Batteries don't have a long shelf life and a sure sign of it needing replacing is when they don't hold a charge so it's time to replace it with something similar.

I've got a similar problem with my hump pack too. I'd say the easiest option would be to just get a new pack however I'm more interested in replacing my cells so, if you find a way to crack it open without severely destroying the casing, please let me know.

These old hump tamiya's are good show pieces for shelf queens. Invest in some nimh's and you will have fun at a low cost.

There is a thread and I think a tutorial here somewhere. What they did was take 2 vintage packs, cut a top from one, and a bottom from another, fit new Ni-MH/Ni-Cd cells or Li-Po soft pack inside the 2 good halves and bond them back together again.

Thanks for the help! I think i'll use it for display only and run the car with a modern equivalent.Also thanks for the quick response,this is the reason i joined this club in the first place.

I've been searching but I couldn't find it. I don't suppose you're able to give a link?
