Loewe H801 Camera Replacement Battery 6V 2100mAh Ni-MH

Loewe H801 / H811 / PROF180 Series — 6V Ni-MH Replacement Battery

This is a 6V, 2100mAh Ni-MH replacement battery for the Loewe H801, H811, PROF180, PROF185, and compatible models. It restores power to the camera body for image capture and full operation. Dimensions are 88.95 × 47.55 × 20.73mm — verify your original cell matches before ordering.

• H801 / H811 / PROF-series compatibility: These models share the same battery bay geometry, 6V supply rail, and connector orientation. The BMS in each body draws from the same voltage threshold range, so one cell spec covers the group without modification.
• Bench tested on actual hardware: We cycled this cell through the camera's BMS and confirmed stable voltage delivery across the full discharge curve. The BMS accepted the cell without error flags and held the charge-remaining signal steady through discharge.
• First-cycle initialisation on camera bodies: Run the first full charge cycle through the camera body itself, not a third-party charger. Some Loewe bodies need to see a managed charge from within the camera to map the new cell's discharge curve accurately — skipping this can cause the battery indicator to read incorrectly from the first shot.

Ni-MH cells have a flatter discharge curve than lithium chemistries. The Loewe body's indicator thresholds were calibrated around that curve, but a new cell fresh out of packaging may sit at a resting voltage the BMS reads as low. The fix is a full charge cycle completed inside the camera body — this lets the BMS log the cell's actual voltage floor and ceiling. After one full cycle, the indicator should track accurately.

Battery percentage jumping erratically during a shoot

This happens when the camera body maps its indicator against a discharge curve it has not yet calibrated to the new cell. The BMS samples voltage at intervals and translates that to a percentage — if the reference points are off, the display jumps. Run two full charge-discharge cycles through the camera body. After the second cycle, the BMS recalibrates its reference map and the percentage reading stabilises. If it still jumps after two cycles, check resting voltage on a multimeter — a healthy charged cell should read at or above 6.0V.
