Ricoh Caplio 10G Replacement Battery 3.7V 850mAh

Ricoh Caplio 10G — 3.7V Li-ion Replacement Battery

This 3.7V, 850mAh Li-ion cell is a direct replacement for the Ricoh Caplio 10G compact digital camera. It slots into the same battery compartment as the original and powers the camera through photo and video capture. Capacity is 3.15Wh — identical in spec to what Ricoh shipped in the original unit.

• Caplio 10G platform fit: The Caplio 10G uses a slim 3.7V single-cell Li-ion pack measuring 40.20 × 35.30 × 6.10mm. This cell matches those physical dimensions and the voltage rail the camera body expects. The BMS on this pack communicates charge status back to the Caplio 10G's indicator circuit.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the bench. The BMS engaged correctly at low-voltage cutoff and did not trip during simulated flash-capacitor recharge current draw. Charge acceptance from an OEM-compatible charger was clean with no thermal anomalies.
• First-use charge cycle on the Caplio 10G: Run one full charge cycle inside the camera body or OEM charger before your first shoot. The Caplio 10G maps its battery-remaining display to a voltage curve — skipping this step can cause the indicator to read inaccurately from the first frame.

Flash capacitor recharge current sag on a new Caplio 10G cell

The Caplio 10G's built-in flash draws a sharp current spike each time the capacitor recharges between shots. A new cell at partial state of charge can deliver a momentarily lower voltage than expected during that spike. If the BMS reads this sag as an undervoltage condition, it may briefly interrupt power to the flash circuit. Running the first full charge cycle before flash-heavy shooting lets the BMS calibrate to the cell's actual discharge curve and reduces false cutoffs.

Battery percentage jumping erratically on the Caplio 10G display

This happens when the camera's indicator circuit maps voltage thresholds to a discharge curve it has not yet learned from the new cell. The Caplio 10G reads voltage at intervals and translates that into a percentage — a replacement cell with a slightly different mid-discharge voltage profile can cause the indicator to skip levels or jump backwards. It is not a fault with the cell. Perform one complete charge-to-full, then run the battery down in normal shooting conditions, and the indicator will stabilise to the new cell's curve.
