Direct replacement for Compustar remote

This Cameron Sino lithium-polymer battery is built for the Compustar 2W901R-SS JHY190507 remote start and entry system. It restores power to a single key fob so the vehicle responds to lock, unlock and start commands. The cell arrives new and ready to fit.

3.7 V 210 mAh capacity match

The critical specification is the 3.7 V 210 mAh rating, which equals 0.78 Wh. Only a cell with this exact voltage and capacity will keep the remote’s transmit power and runtime within factory limits. A different rating will cause range loss or premature shutdown.

Simple snap-in install, watch polarity

The pack measures 29.10 x 22.82 x 3.50 mm and slides into the fob’s battery cavity. Align the positive and negative contacts exactly as the original cell sat; reversed polarity will prevent the remote from powering up. No soldering or tools are required.

Questions about this item

How long will the 210 mAh capacity run my Compustar remote before it needs recharging?

The 0.21 Ah cell delivers 0.78 Wh at 3.7 V, giving typical remote-start fobs several days of normal button presses before a recharge is required.

Does the Li-Polymer chemistry need a special charger or can I use the original Compustar dock?

The pack is built to the original JHY190507 specification, so the factory charging circuit in the 2W901R-SS system handles it without any extra hardware.

Will the 29.10 × 22.82 × 3.50 mm case fit inside my existing remote housing?

Those exact millimetre dimensions match the OEM battery cavity, so the cell drops straight into the Compustar 2W901R-SS remote without modification.
