Sorry for asking this question as I am sure it has been covered before but i couldn't find much info on this subject.
Got home this evening and went to charge some batteries to find that a 6s 3000mah battery I have used possibly once or twice has one bad cell (0.10v lower than the other 5 cells - 3.75:3.85:3.85 etc). Hasn't been touched for about a year and was stored at 3.85v when i put it in the ammo box.
I have balanced charged it on my icharger 3010b, but the bad cell is still reading 4.12v whilst the rest are 4.20v. Discharged the pack to 3.85v and it again is down at 3.75v and lower.
Perfectly happy to say the battery is dead and dispose of it. But there are no external signs of puffing and the IR are 6:3:2:3:3:4
Any thoughts other than cycling it a few more times or cutting my losses and disposing it? It's a turnigy nanotech, so not a great deal of cost to me (unless it spontaneously combusts!)
