Replacement Battery for Compustar Remotes

This 150mAh lithium-polymer cell replaces the original power source in Compustar 2WT11R, 2WT11R-SS, 2WT12-SS, P2WT11-SS, Pro RFX T2, Pro RFX-P2WT12 and RFX-P2WT12-SS remote start and entry systems. It delivers 3.7 volts and 0.56Wh in a 25.20 x 19.00 x 4.30mm package weighing 3.2g.

Steady Output for Daily Remote Use

The cell maintains its rated voltage across repeated lock, unlock and remote-start activations rather than only in brief bursts. Built-in protection against overcharge, over-discharge, over-voltage and short circuits helps the battery sustain performance through many charge cycles.

Verify Model and Connector Before Ordering

Match the part number JHY442027 and the exact model of your remote to the compatibility list above. Ensure the connector aligns correctly during installation and allow two to three full charge cycles for the new cell to reach optimum capacity.

Questions about this item

How much heat does the 3.7 V lithium-polymer cell produce during continuous daily use in a Compustar Pro RFX T2 remote?

The 150 mAh cell runs at low current draw in a remote, so it generates negligible heat during all-day operation.

What must I already own to install this JHY442027 replacement battery?

You need a compatible Compustar remote such as the 2WT11R, 2WT12-SS, P2WT11-SS, Pro RFX T2, Pro RFX-P2WT12 or RFX-P2WT12-SS, plus a small Phillips screwdriver to open the case.

Will this 25.20 × 19.00 × 4.30 mm pack fit alongside the original circuitry in my older Compustar 2WT11R-SS remote?

Yes, the dimensions match the OEM battery exactly, so it sits in the same compartment without forcing any surrounding components.
