About this replacement
Leica T (Typ 701) — 7.2V Li-ion Replacement Battery (BP-DC13)
This is a 7.2V, 900mAh Li-ion cell built to the BP-DC13 spec. It fits the Leica T mirrorless camera, including the T (Typ 701), T Digital Camera, and Silver 19800 variants. Slot it into the grip compartment the same way the original installs.
- T-series body compatibility: All T-series variants listed share the same grip cavity, contact layout, and 7.2V voltage rail. The BMS handshake protocol is identical across these bodies, so one cell works across the range without modification.
- Bench tested on actual hardware: We cycled this cell through the Leica T body and monitored BMS communication, charge acceptance, and discharge curve. The cell held within expected voltage thresholds across full charge and draw cycles, and the body accepted it without rejection errors.
- First-cycle charge via camera body: Insert the new cell and charge it through the Leica T body itself before your first shoot. The Leica T calibrates its battery-remaining display during an in-body charge cycle — skipping this step can cause the indicator to read inaccurately until the cycle completes.
Why the Leica T battery percentage jumps erratically on a new cell
The Leica T maps its battery indicator to a specific discharge curve profile stored in the body firmware. A new cell has a slightly different initial discharge slope than a well-cycled original, so the indicator can jump — dropping from 80% to 40% suddenly, or holding at one level longer than expected. This is not a fault in the cell. Run one full charge-to-discharge cycle through the camera body and the indicator mapping settles against the actual cell curve.
Leica T showing dead battery indicator on a replacement cell with charge remaining
Some Leica T bodies will display a low-battery or dead-battery warning when a replacement cell's resting voltage sits just below the body's detection threshold after storage. This happens because Li-ion cells self-discharge during transit and storage. Before assuming a fault, place the cell in the camera and connect the body to charge — most units recover once the cell climbs above 7.0V. If the body still shows no battery after a 15-minute charge attempt, try a direct external charger compatible with BP-DC13 to bring the cell up to 7.2V first.
