Replacement battery for Lightspeed headsets

This lithium-ion cell replaces the original power pack in Lightspeed A500, Aviation and Tango headsets. It matches the factory voltage of 3.7 V and delivers a rated capacity of 1050 mAh. Built-in circuitry guards against overcharge, over-discharge, over-voltage and short circuits. The pack is certified to ISO 9001, RoHS, CE, UN 38.3 and MSDS standards.

Who should buy this and who should not

Pilots and headset owners whose existing pack carries part number 806-00001-000 will find a direct fit. Users of other headset brands or different Lightspeed models should look elsewhere because the connector and dimensions are specific to the listed units. The single-pack format also means buyers needing multiple spares must order additional units separately.

Critical specification for compatibility

The decisive figure is the 1050 mAh capacity at 3.7 V packed into a 54.92 x 33.94 x 6.0 mm case that weighs 50.0 g. Only batteries sharing these exact electrical and physical parameters will seat correctly and power the headset for the intended duration.
