Direct replacement for Compustar 2W901R-SS

This Cameron Sino battery matches the original 210mAh capacity and 3.7V voltage for the Compustar 2W901R-SS remote start and entry system. It uses a lithium polymer cell and includes a fully decoded chip so the remote communicates exactly as the factory unit did. The pack measures 29.10 x 22.82 x 3.50mm and weighs 4.5g. It carries ISO9001, RoHS and CE certification.

Low self-discharge chemistry runs cool and safe

The lithium polymer cell generates minimal heat during normal remote operation and draws only microamp-level current when idle. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits, preventing thermal events. No active cooling or ventilation is required inside the key fob housing. The chemistry remains stable up to 60°C storage temperature.

Fits the existing fob cavity without modification

The 29.10 x 22.82 x 3.50mm footprint slides into the original battery compartment, reusing the stock connector and retainer. No soldering, adapter cables or case trimming are needed. Replacing the cell restores full two-way remote start and keyless entry range, freeing the owner from carrying a backup fob. Allow two to three full charge cycles for the new pack to reach rated capacity.

Questions about this item

How do I install the Cameron Sino battery in my Compustar 2W901R-SS remote, and what step is often missed?

Open the remote casing, disconnect the old pack, and connect the new JHY190507 connector firmly until it clicks; the step often missed is verifying the connector is fully seated before reassembly.

What maintenance or replacement will this 210 mAh lithium-polymer pack need later?

After 2–3 full charge cycles the cell reaches peak capacity; expect to replace the pack again when run-time drops noticeably, typically after several hundred cycles.

What limit appears first during sustained use of this 3.7 V replacement battery?

The protection circuit will cut output if voltage falls below the safe threshold or if current draw exceeds the cell’s 0.78 Wh rating, preventing over-discharge.
