Standby Power Battery Sizing: Methods of Calculation

Important: Any critical sizing calculations must be verified with First National Battery.

The battery manufacturer needs to know what is required in terms of current output, voltage, and frequency of operation. This information is known as the load profile.

The examples shown here are merely intended to illustrate the steps to be taken to determine the cell size to meet the duty specified.
