Replacement for Compustar remotes

This 150mAh 3.7V lithium cell replaces the original battery in Compustar 2WT11R-SS, Pro RFX T2, P2WT11-SS, Pro RFX-P2WT12, 2WT11R, 2WT12-SS and RFX-P2WT12-SS remotes. It matches the JHY442027 part number and delivers 0.56Wh of capacity for reliable transmitter operation. Buyers who need a different voltage or a higher capacity pack cannot use this cell.

Simple two-wire swap

The pack measures 25.2 x 19.0 x 4.3mm and weighs 28.2g, fitting the existing compartment without modification. Installation requires only disconnecting the old cell and connecting the new one, observing correct polarity. Mistakes occur when the connector orientation is reversed or when the remote housing clips are forced, which can damage the fragile tabs.

Rated 150mAh at 3.7V

The cell provides enough energy for typical daily remote-start and keyless-entry cycles, with over-charge, over-discharge, over-voltage and short-circuit protection built in. Heavy users who trigger the remote dozens of times per day will see shorter intervals between charges. The 0.56Wh rating means it cannot support extended high-drain accessories or devices that draw significantly more current.

Questions about this item

How can I confirm the Estry 2WT11R-SS battery is working correctly after installation?

The remote should power on, show its usual display, and respond to button presses without error messages; a full charge cycle should then deliver the rated 150mAh capacity at 3.7V.

What is included in the package and what must be purchased separately?

The box contains one 25.2 x 19.0 x 4.3 mm lithium cell weighing 28.2 g; no charger, tools, or adhesive are supplied.

Which version matches my Compustar remote — 2WT11R-SS, Pro RFX T2, P2WT11-SS, Pro RFX-P2WT12, 2WT11R, 2WT12-SS or RFX-P2WT12-SS?

Choose the Estry 2WT11R-SS if your remote’s model or original part number JHY442027 appears in the compatible list above.
