External battery life calculator

The calculator helps you to estimate the external battery run time for Ajax hubs or range extenders connected via PSU. Battery life mostly depends on the battery parameters and the number and type of active communication channels. Please note that the calculator provides approximate estimates as many factors affect the battery life.

Select the PSU model:

24V.H2R2.Y
12-24V PSU (type A)
The value is used to check the battery compatibility and does not affect the battery life calculation
Enter “0” if you don't know
