Direct replacement for Icom aviation radios

The Estry IC-A22 battery replaces the original BP-166, CM-166 and CM-166S packs used in Icom IC-A22, IC-A3, IC-A22E and IC-A3E transceivers. It supplies 12.0V and 1000mAh capacity in a Ni-MH chemistry built to the same electrical specification as the factory unit. Pilots and ground crews can install it without adapters or wiring changes.

Ni-MH chemistry limits charge speed and storage life

Nickel-metal-hydride cells self-discharge faster than lithium types and require a full charge cycle before first use. The pack delivers 12.0Wh total energy, so operating time depends on transmit duty cycle and squelch settings. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are integrated, but the chemistry still demands proper charging equipment and periodic cycling.

Rugged moulded housing fits existing battery slots

Dimensions of 73.76 x 57.1 x 35.8mm and a weight of 320.0g match the original pack profile, ensuring secure latching in the radio's battery compartment. The case carries ISO9001, RoHS, CE, UN38.3 and MSDS certification marks, confirming compliance with transport and substance restrictions. Buyers needing a lighter lithium alternative or higher capacity for extended shifts should look elsewhere.

Questions about this item

How do I know this 12.0V 1000mAh pack replaces my BP-166 or CM-166S?

The listing confirms direct replacement for part numbers BP-166, CM-166S and CM-166 across models IC-A22, IC-A3, IC-A22E and IC-A3E; match the part number on your original battery to be certain.

What runtime can I expect from the 12.0Wh rating in my radio?

At 12.0Wh the pack stores roughly 12 watt-hours of energy; actual operating time depends on your radio's transmit power, receive duty cycle and display brightness.

Does the Ni-MH chemistry limit charging current or voltage compared with lithium packs?

The 12.0V Ni-MH pack requires a charger designed for nickel-metal-hydride chemistry; using a lithium-ion charger can cause over-voltage and damage the cells.
