This 4.8V 750mAh Ni-MH battery matches the original part number 255789 for the Pronto Pro 900 TSU7000/37 remote. It supplies 3.6Wh of energy in a compact pack weighing 78.0g. The cell is built to the same electrical and mechanical specifications as the factory unit.

Questions about this item

How do I install this battery in the Pronto Pro 900 TSU7000/37, and which step is often missed?

Open the battery compartment, match the connector polarity to the socket, press the pack firmly until it clicks, then replace the cover; the step often missed is verifying the click that confirms the connector is fully seated.

What maintenance or replacement will this 4.8V 750mAh Ni-MH pack need later?

Ni-MH cells self-discharge over time; recharge the pack every few months if the remote is stored, and plan to replace it once runtime becomes too short for daily use.

What limit appears first during sustained use of this 3.6Wh replacement battery?

The 750mAh capacity sets the runtime ceiling; under continuous operation the voltage will sag after the rated milliampere-hours are depleted, ending the session.
