Leica NP-80 Digilux Zoom Replacement Battery 3.7V 1400mAh

Leica Digilux Zoom — 3.7V Li-ion Replacement Battery (NP-80)

This 3.7V, 1400mAh Li-ion cell replaces the NP-80 battery in the Leica Digilux Zoom compact digital camera. It powers the image sensor, processing board, and LCD display through the full shooting session. Dimensions are 55.50 × 20.00 × 20.30mm — same physical footprint as the original cell.

• Digilux Zoom fit: The Digilux Zoom runs a single-cell 3.7V rail feeding both image processing and LCD backlight. The NP-80 form factor locks into the original battery door without modification, and the contact spacing matches the camera's three-pin connector exactly.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Digilux Zoom body. The BMS accepted the cell without fault codes, voltage held steady across the processing load, and charge termination triggered cleanly at full capacity.
• First-use charge cycle on the Digilux Zoom: Insert the new cell and charge it fully inside the camera body or OEM charger before your first shoot. The Digilux Zoom's battery-remaining indicator calibrates its percentage thresholds against the first charge cycle — skipping this step causes inaccurate level readings.

The Digilux Zoom maps its battery indicator to fixed voltage thresholds set during the original cell's calibration. A new cell with a slightly different discharge curve can read as empty at voltages the camera wasn't expecting to see that low. This isn't a fault with the replacement — it's a threshold mismatch. One full charge-discharge cycle inside the camera body re-anchors the indicator to the new cell's curve. After that cycle, the display tracks correctly through normal use.

Battery percentage jumping or skipping levels mid-shoot

Erratic percentage jumps happen when the camera's voltage-to-percentage mapping doesn't match the new cell's discharge slope. Li-ion cells from different production batches discharge at slightly different rates in the mid-range, which confuses a fixed lookup table. Run the cell down to the camera's auto-shutoff point, then charge it to 100% in the camera body without interruption. After that full cycle the indicator stabilises — if jumps persist, check that the battery contacts in the door are clean and making firm contact at all three pins.
