Leica BP-DC14-E V-LUX 50 Replacement Battery 3.7V 770mAh

Leica V-LUX 50 / C — 3.7V Li-ion Replacement Battery (BP-DC14-E)

This is a 3.7V, 770mAh Li-ion cell that replaces the BP-DC14-E in the Leica V-LUX 50 and Leica C compact cameras. It slots into the same battery bay as the original and connects through the same three-contact interface. Capacity matches the OEM spec at 2.85Wh.

• V-LUX 50 and C compatibility: Both cameras share the BP-DC14 form factor and the same voltage rail. The cell dimensions — 40.18 × 34.20 × 6.90mm — must match precisely for the door latch and contacts to seat correctly. This cell meets those physical tolerances.
• Bench tested on actual hardware: We cycled this cell through the V-LUX 50 body and an OEM-spec charger. The BMS accepted the cell after one full charge cycle completed from within the camera body. Charge termination and voltage cutoff behaved within normal parameters.
• First charge in the camera body: Charge this cell once through the camera body before heavy use. The V-LUX 50 BMS maps its battery-remaining display against a discharge curve it builds during that first in-body cycle. Skipping this step causes the indicator to read inaccurately for the first several sessions.

Why the V-LUX 50 battery indicator jumps erratically after fitting a new cell

The V-LUX 50 tracks remaining charge using voltage thresholds mapped to the original cell's discharge curve. A new cell discharges at slightly different voltage steps, especially early in its life before it has been broken in. The camera's indicator reads those voltage points against the wrong part of its internal map, which causes the percentage to skip or drop suddenly. Run two full charge-discharge cycles through the camera body and the display will stabilise.

Shot count lower than expected when using continuous AF and the EVF together

Rated shot counts are measured under CIPA conditions, which use the optical viewfinder and limit autofocus cycles. On the V-LUX 50, running continuous AF alongside the electronic viewfinder adds a sustained draw that the CIPA figure does not reflect. The EVF panel and the AF motor together pull current well above standby levels between frames. To extend your count between charges, switch to single-shot AF and use the rear LCD when reviewing shots.
