Charge the pack, then open it up. You will have to unsolder the cells because you can't test cells in Parallel. BEWARE - shorting out cells can cause them to EXPLODE - if you short them out momentarily they won't explode - but they will be permanently damaged and useless. A fully charged LiIon cell will be at 4.2 volts and stay at 4.2 volts for months. If it is below 4.0 then I wouldn't re-use it. Before disassembling cells, check that at least some cells are at 4.2v - if not the pack wasn't charging, so you can't test the cells.

I know the easy way to get this working is to go ahead and buy new Li-Ion cells. However, it strikes me as odd that I've got two High Capacity 110 batteries, and a Standard, and they're all dead. Am I wrong in assuming that I can get 4 or 6 good, working cells out of the 16 that are floating about these three packs? If it's possible, does anyone have an idea as to how I would test the individual cell? I can get a multimeter pretty easily, but unless I know what to look for, it's somewhat pointless. And I'm fairly certain that this wasn't mentioned in the archives (I just finished scouring them myself,) but if you want to prove me wrong, please do :-) Thanks, CK ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives -------TO UNSUBSCRIBE------- Reply to any of the list messages.
