12V Battery Run Time Calculator
FAQs
How do you calculate 12V battery run time?
To calculate the run time of a 12V battery, you divide the battery capacity (in ampere-hours, Ah) by the current draw of the load (in amperes, A) to get the number of hours the battery can sustain that load.
How long will a 100Ah battery run an appliance that requires 800W?
To calculate, you need to convert the power requirement from watts to amps using the formula: Power (W) = Voltage (V) × Current (A). For a 12V battery, the current draw would be approximately 800W / 12V = 66.67A. Then, divide the battery capacity by the current draw to get the run time: 100Ah / 66.67A ≈ 1.5 hours.
