Rollei RCP-8325X Replacement Battery 3.7V 1050mAh

Rollei RCP-8325X / Movieline DV5 Series — 3.7V Li-ion Replacement Battery

This 3.7V, 1050mAh Li-ion battery fits the Rollei RCP-8325X, RCP-10325X, Movieline DV5, and Movieline P3 compact cameras. It slots into the same battery compartment as the original cell and connects via the same three-contact terminal. Dimensions are 53.20 × 35.30 × 7.10mm — confirm these match your camera before ordering.

• Cross-model fit — RCP and Movieline platforms: The RCP-8325X, RCP-10325X, Movieline DV5, and Movieline P3 share the same battery bay geometry and voltage rail at 3.7V nominal. One cell covers all listed models because the BMS expects the same charge curve across the platform.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on compatible Rollei bodies. The BMS completed full handshake, accepted charge via both USB-input charger and in-body charging where supported, and held voltage within spec across the discharge curve.
• First-install charge cycle on Rollei compact bodies: Before shooting, run one full charge cycle directly in the camera body or the original Rollei charger. Rollei compact camera firmware maps the battery-remaining indicator against a charge profile — skipping this step can cause the indicator to read inaccurately from the first shot.

Rollei compact camera bodies store a learned discharge curve from the previous cell. When a new cell goes in, the firmware compares current voltage against old calibration data and can flag the battery as flat even when it holds a genuine charge. This is a calibration mismatch, not a faulty cell. Insert the replacement and charge it fully in the camera body — the firmware recalibrates against the new cell's curve during that first charge session. After one complete cycle, the indicator should track accurately from 4.2V down.

This happens when the camera's voltage-threshold map doesn't yet align with the new cell's actual discharge curve. The indicator samples terminal voltage at fixed intervals — if the new cell drops voltage faster or slower at a given state of charge than the original, the readout skips steps or jumps backwards. It's not a capacity defect. Run two full charge-discharge cycles in the camera body and the indicator's sampling points will re-anchor to the real curve. After that, readings stabilise and step down smoothly.
