Replacement Battery for Samson Micro AR2

This lithium-ion pack replaces the original power cell in the Samson Micro AR2 receiver and Swar2 Airline system. It matches the OEM part number 1-OTH0157 and fits the specified equipment without modification. The battery arrives new and ready for installation after verifying the device model.

300 mAh Capacity and 1.11 Wh Energy

The cell stores 300 milliampere-hours at 3.7 volts, delivering 1.11 watt-hours for typical wireless receiver operation. Runtime depends on the transmitter duty cycle and audio levels; extended sessions may require a spare unit. The pack weighs 7.0 grams and measures 37.00 by 20.00 by 6.00 millimetres.

Connector and Form Factor Decide Fit

The pack uses the proprietary connector and exact 37.00 by 20.00 by 6.00 millimetre footprint required by the Micro AR2 receiver. Builders whose equipment uses a different pin layout or larger cavity cannot use this cell. Confirm the part number on the original battery before ordering.
