How to Safely Discharge a Capacitor?
The best way to select a proper resistor is to use this formula: P = V²/R, where P is the power in watts, V is the voltage across the resistor, and R is the resistance in ohms.. For example, let''s say you''re discharging a capacitor with a voltage of 25V. If you wanted to use a 100ohm resistor, then you would need a power rating of at least 0.25W (25V/100ohms = 0.25).

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.
