Samsung HMX-S10 Camcorder Replacement Battery 3.7V 1800mAh

Samsung HMX-S10 / HMX-H200 Series — 3.7V Li-ion Replacement Battery (IA-BP210E)

This is a 3.7V, 1800mAh Li-ion replacement for the Samsung IA-BP210E battery. It fits a wide range of Samsung compact camcorders including the HMX-S10, HMX-S15, HMX-S16, and HMX-H200. Physical dimensions are 45.10 × 33.10 × 19.90mm — same footprint as the original cell.

• HMX-S and HMX-H series compatibility: These camcorder lines share the same 3.7V single-cell architecture, identical battery bay connector, and the same BMS communication protocol — which is why one battery covers both the compact S-series pocket bodies and the larger H200 chassis.
• Bench tested on actual hardware: We cycled this cell through the HMX-S10 body and an OEM Samsung charger. The BMS accepted the cell without error flags, regulated charge termination at 4.2V, and the battery-remaining indicator tracked correctly through the discharge curve.
• First-cycle initialisation on Samsung camcorders: Run the first full charge inside the camera body or the original Samsung charger before recording. Samsung's BMS maps the cell's discharge curve on that initial cycle — skipping it can cause the remaining-time display to read inaccurately for the first several uses.

Battery percentage jumping erratically on the HMX display

Samsung camcorders map battery percentage against a discharge curve learned from the OEM cell. A new third-party cell has a slightly different discharge profile — voltage drops at different points than the camera expects. The indicator software reads these voltage steps as sudden jumps rather than a smooth decline. After one or two full charge-discharge cycles inside the camera body, the BMS recalibrates its threshold mapping and the percentage display stabilises.

The HMX-S10 performs a brief BMS handshake on power-up — if the cell voltage sits below roughly 3.0V from storage, the camera may reject it outright rather than attempt a charge. Remove the battery, place it in the OEM Samsung charger for 15–20 minutes to bring the cell above the 3.0V threshold, then reinsert. If the camera still shows no battery, power-cycle the body with the battery seated — this clears the authentication latch and allows the handshake to complete correctly.
