Cleaning tools that batteries corroded in.

Damn if that isn't a great idea!
Could have used something like that to clean old thermostat contacts that corroded over time due to soldering flux residue left on them during manufacture.

Sure thing. This is what I purchased most recently:

You dial the knob at the back, and it advances a bundle of glass fibers that slowly wear back like an eraser. It doesn't quite have the power of a sandblasting pen, but it doesn't require any additional equipment either.

This style "scratch brush" is also made in stainless, brass and nylon, and I've got them all, but it is the fiberglass one that really shines, because the glass breaks as you use it, so it stays sharp.

re reading the thread.......... great idea.
need to 'add to cart' (again!)

Get a screw with thick/course threads and screw it deep into the end of the battery. Now attach a slide hammer like they use in body shops to pull out dents.

After a couple aggresive slides you should be able to remove the bad battery(s).

Forgive me if I should know this already, but what's the risk of the puncture sending acid in my direction?

None, because there’s no acid in alkaline batteries. But safety squints are recommended anyway for this sort of task.

For mission critical items that get used rarely (such as a flashlight in an auto emergency repair kit) I use energizer lithiums. They are good for 10 years plus. Just make sure that the device you put them in doesn't have parasitic drainage.

This is a very important point on the parasitic drainage!

I have a pair of 2-way radios that I had lithium AAAs in for a number of years with no use. I removed the batteries and tested them and found that one out of the three batteries in each radio was lower than the other two - this is apparently due to the fact that the electronics draw a tiny amount of current from only that one battery, even with the power switch turned off.

So for true long-term storage, lithium batteries, kept together with whatever they are powering, but not installed.

Most of my leakers have been Duracell (even some unused, still in the package!!), though there's been a few Energizer too.

Lately I'm focusing on basic Rayovac alkalines. They have better prices and work just as well, with what seems to be less propensity for leaking these days than the bigger brands. I've found them at Walmart, Kohl's, Home Depot, and Lowes.

Rayovac is now being bought up by Energizer! https://www.usatoday.com/story/mone...pends-2-billion-add-rayovac-brand/1035331001/

"Energizer will spend $2 billion in cash to acquire the battery and lighting assets of Spectrum, adding the Rayovac brand to its battery and lighting division."

Hopefully they will maintain separate operations/formulations to still give customers a choice...
