Capacity and Chemistry Limits

The Li-Polymer cell delivers 3.7V and 240mAh for 0.89Wh of energy. Runtime depends on the headset's power draw and the battery's age; capacity will decline with charge cycles and storage conditions.

Direct Solder Installation Required

The pack measures 36.62 x 26.70 x 7.60 mm and connects via solder tabs, not a plug. Installation needs soldering skill and correct polarity alignment; improper handling can damage the cell or headset electronics.
