What Is C-rate? The C-rate is a measure of the charge or discharge current of a battery relative to its capacity indicates how quickly a battery can be charged or discharged. Definition: A C-rate of 1C means that the battery will be fully charged or discharged in one hour.For example, a 2000mAh battery at 1C would be charged or discharged at 2000mA (2A).
Self-discharge rate: The battery''s self-discharge rate is the rate at which the battery loses its charge when it is not in use. If you have ever wondered why an electronic device does not turn on after a period of inactivity, this is because the battery self-discharged until the battery lost enough charge to no longer support device function.
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
