Calculation example using the 5h and the 20h rating

The C5 rating is 75Ah. The t1 rating is 5h and I1 is calculated:

The C20 rating is 100Ah. The t2 rating is 20h and I2 is calculated:

The Peukert exponent is:

A Peukert calculator is available at

.

Please note that the Peukert exponent is no more than a rough approximation of reality. In case of very high currents, the battery
will give even less capacity than predicted by a fixed exponent. We do not recommend changing the default value in the battery
monitor, except in the case of lithium batteries.
