Also, maybe note worthy is the fact that the CC and CV are maximum values. Say, for A123's the max recommended voltage is 3.6 (3.8 MAX, 4.2 burst), and the charge voltage is at 5 amps. The charger will never breaking both rules at once... it will pump 5 amps in until it hits 3.6 volts, hold it there, lets the curent die off until no current at all (50mA is cutoff for A123), at which point charge is at 100% SOC (state of charge). Like Brian said.

But the think about A123 M1 cells is that they are very forgiving. You just can't give them a grudge against you. They are very durable to overcharge, under voltage cutoff, and brief short circuits (i did so myself, the tab just disappeared from a flash of light :017: )

Any other questions?
