Direct replacement for 3M TAC headsets

This lithium-ion battery is built for the 3M TAC300, TAC300-OTH and TAC500 wireless headsets. It delivers a 3.70 V, 900 mAh cell rated at 3.33 Wh, matching the original specifications. Workers who rely on these headsets for daily communication can swap the pack without tools and restore factory run-time.

Replaces the original pack when capacity fades

The unit fits the same compartment and connector as the ALPHA1100 part supplied with the headset. When talk time drops noticeably or the headset fails to hold a charge through a full shift, this cell restores the original energy reserve. It is not suited for other 3M models or third-party headsets that use a different form factor or voltage.

Steady output through a full shift

The 900 mAh chemistry maintains a consistent 3.70 V supply during continuous transmit and receive cycles. Self-discharge is low when the headset sits idle between shifts, so the pack is ready without a top-up charge. Extended storage at full charge will gradually reduce capacity, so store at partial charge if the headset will be unused for weeks.
