Ricoh DS-6365 Compatible Battery 3.7V 660mAh

Ricoh DM-6370 / SL-58 / SL-68 — 3.7V Li-ion Replacement Battery (DS-6365)

This is a 3.7V, 660mAh Li-ion cell that replaces the DS-6365 in the Ricoh DM-6370, DS-6365, SL-58, and SL-68 compact digital cameras. It slots into the same battery compartment and connects via the same contact layout as the original. Capacity matches the OEM specification at 660mAh (2.44Wh).

• DM-6370 / SL-58 / SL-68 platform: These models share the DS-6365 form factor, voltage rail, and contact pinout. The BMS in each body reads cell voltage from the same two signal contacts, so one cell services all four models without adapter or modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge passes on the DM-6370 body. The camera's BMS accepted the cell, reported a charge state, and completed full cycles without tripping a protection cutoff.
• First-use charge cycle on compact cameras: Charge this cell fully inside the camera body or OEM charger before your first shoot. Ricoh's compact BMS maps its battery-remaining display against a charge curve it calibrates on the first full cycle — skipping this step causes the indicator to jump or stall mid-shoot.

The DM-6370 and SL-series bodies use a voltage-threshold map to estimate remaining charge. A new cell that hasn't been fully cycled inside the camera presents a discharge curve the BMS hasn't yet calibrated against. This causes the indicator to read empty even when the cell holds a usable charge. Run one complete charge from flat to full inside the camera body or OEM charger. After that cycle, the BMS anchors its threshold map to the actual cell curve and the indicator reads accurately.

These compact bodies draw current in short, sharp bursts — autofocus, flash pre-charge, and image processing all pull simultaneously at the moment of capture. If the cell voltage sags briefly under that combined load, the BMS can misread the instantaneous voltage and snap the percentage indicator down by 20–30 points, then recover when draw drops. This is a display calibration artefact, not cell failure. Confirm the cell is genuine by checking resting voltage: a fully charged DS-6365 cell sits at 4.1–4.2V at rest with no load applied.
