Alkaline Batteries

[Abugaj01]

Are there any chargers out on the market that can safely and effectively
recharge non-rechargeable Alkaline Batteries? I've always wanted to do this,
but first, they do occationaly explode, and second, it is not very effective,
only allowing about 50% extra useful life.

They *cannot* be recharged.
The best one can do for extending the life, is to de-polarize them.
Since you have discovered that your "recharging" process is dangerous,
don't you think that was a fair sign that something was wrong and that
you should have stopped?

how do you depolorize them?

how do you depolorize them?

Low current (1mA or less) at rated voltage for maybe an hour.
The idea is to convert the fine gas bubbles back into the electrolyte.
One does not get much useable life out of any depolarized battery (any
type), as either most of the electrolyte or one of the plates is almost
completely exhausted.

Alkaline batteries are not reversable. When exhausted, the chemical
makeup of them will not return back to their prvious state. There are
a lot of changes in the battery structure that take place, that are
not reversable.

About 10 years ago there was a charger on the market that the
manufacture claimed it would charge alkaline batteries. This was not
very good. It had to do with re-polarizing what was left in the
batteries that may work for a little while longer. This was a waist of
time and money. This is why you only see these chargers at the flea
markets at times.

Make the investment in to proper chargable batteries and a charger for
them, if you want something that is good and worth the time and money.

Yes, there are! There are some chargers that has a special chip that
controls the charging. You just need to recharge them when they have only
lost half the power or so it is said. My local electronic shop in Copenhagen
offers them but I haven't tried them.
