Does anyone have tips for getting corroded batteries out of flashlights? (lemmy.fmhy.ml)

I imagine a lot of flashlight enthusiasts have death with this. I've found it's less an issue with D cell batteries and more AA and AAA.

Web search finds info. I looked recently because of similar issue. Most promising approach seems to be drill a hole in the battery, drive in a sheet metal screw, and pull, lubing with wd40 if you can get it around the battery casing. Do this outside with eye protection and gloves as the battery can spew crap when you drill it. The batteries are called alkaleaks for a reason.

Thanks. I wasn't sure if there was a lot of commonly known procedures for this. I might grab a vice and drill out the battery if that is the case.

Other people suggested stuff like vinegar and baking soda, which sounded useless. If you use a vise, obvs wrap the light first. Let us know how it goes.

If you end up with a battery cap in yhe screw or drill, you might be able to pull out the casing with needle nose pliers, likely in pieces.

It hurts if you get gunk on your skin, so try to avoid that.

Eye protection is a great idea.
