fixing a bad cell
hello guys im just wondering is there any way to bring back a bad cell? i had one go bad (ib4200) and was wondering is there anything i should try to bring it back to life or is it a lost cause and do i just junk it...........

i tryed charging it normal and slow but it wont hold any charge it reads voltage until you put any load on it then it is just reads dead if i charge it (just the one cell or the whole pack i tryed both) and put the pack in a smart tray it just goes dead in a second or two :cry:

you will have to disassemble the pack and check each cell with a meter, then just replace the bad cell.

I have the same problem. I figure we are SOL.:flaming: I was considering disassembling one of the other packs to get my other three back to a full six cell. instead of a 5 cell.

Sometimes you can revive it if you charge the cell at a really low rate but I have only ever seen it work a couple of times.

Ive revived a few dead/0 volt cells with a quick 1 second touch from a fully charged pack. Sort of like a mini zap.

the older ib's die and theres nothing you can do.but its offroad you run,its not on road where this would matter.
buy new cells is the only answer,or go lipo.:)
