LifeTec LT41856 Compatible Battery 3.7V 1050mAh Li-ion

LifeTec LT41856 — 3.7V Li-ion Replacement Battery

This 3.7V 1050mAh Li-ion cell replaces the original battery in the LifeTec LT41856 digital camera. It slots into the same battery compartment and connects via the original contacts. Voltage and capacity match the factory spec: 3.7V, 1050mAh (3.89Wh).

• LT41856 compatibility: The LT41856 draws through a standard single-cell Li-ion rail at 3.7V nominal. This cell matches that voltage profile and the physical footprint — 53.20 x 35.30 x 7.10mm — so the compartment door closes without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on bench equipment. The BMS reached full charge without fault flags and held voltage above 3.5V through the bulk of the discharge curve.
• First charge cycle on the LT41856: Run the first full charge inside the camera body or OEM charger before heavy shooting. Some camera BMS firmware needs one complete charge cycle from within the camera to calibrate the battery-remaining indicator to the new cell's discharge curve.

Dead battery indicator on the LT41856 with a partially charged replacement cell

The LT41856's battery gauge maps voltage thresholds to percentage steps. A new third-party cell has a slightly different discharge curve than the factory cell, so the camera can misread voltage and display empty before the cell is actually flat. This usually resolves after one or two full charge-discharge cycles, which trains the camera's fuel gauge logic. If the indicator still reads dead at a resting voltage above 3.6V, pull the battery, reinsert it, and let the camera re-sample the open-circuit voltage from scratch.

Battery percentage jumping erratically during a shoot

This happens when the camera's voltage-to-percentage lookup table doesn't line up with the new cell's actual discharge curve. The indicator can jump from 60% to 20% in a single burst-shot sequence, then recover slightly at idle. It's a gauge calibration issue, not a faulty cell. Run two full charge cycles — charging to cutoff and shooting until the camera powers down — and the percentage steps will stabilise at the correct voltage thresholds.
