Canon BP-110 Legria HF R26 Replacement Battery 3.7V 950mAh

Canon Legria HF R26 / Vixia HF R20 Series — 3.7V Li-ion Replacement Battery (BP-110)

This is a 3.7V, 950mAh (3.52Wh) Li-ion replacement for the Canon BP-110 battery. It fits the Legria HF R26, HF R28, HF R206, Vixia HF R20, and eight additional Canon compact HD camcorder models. The cell matches the original voltage rail and connector footprint of the BP-110.

• Legria HF R and Vixia HF R platform compatibility: These camcorder models share the same BP-110 battery bay geometry, 3.7V supply rail, and BMS handshake protocol — which is why one cell covers the full range. Swapping between models in this group requires no adapter or wiring change.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Legria HF R-series body. The BMS accepted the cell without rejection, current draw through the sensor and processor stages stayed within spec, and protection circuitry tripped correctly at low-voltage cutoff.
• First charge cycle on the HF R26: On first install, run one full charge cycle through the Canon OEM charger or the camera body itself before shooting. The Legria HF R BMS uses that initial cycle to map the new cell's discharge curve — skipping it can cause the battery-remaining indicator to read inaccurately for the first several uses.

Canon BMS authentication rejecting a BP-110 replacement on first install

The Legria HF R series runs a handshake between the body and battery on power-up. A new third-party cell without a prior charge history can fail this check and display a battery warning or simply not power the body. The fix is straightforward: seat the battery, connect the OEM charger, and run a full charge to 100% before attempting to power on. After that first charge, the BMS logs the cell and the rejection stops.

Battery percentage jumping erratically on the Legria HF R26 display

This happens when the camera's voltage-threshold table — calibrated to the original BP-110 discharge curve — maps incorrectly onto a replacement cell with a slightly different curve shape. The indicator may jump from 80% to 40% or stall at a fixed percentage for an extended period. Run two to three full charge-discharge cycles through the camera body to let the BMS recalibrate. After conditioning, the display should track within a few percentage points of actual remaining charge, and voltage at full charge should read approximately 4.2V.
