well im going to probally sound pretty stupid....but here goes....

i bought a bunch of batteries from ebay a bit ago...when i got the packs 1 cell was dead, is there a way to bring the cell back to life?

currently the cell is removed from the 6-cell pack, and is an ib3800 507sec @ 1.215v (seller said he was sending another cell to replace - is a ****** Brand dealer, when i got the packs they where only assembled)

my charger is only for 4-8 cells (indi 16x9) or i would try to charge just the single cell....

someone said that i might want to try and find someone with a Turbo 35 and a single cell holder......and that sometimes a good zap will bring them back....

is this true?

I've had no luck reviving dead IB cells. They were probably old cells that sat around for a long time and went to 0volt.

but it was only one cell....wouldn't it be most likely that multiple cells would be dead in a situation like that? one single cell left me believing it might be a crystaline buildup in the cell.

Are a 50% of possibilites you can "revive" the cell with a Zapper. I have a zapper make for me, and i revive some dead cells 3300,3600,3700,3800,4200, but a small amount of cells, I have not been able it to do. In general, the "revived" cell, work well, but is best, to put all the cells, from the same pack, on the zapper.
Although the manufacturers recommend not to do it but of once, I have experienced some years with batteries, that continue working very well.

there is a short in the cell
and there is nothing to do to bring them back
they will work but not as good

Make sure it is dead and what it looks like. If it is all white on the positive side, and looks like it vented there bad, it is done. If it looks fine, but just seems soft or false peaks, a cycle may help, but that's just a guess without seeing it.

um hmmm put 1000 ma in it than in a week if the cell reads 0 than its dead or it has a short in it
