How do you calculate how long a battery will power a device?
To determine how long your battery will last, calculate the battery’s total capacity and divide it by your circuit’s power. Multiply the battery’s reserve capacity by 60. With a reserve capacity, for instance, of 120: 120 x 60 = 7,200.
How long will a 100 Ah battery last?
A 100ah battery can provide 1 Amp for 100 hours, 2 Amp for 50 hours, and 3 Amp for 33 hours. A simple example, but heavy user of power, is a hair dryer that is 10 Amps. A 100 ah battery will give you 10 hours of use.
