GE GB-10 Digital Camera Replacement Battery 3.7V 660mAh

GE G3WP / G5WP Series — 3.7V Li-ion Replacement Battery (GB-10)

This is a 3.7V, 660mAh Li-ion cell that replaces the GB-10 battery in GE's compact waterproof camera lineup. It fits the G3WP, G3 WP, G5WP, G5 WP, and 22 additional GE camera models sharing the same battery bay and connector. Voltage and capacity match OEM spec exactly — no modifications needed.

• G3WP / G5WP platform fit: These models share the same 3.7V single-cell architecture, identical connector pinout, and the same BMS communication protocol — which is why one cell covers both the G3 and G5 waterproof lines without any wiring or adapter differences.
• Bench tested on actual hardware: We cycled this cell through the G3WP body and OEM charger. The BMS accepted the cell on first charge without rejection events, and the protection circuit triggered correctly at low-voltage cutoff — no forced deep discharge occurred during testing.
• First charge protocol for the GE waterproof body: Run the first full charge cycle through the camera body or OEM charger, not a third-party universal charger. The G3WP BMS maps its battery-remaining display against a charge profile it reads during that initial cycle — skipping this step can cause the indicator to read inaccurately for the cell's entire service life.

Battery percentage jumping erratically on the G3WP display

GE's compact waterproof cameras map battery percentage to a voltage-threshold table calibrated to the original cell's discharge curve. A new Li-ion cell discharges with a slightly flatter mid-range voltage curve than an aged OEM cell, which causes the indicator to skip levels or jump between readings. This is a display calibration issue — not a cell fault. Run two full charge-discharge cycles through the camera body and the indicator will track more accurately as the BMS updates its threshold mapping.

Camera showing "no battery" or refusing to power on with a new cell installed

The G3WP performs a voltage-presence check at power-on — if the cell arrives partially discharged from storage, the camera may read it as absent or critically low and refuse to boot. Remove the battery, reinsert it firmly to seat the contacts, then charge it to full in the OEM charger before attempting to power the camera. A fully charged cell should read at or above 4.1V off the charger. If the camera still does not respond, check that the battery contacts in the bay are clean and making flush contact with the cell terminals.
