: [SOLVED] Fixing stripped battery terminal

Gotta love side terminals. I have one side that is stripped so the bolt does not tighten very well. It's held fine over the last year, but with the cold it keeps coming loose. It's stripped on the inside of the battery. I called Advance Auto, but they didn't carry anything to fix.

I hate redneck fixes, but I was wondering if putting some JB Weld in there might do the trick. The battery probably has a couple years left in it, so I'd rather fix than replace. Any suggestions?

Oh, I can unscrew the bolt just fine, so it's not stuck in there. Just won't hold very tight.

Thanks.

Frustrating as hell isn't it?? Jump in, seems to have full power, turn the key and nothing happens. At least thats what happened with mine. Took a bit of work to figure out that the battery side post was stripped out and the connection was bad. I looked around and found no real fix for the issue. I ended up buying a new battery.:cool:

Although I've never tried it on a battery, but....what about using a Heli-coil?

Might give that a shot.

Is yours a stock battery post, or one of the extended ones?
It's stock as far as I know.

Its just lead, could you not thread a slightly larger diameter bolt into the hole?
Might be an easy fix.

yeah, I'm sure that would work. I've got an aftermarked bolt for my amp, though. I'll pull it all out tomorrow and try to figure something out. Heck, if I can't fix it I suppose I'll grab a new one and keep this one for a spare.

Tap it to a different thread and use a new bolt.

Dribble some melted solder into the threads and chase the threads to the original size.

Use a heat gun of some sort and melt the lead. Drill it out, and put a bolt in.

Just a thought. Never tried it though. Do not hold me responsible if this doesn't work.

Lets remember, this lead is surrounded by PLASTIC. If you heat the lead to the point that it will melt, the plastic battery casing will be on fire. NOT A GOOD IDEA.:no:

You beat me to it!Melt the lead right out,plus fumes,could explode!

Try the fix used for wood screws.

Put a few straight pieces of solder in the hole and screw the bolt into the hole.

Or try wrapping a thin piece of solder on the threads of the bolt and screw it in. :m2:

Thank you for all the replies. Good news. I pulled the bolt and all this time it was the bolt that was stripped. $2.99 and I was back in business.

This is so awesome that this is bumped to the top of the thread. I just went to Advanced to pick me up a Optima red top and I can not, for the life of me, get the positive terminal in. I think the threads are stripped (hard to tell in the freezing cold dark here in PA) on the bolt.

Did you replace the bolt? If so, was it something you could pick up from a typical auto store and how to you get the original one out?

Any and all help is greatly appreciated!

Most auto parts stores carry replacement battery bolts.

If you can't get the bolt to come out by just unscrewing it, grab on to it with a a pair of vice grips and pull as you turn.

It may take a lot of pressure, but should come out. :m2:
