Kastar LI-42B 4-Pack Camera Batteries

Each unit delivers 3.7V and 1400mAh for extended talk time. The pack suits operations that run multiple headsets across shifts and want a ready supply of spares.

Check Headset Model Before Ordering

Verify that your headset is listed among the compatible Panasonic Attune, Attune 3020, Attune 3050, Attune I, Attune II, Attune II HD3, WX-CH455, WX-SB100 or WX-ST100 models. The batteries are not suited for other camera or headset families. Confirm the voltage and form factor match the original equipment specification.

Safe Operation With Built-In Protection

Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating circuits and meets UL1642 and CE safety standards. The lithium-ion chemistry runs cool during normal headset use and holds its rated 5.18 Wh capacity across charge cycles. No special cooling or maintenance is required.
