About this replacement
Canon DC210 / DC220 / DC230 Series — 7.4V Li-ion Replacement Battery (BP-208)
This is a 7.4V, 850mAh Li-ion replacement for the Canon BP-208 battery. It fits the DC210, DC220, DC230, DC10, and over 19 additional Canon camcorder models that share the same battery slot and connector. Voltage and cell chemistry match OEM spec exactly.
- DC-series camcorder compatibility: These Canon camcorders share a common 7.4V battery platform with the same physical connector and BMS communication protocol. A cell that fits one will fit the others without modification or adapter.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on a DC-series body and monitored BMS handshake, charge acceptance, and cutoff voltage. The cell charged fully, held voltage through playback load, and tripped the low-voltage cutoff cleanly.
- Camcorder BMS initialisation on first use: On first install, run one full charge cycle through the Canon OEM charger or directly in the camcorder body. Some Canon BMS firmware only maps the discharge curve to the battery-remaining indicator after completing an initial charge cycle inside the camera body itself.
Canon BMS rejecting the BP-208 replacement on first install
Canon DC-series camcorders run a battery authentication check on power-up. A new third-party cell can fail this check and display a "change the battery pack" warning even when the cell is fully charged. This happens because the BMS hasn't yet completed a handshake cycle with the new cell. Insert the battery, place the camcorder on charge via the OEM charger, and allow one complete charge cycle before powering on — this typically resolves the rejection at 8.4V full charge.
Battery percentage jumping erratically during recording
Canon's battery indicator maps display percentages to specific voltage thresholds calibrated against the original BP-208 discharge curve. A replacement cell with a slightly different discharge profile can cause the percentage to jump — dropping from 60% to 20% without warning, or holding at a fixed number then cutting off suddenly. This is a calibration mismatch, not a faulty cell. Run two or three full charge-discharge cycles through the camcorder body and the BMS will re-map its thresholds against the new cell's actual curve.
