With regular AA alkaline batteries, when they corrode, it is time to throw
them out.

With rechargable AA alkaline batteries, is it also time to throw them out,
or can you clean them up and recharge them? I have never had that happen before until recently so I was not sure.

you mean corrode or actually leaking out material like batteries sometimes do? if you are losing the material inside, then toss them. if they rust, you can get a scotchbrite and buff the rust off.

also there's different types of batteries. lithium is dangerous shit. don't risk anything with lithium batteries. i had a battery that i suspected was lower capacity and had a fake label over it. i used an xacto blade to get the label off to see the real one under. I knicked that fucker somehow and it ignited. I had to put it in a bucket with dirt to cut off the oxygen.

If they're NiCads, they tend to build up memories which can be "fixed"
by temporarily shorting the battery out, however, if they're older than
three years, I'd just recycle them and get new ones. LiOn rechargables
I'd be a lot more careful with due to their propensity to explode.

I call it corrode. It is on the terminal ends and looks like the stuff
that forms on car battery terminals.

I checked. I said "alkaline" but they are actually NiMH batteries.

They are NiMH and are certainly older than three years. I will probably
just toss them and get new ones.

yeah if they leak, toss them. is there a lot of white powder?
but check out the device for defects.

I have seen Doctors clean corroded batteries from cheap equipment and keep using it. Batteries are cheap so I would not risk it if the batteries were really really bad.
