Replacement battery for Sennheiser headsets

The Cameron Sino lithium polymer cell delivers 180 milliampere-hours at 3.70 volts and fits a wide range of Sennheiser wireless headsets including the MB Pro 2, OfficeRunner, Pro 1, Pro 2, SD Office, SD Office ML, SD Pro1, SD Pro1 ML, SD Pro2 and SD Pro2 ML. It carries ISO 9001, RoHS and CE certification and includes a fully decoded chip that works like the original battery. Overcharge, over-discharge, over-voltage and short-circuit protection are built in.

Compact polymer pack with wired connector

The pack measures 37.00 by 17.70 by 4.77 millimetres and weighs 30 grams, using a lithium polymer chemistry rated at 0.67 watt-hours. A wired connector plugs directly into the headset's internal socket, so no soldering is required. The package includes shock-absorbing foam for transit protection and the manufacturer notes that installation videos are widely available online.

Verify model and part number before ordering

Check the model number on your headset and the part number on your original battery against the compatibility list and part numbers 504374 or BATT-03. Ensure the connector orientation matches your device when installing. A new cell reaches its best performance after two or three full charge and discharge cycles. Avoid low-quality third-party chargers and do not store the battery above 60 degrees Celsius or 140 degrees Fahrenheit.

Questions about this item

What voltage does the 180mAh lithium-polymer cell deliver?

The cell supplies 3.70 V, which is the standard nominal voltage for single-cell lithium-polymer chemistry used in these headsets.

Will the 37.00 x 17.70 x 4.77 mm pack fit my headset's battery compartment?

Those are the exact outside dimensions; compare them with the space inside your specific model before ordering.

Which step do installers most often miss when fitting the replacement?

Fully seating the connector so the decoded chip communicates with the headset; a loose plug prevents charging and capacity reporting.
