You know, the batteries you'd use in a multimeter..
Anyone had any luck conditioning these to hold a charge with these chargers? If so, how?
My attempts so far have ended up with all the charge I've put in disappearing within a couple hours after removing the battery from the charger.
In other words, immediately after removing the battery from charging, it looks like it gained a small amount, but gradually as you test it, it all disappears until it's back to about the charge it had before you did anything.

If it is zinc carbon, make a hole, fill some water, then over cook it. But you may only get 10% or less from original capacity.

That battery is a zinc carbon, so I'll give that a try. I guess a lot of batteries these days are the zinc carbons. That snuck by me somehow. I was thinking they were mostly alkaline. I have alkalines too. What of those, then?
10% of capacity isn't much. You mean, only 10% of original capacity will be the battery's new capacity? That's not even worth messing with.

I never drilled holes or put water in them but sucahyo is right, you only get about 10% capacity most of the time. It also depends upon how fast they were drained and how long they were drained. On some batteries that were drained fast and put on the charger straight away I got 25 to 30%

alkaline contain alkali which can burn skin, be carefull.

it seems battery work best in acid or alkalize solution.


If you only use it for clock or remote, it can run about half the original, which can be many months.
