Four-pack replacement for Panasonic DMW-BLK22

This Kastar set supplies four 7.2V lithium-ion batteries rated at 2200mAh and 15.8Wh each. They are built as direct replacements for the Panasonic DMW-BLK22 and work with the DMW-BTC15 charger. The pack targets photographers using the Lumix DC-S5 or DC-S5KK mirrorless cameras who want spare power for long shooting days.

Upgrade from single OEM battery or aged cells

Swapping a lone original battery for this four-pack removes the need to recharge mid-session and replaces cells that have lost capacity over time. The jump is worth it when you regularly shoot video, time-lapse or bursts that drain a single pack before the day ends. Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating protection circuits certified to UL1642 and CE standards.

Drop-in fit with the original charger

Installation is a simple battery swap; the packs slot into the camera and the DMW-BTC15 charger exactly like the OEM units. The main risk is mixing depleted and fresh cells in a multi-bay charger, which can confuse the charge-termination logic. Keeping the four batteries together as a matched set and labelling them avoids that issue.

Questions about this item

What physical dimensions should I check to ensure these 3*2*3 Inch batteries fit my Panasonic Lumix DC-S5?

Each battery measures 3 by 2 by 3 inches, matching the original DMW-BLK22 form factor for the Lumix DC-S5 and DC-S5KK mirrorless bodies.

How do I install the four batteries using the Panasonic DMW-BTC15 charger, and what step is often missed?

Insert each 7.2V 2200mAh pack into the DMW-BTC15 charger slots; the step users miss is waiting for the charger’s indicator to confirm full charge before first use.

When will the built-in protection circuit (UL1642 & CE) need the battery pack replaced?

The over-charge, over-discharge, over-voltage, over-current and over-heating circuit extends cycle life; replace a pack when runtime drops noticeably below the rated 15.8 Wh capacity.
