Philips C625 Replacement Battery 6V 4200mAh Ni-MH

Philips C625 / CPL-915 / CVL-345 / M620 Series — 6V Ni-MH 4200mAh Replacement Battery

This is a 6V 4200mAh Ni-MH replacement battery for a range of Philips digital cameras including the C625, CPL-915, CVL-345, and M620 among others. It covers 33 compatible models sharing the same voltage rail and battery bay dimensions. Capacity is 4200mAh (25.2Wh), drawn from the product specification — not estimated.

• Multi-model fit — C625, CPL-915, CVL-345, M620 and 29 more: These models share a 6V cell format and the same physical bay dimensions (88.95 × 47.55 × 36.50mm). The Ni-MH chemistry and connector configuration match across the series, so one cell covers the full group without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on compatible Philips camera bodies. The BMS accepted the cell without fault flags, and the capacity readout tracked consistently through draw cycles under both standard shooting and flash-active conditions.
• First-use charge cycle in-body: Insert the cell and run a full charge via the camera body or the OEM charger before your first shoot. Some Philips camera BMS systems need one in-body charge cycle to correctly map the new cell's discharge curve to the battery-remaining indicator.

Ni-MH cells have a flatter discharge curve than Li-ion. Philips camera bodies calibrated around a worn original cell often misread a fresh Ni-MH cell as depleted when it still holds significant charge. The indicator is mapped to voltage thresholds, and a new cell at rest sits at a slightly different resting voltage than an aged one. Run one complete charge-to-drain cycle in the camera body and the indicator recalibrates to the new cell's curve.

Flash not fully recycling between shots on a new cell

Flash capacitor recharge draws a sharp current spike — higher than continuous shooting load. If the cell terminals have not been conditioned after sitting in storage, internal resistance stays temporarily elevated and the capacitor recharge current sags before each shot. This shows as longer-than-expected flash recycle gaps even on a fully charged cell. Run two to three full charge-discharge cycles through the camera body and recheck — resting terminal resistance drops as the cell conditions, and flash recycle returns to normal speed.
