Buyers who need a different form factor

This battery suits owners of the listed camera models who must replace a depleted original cell. It will not fit devices that require a different voltage, capacity or physical dimensions. Users needing a higher capacity pack or a different connector should look elsewhere.

2500 mAh capacity at 3.7 V

The single specification that decides compatibility is the 2500 mAh capacity at 3.7 V, which equals 9.25 Wh. Confirm your camera uses the FT605075P part number and the exact 76.0 x 50.0 x 6.0 mm footprint before ordering.

Questions about this item

Does the 3.7 V lithium cell use a standard connector or a proprietary pin-out for the RM7764-2HD camera?

The pack is built to the original FT605075P specification, so its connector and pin-out match the RM7764-2HD and RM7764HD cameras exactly.

Will the 76.0 x 50.0 x 6.0 mm dimensions fit the battery compartment without modification?

Yes, the 76.0 mm length, 50.0 mm width and 6.0 mm thickness replicate the factory pack, allowing direct insertion into the Wifi Remote Access 2 Camera Ba housing.

What is the correct orientation when inserting the 97.0 g pack, and what mistake do installers make?

Align the connector side with the camera's socket; the common error is forcing the pack in backwards, which bends the connector pins.
