Direct replacement for Pronto remotes

This Estry lithium battery replaces the original pack in Pronto TSU9400 and TSU9300 remotes. It matches the factory voltage of 3.7 V and delivers a rated capacity of 1800 mAh. The cell is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards. A built-in protection circuit guards against overcharge, over-discharge, over-voltage and short circuit.

Suits owners of listed Pronto models only

The pack fits the TSU9400, TSU-9400, TSU9300 and TSU-9300 handsets and matches part numbers PB9400, 530065 and C29943. Buyers with other remote models or different part numbers should look elsewhere. The single-cell format means it cannot serve devices that require multi-cell packs or higher voltages.

Steady output during extended use

The 1700 mAh nominal capacity and 6.29 Wh energy rating support long operating sessions between charges. Protection circuits maintain stable voltage under continuous drain and prevent damage from deep discharge. At 53.6 g the cell adds minimal weight to the remote.
