How to Interpret Battery Discharge Curves?
★ Charge-Discharge Rate (C-Rate) is the rate at which a battery is charged or discharged relative to its rated capacity. For example, a 1C rate will charge or discharge the battery completely within 1 hour. At a discharge rate of 0.5C, the battery will be fully discharged in 2 hours.
Battery Charging and Discharging Parameters
When the discharging rate is halved (and the time it takes to discharge the battery is doubled to 20 hours), the battery capacity rises to Y. The discharge rate when discharging the battery in 10 hours is found by dividing the capacity by the time. Therefore, C/10 is the charge rate. This may also be written as 0.1C.

Battery discharge time depending upon load
Battery capacity is a measure (typically in Amp-hr) of the charge stored by a battery. You may think that calculating how long a battery will last at a given rate of discharge is as simple as amp-hours: e.g. for a given capacity C and a discharge current I, the time will be, However, battery capacity decreases as the rate of discharge increases.
