Replacement Battery for Panasonic DMW-BLK22

The Koah Pro Battery serves as a direct replacement for the Panasonic DMW-BLK22. It is built for photographers and videographers using compatible Lumix cameras who need a reliable spare power source for extended shoots or travel. Japanese lithium-ion cells provide dependable performance without memory effect. The unit is sold as a single 1.0 count pack.

Voltage and Capacity Rating

This battery is rated at 7.2V and 2250mAh, the key specification that determines whether it matches the original equipment requirements. It is designed to work with the original Panasonic charger or a Koah charger, ensuring straightforward recharging. The lithium-ion chemistry supports consistent output across the charge cycle. Compatibility covers the LUMIX S5, GH5, G9 and GH5s camera bodies.

Runtime and Practical Limits

The 2250mAh capacity delivers a longer run time for typical stills and video sessions, reducing the frequency of battery swaps. It comfortably handles day-long event coverage or location work when paired with a second charged unit. Runtime will diminish in cold conditions or during continuous high-bitrate video recording. The compact 0.9 x 2.4 x 1.8 inch form factor adds minimal weight at 4.8 ounces.

Questions about this item

What does the 2250mAh rating actually deliver in a Lumix S5 or GH5 II?

The 2250mAh capacity at 7.2V provides extended shooting time compared with lower-capacity packs, letting you capture more stills or longer video clips before needing a recharge.

Does the 7.2V lithium-ion cell work with the original Panasonic charger?

Yes, the battery is designed to charge on the standard Panasonic DMW-BLK22 charger as well as on Koah chargers, so no extra charging gear is required.

Will the 0.9 x 2.4 x 1.8 inch pack fit the battery compartment of a Lumix G9 or GH5s?

The dimensions match the OEM DMW-BLK22 form factor, so it seats securely in the S5, GH5 II, G9 and GH5s battery bays without adapters.
