Normal Alkaline batteries can be recharged !

Have a look at this.

Normal Alkaline batteries can be recharged,
if you don?t put too much current through it
and don?t leave it longer than 1 hour in the charger.

I recharge alkaline batteries for years.
After recharging, the voltage is around 1.2 v instead of 1.5 v when the battery is new.
The capacity is similar to NiCd batteries so it's not too much.
Any type of alkaline batteries are not suitable. With some trademarks the batteries can be recharged only 2 ou 3 times before they die. For others it's much more but always much less than real rechargeable batteries.

Yes i do this over years.
some companies sells also 1,5volt rechargarble batteries.
(Germany  Comrad  abaiut 2000/2002.

Ray o Vac i think from US.

The only problem is, its need an special recharger.
Bateries will leackage or explod if load with normal cahrgers.

If you reconstrucht your charger (zener-diodes  or 3x 1n4007) that the voltage can not come over 2,0 to 2,1 volts in the battery, than you can charging this "batteries" without trouble.

Give attention that the batteries will not think under 0,6 volts, SO this way, tey can be charged up to 25 times.

Be happy , with this knowledges.

P.S.
The batterie industry KNOW this possibility, BUT they are
NOT INTERESTED , that this knowledges will be officially
comes to the consumers.

This is an knowledge that disturbe the buisinesses.

Can you post a schematic for an alkaline battery recharger?


I have a whole box full of dead AA batteries.
