The OnDeck™ GTB 10 hub switches to running on the internal battery when it is not in a full-power state and the voltage of the external power input drops below 11.9 Vdc for a 12 Vdc system or below 23.8 Vdc for a 24 Vdc system. The system type is determined by the voltage of the external power input. Less than 15 V indicates a 12 Vdc system and greater than 18 Vdc indicates a 24 Vdc system.

The OnDeck GTB 10 hub switches back to running from the external power input when the power input rises to 12.4 Vdc or higher for a 12 Vdc system or to 23.8 Vdc or higher for a 24 Vdc system.

The internal battery lasts about 48 hours under typical use.
