Replacement battery for Panasonic Attune II HD3

This lithium-ion pack replaces the Panasonic WX-SB100 cell used in the Attune II HD3, WX-CH455, WX-ST100 and WX-ST300 wireless headsets. It supplies 700 mAh at 3.70 V and is sold as a single unit for owners who need a fresh power source.

Built to original dimensions with safety protections

The cell measures 40.00 x 31.10 x 5.90 mm and weighs 40 g, matching the factory footprint so it seats without modification. A decoded chip communicates with the headset exactly like the original, while over-charge, over-discharge, over-voltage and short-circuit circuits guard the pack during daily use.

Verify the part number before ordering

Confirm your headset shows the WX-SB100 part number on the original battery label; other Panasonic models use different cells. The new pack reaches full capacity after two or three complete charge cycles, and the supplier advises against low-quality third-party chargers.

Questions about this item

What voltage does the 700 mAh lithium-ion cell supply to the Panasonic Attune II HD3?

The battery delivers 3.70 V, which is the standard nominal voltage for a single lithium-ion cell in this headset.

Will the 40.00 × 31.10 × 5.90 mm pack fit the WX-ST100 battery compartment?

Yes, those are the exact dimensions of the original WX-SB100 pack, so it slots into the Attune II HD3, WX-CH455, WX-ST100 and WX-ST300 without modification.

Which way round does the connector go when fitting the replacement pack?

Align the polarity tabs on the plug with the socket — forcing it backwards is the common mistake that bends pins and prevents charging.
