Direct replacement for Honeywell PROA7 series
This Cameron Sino lithium-ion battery matches the original PROA7BAT2 specifications with a 5200mAh capacity and 3.7V output. It fits Honeywell Home PROA7, PROA7PLUS, Resideo PROA7C and PROA7PLUSC alarm panels. The pack measures 69.50 x 37.00 x 18.50mm and includes a decoded chip for correct communication with the control unit.
Upgrade from depleted or aged original cells
When the factory-fitted battery no longer holds a full 19.24Wh charge, this unit restores the panel’s backup runtime without modifying wiring or firmware. The jump is worth it if the system reports low-battery faults after mains interruptions or if the existing pack has swollen. Installation follows the same connector orientation as the original.
Limited to 3.7V single-cell alarm backup role
The chemistry and voltage suit only the listed Honeywell and Resideo panels; it cannot power devices that require multi-cell voltages or higher current delivery. The protection circuit guards against overcharge, over-discharge and short circuits, but the pack is not designed for cyclic deep-discharge applications. Storage above 60°C or 140°F accelerates permanent capacity loss.

Questions about this item
Will the 69.50 x 37.00 x 18.50 mm lithium-ion pack fit inside my Honeywell Home PROA7 panel?
Yes, those are the exact dimensions of the Cameron Sino PROA7BAT2, matching the original battery cavity for the PROA7, PROA7PLUS, Resideo PROA7C and PROA7PLUSC panels.
What is the installation step most people miss when swapping the 3.7 V 5200 mAh pack?
After inserting the battery, you must fully seat the connector onto the panel header; a partially connected plug will prevent the system from recognising the new pack.
When should I plan to replace the 19.24 Wh lithium-ion backup battery?
Replace it when the alarm panel reports a low-backup fault or the battery no longer holds a full charge after the initial 2 to 3 conditioning cycles.
