how old is the battery? It may be less of a hassle to just recycle it. Never heard of anyone repairing threads on a battery but I guess it could be done. Joined Sep 8, 1998 · 2,014 Posts Joined Mar 6, 2009 · 8,339 Posts
I've used use a slightly larger SAE bolt to "stud" it. Put a nut on the bolt and run it up to the bolt head. Stick that in the cable end, then thread it into the battery hand tight. Then run the nut down tight to hold the cable down. Also done this on a stripped out speedo cable hold down in an old transfer case.

Discussion Starter · #6 · May 1, 2016 It was a brand new battery, the original stock battery took a dump. It was actually on my 2005 chevy 2500 hd. The truck has a plow on it. The battery has these 2 small brass adapters that the leads for power , ground and solenoid wires for the plow go under and then the cable screws into the back of that. I thought I stripped the threads out of new
battery when trying to install the cables. I pulled the battery and the threads looked fine. I think the threads just start a little farther in than my old bat. That looked like the brass adapter was not long enough to grab a lot of threads with the other cables under it. The fix, I wrapped the threads on the adapter with tin foil and tightened them up problem solved. so if anyone else ever has this issue maybe this will help them. thanks for the reply's Mike Joined Mar 14, 2021 · 5 Posts
It should Heli- coil just fine. I will heli-coil my battery side terminal tomorrow. I just happen to have a 3/8x16 heli-coil kit left over from a brake caliper mount repair. I will measure the depth and use a 25/64 drill bit. Then I will use the supplied tap and insert tool to add a hardened steel
insert. I will experiment on an old battery before I repair my good battery. Joined Mar 14, 2021 · 5 Posts

You'd have to use a blind tap.
 Ablestock.com/AbleStock.com/Getty Images Batteries provide the direct current electricity to run accessories such as lights, windows and fans for heating and cooling within your vehicle. Two posts on the top or sides of the battery provide connections for clamps on the electrical cables leading back to the rest of the system. Bolts are typically used to secure these clamps. If you need to remove a battery but find that the bolts have become stripped, there are a couple of tricks you can try to free the battery. Step 1Park the vehicle with the stripped battery bolts. Turn off the engine and remove the keys from the ignition. Step 2Release the hood latch. If the vehicle has been operating for some time, wait 30 to 60 minutes for the engine to cool off so you can work safely. Raise the hood and prop it open. Step 3Clean off any corrosion from the battery terminals with a battery terminal brush.
Step 4Grasp the end of the stripped bolt with a pair of locking pliers. Tighten the pliers to secure. Turn the pliers and try to dislodge the bolt. Step 5Cut the bolt away from the terminal connector with a hacksaw. Take care when working around the battery and try not to cut the battery or terminal post. Use steady pressure and move the hacksaw back and forth slowly. Step 6Use a pair of pliers, if needed, to pull the clamp away from the battery post. References Things You'll Need

Thankfully, you've probably got a flexible conductor sitting in your kitchen cabinet -- aluminum foil.
