I of all people should have known better, but I left 8 or 10 of these kobalt 80v batteries on the shelf and allowed them to run down completely. Two had to be jump started so the charger would recognize them... briefly connect the dead one to a full one to boost it's voltage up a little bit. For the last week I've been cycling thru charging them. What I find is that they'll charge to "two bars" and stop. Well if you let them sit for 24 hours, the internal BMS balances the pack a little bit. Several iterations of this and I now have almost all of them showing 3 bars. It sure would be nice if they had a little bluetooth connection inside so you could see what's up with them, but for now, this is working. Charge, rest, charge, rest, charge, rest, charge full.
