left it on a Table in Sunlight.
4 Hours Later, the brand New MiniDisk Recorder was dead... Leaking Battery killed it.
He tried to get it replaced / repaired - no Way!

Now Compare the Price of good Alkaline Batteries to the Price of good NiMh Batteries,
and think about the Price of your Electronic Stuff... is it worth the Risk ?

In the 70's I got a miracle battery charger, same as the one pictured below. As mentioned, recharged batteries never lasted very long, and had a horrible tendency to leak.

About 10 yrs ago I was running Ray-o-Vac rechargeable alkalines in my detectors, but eventually abandoned them because they were very sporadic... sometimes a battery would last 100 cycles, sometimes only 5. Now I use only NiMH.

makes you wonder why they used a pretty female to advertise this product ha ha

A leaking battery can cause more damage compared to the price of a new battery.
I only use the recharged batteries for the kids toys ( you would be suprised how many kids toys use AA or AAA )

The Charger itself can handle NiMH batteries perfectly btw .

The only problem I had with some NiMH batteries is the relative high self discharge.

It happened frequently ( for my digital photocamera ) that my spare set of AA NiMH batteries were discharged in a short period of time .( wrongly charged ? )
Ofcourse this happens when needed them the most.

Now I use Sanyo Eneloop NiMH ( it was not a brand high in my recommendation list ) .

http://www.eneloop.info/home/faq.html

Sanyo claims that after 3 years , a fully recharged battery still has 75 % of its capacity ...

I didn't wait that long but whenever I needed my 'spare' set they did their job well.

Perhaps the only 'disadvantage' is the lower capacity ( 2000 mAh for AA ) but it seems that they are working on that issue .

Hello I have the alkaline charger Rayovac model PS3, I charge some alkaline bat.
for wall clock, etc.,
But now I use new charger NiMH. and bat. 9v. sony 400mAh and Duracell 2650 mAh

I worked with an old guy who said you req dirty DC

essentially on a full wave bridge rectifier you needed a resistor across some of the diodes so you got a little bit of negative out with your mainly positive.


This was his view, never done it myself.

Good batterys I like come out of Laptop battery packs - most offices have a few knocking about that are low capacity/short time of use,,, carefully split them to extract 1.8AH 4.2v cells (one is normally bad) the other 5 are good.

Lithium polymer used fr model aircraft are good too.

Also the cells in dewalt Lithium battery packs (A123 type)

to clarify this topic ordinary batts alk,lead acid,etc cannot be recharged but can be reconditioned argos and b+q sell reconditioners mainly for energiser and duracell types and they work well typically achiving 80% charge first time and then dropping gradually at every cycle after that if you use a lot of alks the reconditioners pay for them selves in no time and they charge nicads and nmh and l-ion too so a winner all round

p.s reconditioning does not have the leak issues

p.s reconditioning does not have the leak issues

The use of the word "reconditioning" is just a marketing term. These chargers are still attempting to reverse the chemical reaction in the electrolyte, which is basically "recharging". I suspect they're using the term "reconditioning" (with regard to alkaline batteries) as they're not designed to be recharged. Modern alkalines are probably a lot better than the older types at being recharged, as many of these couldn't even take one recharge cycle.

Although there do appear to be several satisfied buyers, you cannot categorically state that the leakage problem definitely no longer exists. Personally, I wouldn't trust it. As someone said earlier, the potential damage due to leaked batteries doesn't justify the savings gained by trying to "recondition" depleted alkalines.
Take a look at some of the negative customer comments: ->

i tried charging d size batteries and they started leaking after a short time while being charged,the AAA batteries would not charge and the AA batteries would not hold there full charge for a couple of days,just sitting.i think that the charger may be a little over rated.i purchase 2 of the charging units.

This product does not seems to chrage alkaline batteries properly. It showed most discharged alkalines as either OK not needing a charge or as bad and unchargable.

Hi all,

yes, i m probably ,,recharging'' the 1,5 V graphite-zinc batteries only in the 80' years with wide-range results. No good for alkaline batteries!

The ,,quick charging'' method is very simple and very dangerous:
Must be an 6-12V/50Watt transformator and min. 4-5A Graetz, without puffer capacitor.
Simple connecting this circuit the 1,5V battery, but only maximum 4-5 sec!

Distance the between human operator and batteries at least 1-2 meter!
Sometime the ,,charged battery'' is exploding while ,,charging'' (garage-work, the battery is in the plastic bucket)! The ,,charged battery'' is hot!

After ,,charging'' must be waiting 1-2 min, and probably the result.

The ,,recharged'' graphite-zinc batteries is average 4-5 times reused with this mehtod.

I m probably this method with alkaline batteries, but NOT WORKING!

actually i was refering to a particular regenerator but i cant remember the name as i understand it the unit i was trying to reference has a strict german patent all others are basically the usual type with mods but like i said cant remember the name the link i provided was one in the usa as an example reading the posts on that link it seems that unit has a high faliure rate the one i was thinking of costs from memory £69 and is in a whole different league and has smart tech to prevent leaks it also charges lithium ion which cheaper ones dont
