Battery Life; Scenario 1 - Mantracourt T24-ACMi-SA User Manual

Battery Life

Although the T24-RDC has an internal battery it is designed to be supplied from an external battery or power
source.
The low power modes can make a big difference to battery life.
The following scenarios give a guide to battery life and the charts show how long the batteries of a given Ah
capacity would last. In real use the full capacity of batteries may not be usable as the T24-RDC can only run down
to 4.5 V. Operating temperature and self discharge of the batteries will also play a part.
