About this replacement
Panasonic Lumix DMC-GF2 Series — 7.4V Li-ion Replacement Battery (DMW-BLD10)
This 7.4V, 1050mAh Li-ion battery replaces the DMW-BLD10 in the Panasonic Lumix DMC-GF2 family of compact mirrorless cameras. It fits the GF2, GF2CK, GF2CS, GF2CR, and over 58 additional Lumix variants that share the same battery bay and connector. Physical dimensions are 51.83 × 36.27 × 13.83mm — identical to the original cell.
- GF2 series compatibility: Every model in the DMC-GF2 line uses the same 7.4V battery rail, BLD10-format connector, and BMS handshake protocol. One replacement covers the entire camera variant range without any modification.
- Bench tested on actual hardware: We cycled this cell through the GF2 body and OEM charger. The BMS accepted charge from both, reported accurate state-of-charge after one full cycle, and held voltage above the camera's low-battery cutoff through sustained burst shooting.
- First-use charge cycle for GF2 BMS calibration: Charge this cell fully inside the camera body or OEM charger before your first shoot. The GF2's BMS maps remaining battery percentage against the discharge curve of a fresh cell — skipping this step causes erratic percentage readings from the first frame.
Battery percentage jumping on the GF2 display after fitting a new cell
The GF2 body maps its battery indicator against fixed voltage thresholds calibrated to a known discharge curve. A new replacement cell can have a slightly different internal resistance profile, so the camera misreads mid-discharge voltage and shows erratic percentage jumps. This is a calibration issue, not a faulty battery. Run one complete charge-and-discharge cycle through the camera body — the BMS relearns the curve and percentage display stabilises from the second cycle onward.

Some GF2 bodies trip a low-voltage lockout if they detect cell voltage below 6.0V on first contact — common when a new battery has been sitting in storage at partial charge. The camera refuses to power on and shows a depleted-battery animation. Pull the battery, place it in the OEM charger until the indicator shows a full charge, then reinsert. The body accepts the cell once it reads above the 7.0V threshold on power-up.
