Battery case repair

old · Sep 5, 2010

Well yesterday I had the battery in my truck fall out of the battery box and got into the pulley of my air compressor and cut a hole in it. So have any of you ever repaired a hole in a battery?? It is close to the top and the battery is still good so I would hate to junk it just because of the hole. So any ideas?? I was thinking JB weld and maybe a patch of some sort??
Thanks

maybe some kind of an epoxy? I have tried to fix a cracked battery and I did not have too good luck,the acid ate through ,good luck with it if you find something that works post it

using an electric soldering iron (not gun) I have successfully melted a weld into the hole. Often a carrier strap can be made from the same plastic as the case and is handy to use. Set the battery so the acid is away from the hole, and work it like a weld. Jim

You used to be able to buy a product made for this--[plastic welding stick) use it with soldering gun.

That sort of brings back a memory of roofing tar on a battery from almost half-century ago. But I don't recall what I was trying to do! Probably read a tip in Popular Mechanics and was trying a youthful experiment!

I've used RTV silicone with good results.

I had a neighbor who managed an auto rental agency. He owned a farm and had two teen boys at home doingthe farm. The boys saw me tapping a batterry cable clamp on the post and they learned my SKILL. They made a pracice of driving the clamps on with a HAMMER !!! They drove the posts down into the battery and the old man would bring home a couple of new batteries from work (Paid for?) and gave me the old ones. I pulled the posts up and used roofing cement and had good Delco batteries for some time. Boys have done well and the old man died a few years ago.

My son works at a fiberglass outfit. We repaired one that had a hole in the bottom. It is still in use after 2 years.

RTV gasket sealer. Acid does not attack rubber. JB weld gets hard and could loosen and leak with the heating/cooling cycles under hood. I fixed a battery that got into the fan of an alternator once with RTV. I refilled it with acid from another junk battery. It lasted another 2 years and never leaked.

Hot glue gun with heatgun to heat plastic first.BTDT and you probably already have all you need,no point and buying more to clutter the bench you already can't find.
