About this replacement
Canon Vixia HF10 / HF100 Series — 7.4V Li-ion Replacement Battery (BP-808)
This is a 7.4V, 890mAh (6.59Wh) Li-ion replacement for the Canon BP-808 battery. It fits the Canon Vixia HF10, HF11, HF100, HG20, and seven additional Vixia-series camcorders that share the same battery bay and connector. Slot it in and the camcorder reads it the same way it reads the original cell.
- Vixia HF and HG series compatibility: Canon grouped these camcorders around the same 7.4V power rail, BP-808 form factor, and BMS handshake protocol. Any model in this cluster draws from the same voltage thresholds and uses the same charge termination logic, so one cell covers the full list.
- Bench tested on actual hardware: We cycled this cell through the Vixia HF10 body and an OEM Canon charger. The BMS accepted the cell without errors, charge termination triggered correctly at capacity, and discharge voltage held above the camcorder's low-battery cutoff through the full cycle.
- First-cycle calibration on Vixia bodies: Run the first full charge inside the OEM Canon charger or the camcorder body itself — not a third-party charger. Some Vixia BMS builds only update the battery-remaining display accurately after seeing a complete charge-discharge cycle through the camera's own charge controller.
Why Vixia camcorders reject a new BP-808 cell on the first install
Canon's Vixia BMS runs an authentication check when it detects a new cell. If the cell's internal resistance or resting voltage sits outside the expected window — common on a freshly shipped battery that hasn't been topped up — the camera may flag it as unreadable. The fix is a full charge via the OEM Canon charger before the first use in the body. One complete charge cycle resets the handshake state and the camcorder recognises the cell normally from that point forward.
Battery percentage jumping erratically on the Vixia display
The Vixia series maps battery percentage to a fixed voltage-threshold table calibrated against the original BP-808 discharge curve. A new replacement cell may have a slightly different mid-discharge voltage profile, causing the indicator to skip steps or jump backward. This is a display calibration issue, not a fault with the cell itself. Run two full charge-discharge cycles through the camcorder body and the indicator will track the new cell's actual curve accurately from around 8.2V down to the 6.8V cutoff.
