Who this suits and who should look elsewhere

Buyers needing a direct replacement for a depleted Mitel headset battery will find the correct fit and voltage here. Technicians who value safety certifications can rely on the ISO9001, RoHS and CE markings. Users whose headset model is not in the supported list must source a different part.

Deciding specification: 240mAh capacity

The 240mAh rating determines whether this cell matches the runtime of the original battery. Verify the part number on your existing pack against 50005711 or 50006764 before ordering. A mismatch in capacity or voltage will cause incorrect operation.

Questions about this item

How can I confirm the 240mAh battery is working correctly after installing it in my Mitel 6863i headset?

After fitting the battery, charge it fully then complete two or three full charge and discharge cycles; the headset should hold a call for the expected talk time and the battery indicator will track capacity normally.

What comes in the package and is anything else needed to fit the 3.7V 240mAh cell into a Mitel 6920 handset?

The box contains one Cameron Sino lithium-ion cell weighing 5.8g with dimensions 36.70 x 20.68 x 4.30mm; no extra parts or tools are required beyond the handset itself.

My original Mitel battery shows part number 50006764 — does this 240mAh 0.89Wh version replace it directly?

Yes, the cell matches both Mitel part numbers 50005711 and 50006764 and is listed for every model from the 6863i through the 6970, so it is a direct replacement.
