Sennheiser OfficeRunner Battery Replacement 2-Pack

When a wireless headset starts dying mid-call, the problem is almost always a worn-out rechargeable battery. The Sennheiser OfficeRunner Battery Replacement 2-Pack provides a straightforward fix with genuine OEM Li-Polymer cells rated at 205mAh — the same specification as the originals. Because these are authentic Sennheiser components, you avoid the fit and compatibility issues that can arise with generic alternatives, and you can be confident the battery management circuitry in your headset will work as intended.

The two-pack format is a practical touch: swap one battery in immediately and keep the second as a ready spare for when capacity eventually degrades again. Installation is a simple drop-in process — no tools, no disassembly beyond the battery compartment. These cells are compatible with a broad range of Sennheiser professional headsets including the OfficeRunner, DW Office, DW Pro1, DW Pro2, SD Office, SD Pro1, SD Pro2, and MB Pro series, making them a versatile stock item for offices running multiple Sennheiser models.
