Determining The Battery Capacity

Determining the Battery Capacity

Manufacturers state the battery capacity depending on the discharge time. In the installation assistant and in parameter Rated battery capacity, always specify the battery capacity for a ten hour electric discharge (C10).

Procedure:

1. Determine the battery capacity C10 specified by the battery manufacturer.
2. If the battery capacity C10 is not specified, determine the battery capacity C1, C5, C20, C100 or C120 and use the following table to estimate the battery capacity C10. This will provide a value that is probably sufficient for commissioning.

Discharging time	Estimation
120 h (C120)	C10 = C120/1.28
100 h (C100)	C10 = C100/1.25
20 h (C20)	C10 = C20/1.09
5 h (C5)	C10 = C5/0.88
1 h (C1)	C10 = C1/0.61

3. After commissioning, contact the battery manufacturer as soon as possible, request the C10 battery capacity and set the correct battery capacity in the installation assistant. In this case, proceed as if you had replaced the battery ( > Replacing the Battery).
