Compatible Replacement Battery

This lithium-polymer battery replaces Plantronics part numbers 202555-01 and 211425-01. It fits Savi 8210 and W8210 wireless headsets. The pack delivers 3.7V and 510mAh capacity in a black housing. Condition is new and 100% OEM compatible.

Capacity and Form Factor

Rated at 1.89Wh, the cell measures 39.00 x 20.20 x 6.00 mm. The 0.51 Ah capacity suits the original headset power envelope. No larger or higher-capacity version is offered in this form factor. Buyers who need longer talk time per charge cannot use this part.

Direct OEM Swap

This unit replaces the original battery without modification when the existing pack reaches end of life. The jump is worth it when the headset no longer holds a charge through a normal shift. It is not a capacity upgrade and does not add features.
