Ricoh DB-70 Caplio R8 Replacement Battery 3.7V 1050mAh

Ricoh Caplio R8 / R10 Series — 3.7V Li-ion Replacement Battery (DB-70)

This is a 3.7V, 1050mAh Li-ion replacement for the Ricoh DB-70 battery. It fits the Caplio R8, R10, R7, and R6 compact digital cameras. Same voltage, same form factor, same connector as the original cell.

• Caplio R-series compatibility: The R6, R7, R8, and R10 all run on the same 3.7V rail and use an identical DB-70 footprint. The battery compartment dimensions — 40.60 × 36.26 × 7.10mm — and the contact layout are unchanged across this generation, so one cell fits all four bodies.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a Caplio-series body. The BMS accepted the cell without fault flags, voltage held stable through the discharge curve, and the camera body reported charge state normally at each threshold.
• First-cycle conditioning on the Caplio BMS: Charge this cell fully inside the camera body or the OEM charger before your first shoot. The Caplio BMS maps battery-remaining percentage against a stored discharge curve — running one complete charge cycle from inside the body gives it the reference point it needs to display remaining charge accurately.

Dead battery indicator on the Caplio R8 with a fresh replacement cell

The Caplio R8 checks incoming cell voltage against a minimum threshold at power-on. A new cell that has partially self-discharged during storage can read below that threshold, triggering the dead battery icon even though the cell is functional. This is a BMS authentication check, not a faulty battery. Place the cell in the OEM charger first — once it registers above 3.6V, the camera body will accept it and power on normally.

Battery percentage jumping erratically on the Caplio display

The Caplio R-series maps its fuel gauge to fixed voltage thresholds calibrated against the original DB-70 discharge curve. A replacement cell with a slightly different discharge profile can cause the percentage indicator to jump — skipping from 80% to 40% in a few shots, or stalling at one level then dropping suddenly. This is a calibration mismatch, not a capacity defect. Run two full charge-discharge cycles through the camera body and the indicator will stabilise as the BMS recalibrates to the new cell's actual curve.
