Four-battery pack with foldable AC charger

This set includes four lithium-ion cells rated at 7.2 V and 2200 mAh each, plus a compact wall charger with a foldable flat plug. It is built for photographers who need reliable spare power for the Panasonic Lumix DC-S5 and DC-S5KK mirrorless cameras. The bundle replaces the original DMW-BLK22 battery and DMW-BTC15 charger in a single purchase.

Drop-in power for Lumix S5 bodies

Each cell matches the 15.8 Wh capacity of the factory battery, so it fits the camera’s battery compartment without modification. The charger accepts 100 to 240 V at 50 to 60 Hz and delivers 8.4 V at 600 mA, letting you recharge from any standard outlet worldwide. No extra cables or adapters are required to start charging.

LED status and foldable plug simplify travel

A red LED shows active charging and a green LED signals standby or full charge, removing guesswork during overnight top-ups. The foldable flat plug reduces bulk in a gear bag and protects the prongs from bending. Photographers who need simultaneous multi-bay charging or USB-C input will not find those features here.

Questions about this item

How long will the 2200 mAh batteries last under continuous shooting before they need recharging?

Each 2200 mAh cell stores 15.8 Wh at 7.2 V; run time depends on the camera’s power draw.

Does the charger become noisy or hot when left plugged in all day?

The wall charger has no fan and runs silently; it draws up to 600 mA at 8.4 V, so heat stays low.

Which Panasonic camera bodies work with these batteries without an adapter?

The pack is compatible with Lumix DC-S5 and DC-S5KK mirrorless cameras.
