HP C200W Digital Camera Replacement Battery 3.7V 1050mAh

HP C200W — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1050mAh Li-ion replacement battery for the HP C200W digital camera. It slots into the same battery compartment as the original cell and powers the camera for photo and video capture. Use the Capacity figure from the product data — 1050mAh / 3.89Wh — when comparing against what the camera originally shipped with.

• HP C200W fit: The C200W runs a single-cell Li-ion pack at 3.7V nominal. The connector pinout and physical dimensions — 43.30 x 31.30 x 7.10mm — match the OEM bay directly. No adapters, no trimming.
• Bench tested on actual hardware: We ran charge and discharge cycles through the cell and confirmed the BMS responds correctly to the camera body's charge-termination signal. Charge acceptance and cutoff voltage both sat within expected range.
• First-cycle initialisation on the C200W: Complete one full charge via the camera body or OEM charger before heavy shooting. Some HP camera BMS firmware needs that first cycle to map the new cell's discharge curve — without it, the battery-remaining indicator can read inaccurately from the start.

Dead battery indicator showing on a partially charged replacement cell

The C200W's fuel gauge maps remaining charge against a voltage-threshold table calibrated to the original cell's discharge curve. A fresh replacement cell hasn't been profiled yet, so the camera can misread its state of charge and flag it as dead even when it's holding voltage. This usually clears after one complete charge-discharge cycle through the camera body. Once the BMS has logged that cycle, the indicator tracks accurately.

Battery percentage jumping erratically during a shoot

Erratic percentage readings happen when the camera's voltage-to-percentage mapping doesn't match the new cell's discharge curve at mid-charge levels. The HP C200W samples terminal voltage at intervals and translates that to a percentage — if the cell discharges slightly differently from the OEM, the reading can jump 20–30% in either direction. This isn't a fault with the cell itself; it's a calibration gap. Run two full charge cycles through the OEM charger and the readings will stabilise as the BMS builds a more accurate profile.
