Replacement battery for Icom IC-M23 and IC-M24

This Cameron Sino BP-266 lithium-ion pack replaces the original battery in Icom IC-M23 and IC-M24 marine two-way radios. It supplies 3.7 volts and 1500 mAh capacity for handheld communication on the water. The pack is sold new and carries ISO9001, RoHS and CE certification.

Decisive specification: 3.7 V 1500 mAh lithium-ion

The single figure that determines fit is the 3.7 volt 1500 mAh lithium-ion chemistry matching the original BP-266 part number. If your radio requires a different voltage or capacity this pack will not work. Buyers who need a higher capacity or a different form factor should look elsewhere.

Straightforward swap with a few cautions

Installation consists of removing the old pack and clipping the new one into the radio battery compartment; many users find online videos helpful. Ensure the connector seats fully before closing the latch. A new pack reaches full performance after two or three complete charge cycles. Do not disassemble, expose to fire or water, or store above 60 °C.

Questions about this item

How long will the 1500 mAh capacity keep my IC-M23 or IC-M24 transmitting on the water?

The 1500 mAh lithium-ion cell stores 5.55 Wh at 3.7 V, matching the original BP-266 rating so run-time mirrors the factory pack.

What connector standard does the BP-266 replacement use and does it limit charging speed?

It uses the same OEM connector as the Icom BP-266; the built-in protection chip handles charge control exactly like the original battery.

Will the 55.55 x 40.09 x 8.70 mm pack fit the battery compartment and latch securely?

Dimensions and 35 g weight are identical to the genuine BP-266, so it slides into the IC-M23 and IC-M24 cavity and locks without modification.
