Replacement battery for IC-M31 and compatible models

The Estry IC-IC-M31 is a 7.2V 1800mAh Ni-MH replacement pack built to the same specifications as the original BP-224 and BP-224H cells. It fits the IC-IC-M31, IC-M32, IC-IC-M2A and IC-M21 radios and includes overcharge, over-discharge, over-voltage and short-circuit protection. The pack measures 122.1 x 58.42 x 19.7mm and weighs 327.8g.

Who this suits and who should look elsewhere

This pack suits owners of the listed Icom radios who need a direct voltage and capacity match with certified safety compliance. It does not suit users who require a different voltage, a higher capacity than 1800mAh, or a chemistry other than Ni-MH.

Deciding specification: 7.2V 1800mAh Ni-MH chemistry

The single specification that decides fitment is the 7.2V 1800mAh Ni-MH rating, which must match the original battery exactly for the radio to operate correctly. Confirm the model number and part number BP-224 or BP-224H before ordering.

Questions about this item

How often will the 1800mAh Ni-MH pack need replacing under normal use?

The pack is rated for one year of service; plan on a replacement after roughly twelve months of regular charge cycles.

What capacity limit appears first during extended transmit sessions?

The 1800mAh capacity sets the runtime ceiling; once those milliampere-hours are depleted the radio loses power.

Does the 327.8g battery get hot or draw extra current when the radio runs all day?

Built-in over-voltage and short-circuit protection limits heat and current, so the pack stays within safe thermal limits during continuous operation.
