I'm from the old school where when I use 2 rechargeable cells (be they Ni-MH or Li-ion) in any device, those cells have always been used together as a pair their entire lives. As a rule I will not take one of the AAs out of a 2xAA light and use one of them alone in another light only to recharge them and then put them back in a 2xAA light. They get discharged together, and they are recharged together. Another thing I just won't do is use a battery charger that charges cells in pairs on one charge circuit. So if for any reason one cell is at 70% and the other is at 85%, once the cell that started at 85% reaches 100% and peaks, the charger will have to decide to either stop, in which case one cell is at 100% and the other is at 85%, or it keeps going, and one cell gets overcharged while the other approaches it's peak. I will only use chargers that have an independent charge circuit for each individual cell.
