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.
