How do you calculate battery life?

To calculate the battery life of a device, you need to know three things: the capacity of the battery in watt-hours, the power consumption of the device in watts, and the efficiency of the device. The capacity of a battery is usually stated in milliamp-hours (mAh). To convert mAh to Wh, multiply by 0.001.

What is the rated capacity of a lead acid battery?

For lead acid batteries the rated capacity (i.e. the number of AH stamped on the side of the battery) is typically given for a 20 hour discharge rate. If you are discharging at a slow rate you will get the rated number of amp-hours out of them. However, at high discharge rates the capacity falls steeply.
