    Posted: 19 October 2023 at 04:04
I bought a camera bag at a local thrift shop that included a Canon film camera and some lenses. One of the two AA batteries had leaked and swelled up and won't come out. I found a YouTube video on how to remove it by drilling a hole into the center and then inserting a screw most of the way down and pulling it out with the screw. Does this sound safe to you guys? Is there any other way to remove it?

If you've got the rest out , can you not bend a thick piece of wire into a hook to fish the other one out ?

If not , then yes , I would probably drill it and put a screw in it to pull it out .

From a safety point of view , these are probably dry alkaline batteries.
The stuff that is them might come out of it while removing it will be corrosive and is best kept off the skin .
So wear disposable gloves .

That said I've messed about with leaking batteries without gloves and just washed my hands afterwards.
Your skin might react badly , so better safe than sorry .

For cleaning up the crud from leaking batteries I use white vinegar , followed by removing the vinegar ( acid ) with distilled water out of my dehumidifier, then allowing to fully dry .
Battery trays out of vertical grips are the mount ones I've cleaned up where I just drop it in a tray if white vinegar, in the battery holder in flash guns , I just use a small artists paint brush .


It's possible that in the camera body where the wire is soldered to the wire spring of the battery contact might have corroded .
If so the camera might still be dead without repairs , but you've nothing to lose .

Good luck .

I'd try to clean and remove the corrosion first, should make for a less restrictive removal. It is safe to screw into a dry battery, if you find the screw pulls loose before the battery does look into the 'super glue and baking soda trick' for a stronger bond. I've even seen where instead of using baking soda as a filler they used crushed carbon powder taken for a dry cell battery.

Thanks! I'll try drilling it out. There is no way to clean around it. It's a slot type hole so only the top of the battery shows.
