Direct Replacement Battery

This 3.7 V lithium-ion cell is built exclusively for the Eartec EVADE headset. It restores the original runtime so crews can stay on comms through a full shift without swapping packs.

Verify Headset Model First

Confirm the headset is an EVADE unit before ordering; the connector and voltage are matched to that model only. No other Eartec or third-party headset is supported by this pack.

Steady Output Over Eight Hours

The chemistry holds a stable 3.7 V across the discharge curve, so audio level and clarity remain constant from the first minute to the last. Field-replaceable design lets users swap cells in seconds during a break.
