      It depends on what you are trying to power, what voltage it operates at and what current it draws . Batteries are rated in “AmpHours”. As a simplified example, if a battery was rated at 5 AmpHours, it could last 1 hour if it was putting out 5 Amps, or it could last 5 hours if it was putting out 1 Amp. So it all depends (that is a very simplified answer and its probably not technically correct! But you get the picture)
