Replacement Battery for 3M TAC Headsets

This lithium-ion cell replaces the original power pack in 3M TAC300, TAC300-OTH and TAC500 wireless headsets. It delivers 900 mAh at 3.7 V for 3.33 Wh of capacity. A fully decoded chip ensures the headset recognises the battery exactly like the factory unit. The pack measures 51.75 x 36.70 x 13.36 mm and weighs 30.4 g.

Low Self-Discharge Chemistry

Lithium-ion construction holds charge during standby with minimal self-discharge, so the headset is ready after weeks in storage. Normal operation stays well within the 60 °C upper storage limit, and the integrated protection circuit guards against over-charge, over-discharge, over-voltage and short circuits. No active cooling is required and the cell runs silently.

Drop-In Fit for Existing Chassis

The battery slides into the headset's original compartment without modification and connects via the stock connector. Its 51.75 x 36.70 x 13.36 mm footprint matches the OEM cavity, freeing no extra space but also demanding none. Installation videos are widely available for guidance. Not suitable for headsets outside the TAC300/500 series or for devices requiring a different voltage or form factor.

Questions about this item

How do I install this battery in my 3M TAC300 headset, and what step is often missed?

Slide the battery into the compartment, then ensure the connector is fully seated; a loose plug is the step most often missed.

What maintenance will this 900mAh lithium-ion cell need over its life?

Run two or three full charge and discharge cycles when new, then avoid low-quality chargers to preserve capacity.

At what temperature does sustained use become unsafe for this 3.7V pack?

Do not store or operate the battery above 60 °C (140 °F); exceeding that limit risks permanent damage.
