Panasonic DMW-BLG10 Lumix DMC-GF6 Replacement Battery 7.4V 980mAh

Panasonic Lumix DMC-GF6 / GX7 — 7.4V Li-ion Replacement Battery (DMW-BLG10)

This is a 7.4V, 980mAh Li-ion replacement for the Panasonic DMW-BLG10 battery. It fits the Lumix DMC-GF6, GF6K, GF6R, GX7, and over 22 additional Lumix bodies that share the same OEM battery slot. Drop it in and it draws power through the same connector and BMS handshake as the original cell.

• GF6 and GX7 compatibility: Both cameras run on the same 7.4V nominal rail with an identical battery bay footprint and BMS communication protocol. The DMW-BLG10 form factor — 42.10 × 37.00 × 14.10mm — is shared across this Lumix cluster, which is why one cell fits all listed models.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a GX7 body. The BMS accepted the cell, fuel gauge populated correctly after one full charge cycle, and protection circuits triggered at expected voltage thresholds.
• First-use charge cycle on GF6 and GX7 bodies: Run the first full charge from within the camera body or OEM charger before heavy shooting. Some Lumix BMS firmware requires an in-body charge cycle to correctly map the new cell's discharge curve to the battery-remaining indicator.

Flash recycling slowing down mid-shoot on a fresh DMW-BLG10 cell

The GF6 and GX7 bodies draw heavily on the battery during flash capacitor recharge — often 1.5–2A in short bursts. As the cell ages or sits discharged, internal resistance rises and voltage sags during those recharge bursts. The camera body interprets this sag as a low-battery condition and throttles flash recycling speed before the indicator drops significantly. If recycling time noticeably lengthens before the battery gauge reads low, the cell is no longer holding voltage under load.

Battery percentage jumping erratically on the GF6 display

This happens when the camera's BMS hasn't yet mapped the new cell's discharge curve. The Lumix fuel gauge uses stored voltage-threshold tables calibrated during a full charge cycle. A new cell installed without completing that cycle shows percentage readings that jump — often dropping 20% suddenly, then recovering. Run one uninterrupted charge to 100% in the camera body or OEM charger, then discharge through normal shooting. After that cycle, the gauge stabilises and reads within a few percent of actual charge state.
