Compatible replacement battery

This Cameron Sino battery replaces the Icom BP-166, CM-166 and CM-166S packs used in the IC-A22, IC-A22E, IC-A3 and IC-A3E two-way radios. It supplies 12.0 V and 1000 mAh capacity in a lithium-ion cell. The pack measures 73.76 x 57.10 x 35.80 mm and weighs 250.0 g. It is built to the original specifications with a fully decoded chip.

Voltage and capacity constraints

The radio requires a 12.0 V supply; this pack delivers exactly that voltage and 1000 mAh capacity. A new battery reaches its best performance after two or three complete charge and discharge cycles. Using a low-quality third-party charger will shorten the battery's life. Do not disassemble the pack or expose it to fire or water.

1000 mAh capacity decides suitability

The 1000 mAh rating determines how long the radio operates between charges. If your application demands longer run time than this capacity provides, this pack will not meet the need. Verify the part number on your original battery matches BP-166, CM-166 or CM-166S before purchase.
