So a 1c charge rate for a 2200mah battery would be 2.2 amps, as the battery capacity is 2.2 ampere- hours. If your charge the battery at 4.4 amps, that is a charge rates of 2c (2*2.2=4.4). Think of 2c or whatever the c rating is as an equation- this equation works both for charging rates and discharge rates.
