Kastar MX990 1900mAh Li-Ion replacement

The Kastar MX990 is a 3.7 V lithium-ion battery rated at 1900 mAh and 7.03 Wh. It replaces the BP-244 pack in Icom, Baofeng, Dynascan, Intek, IWATSU, Maas, SystemGear, Verizon and YAESU handheld radios. The single-cell unit ships new and includes built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection.

Capacity and headroom for radio use

At 1900 mAh the pack delivers extended transmit time on compatible UV-100, UV-200, UV-3R, VX-1, VX-2 and IC-RX7 models. Heavy-duty cycles or continuous high-power TX will deplete the cell faster, so operators running long shifts should carry a spare. The 7.03 Wh rating sets the practical energy ceiling for each charge.

Thermals, noise and power draw

Lithium-ion chemistry runs silently with no moving parts, so the battery adds no audible noise during receive or transmit. Internal protection circuitry limits current and temperature, keeping the cell within safe limits under normal radio loads. The pack draws only the power the radio requests, with no parasitic drain when idle.

Questions about this item

Will the Kastar MX990 work in my Icom IC-RX7 alongside the original BP-244?

Yes, the MX990 replaces the BP-244 in the Icom IC-RX7 and matches the 3.7V 1900mAh specification so the radio sees the same voltage and capacity.

How can I verify the MX990 is performing correctly after the first charge?

The built-in protection circuit prevents over-charge, over-discharge, over-voltage, over-current and over-heating; a full charge should deliver 7.03 Wh and the radio’s battery indicator will show normal runtime.

Does the pack include a charger or only the MX990 battery?

The listing is a 1-pack of the MX990 Li-Ion cell itself; a compatible charger for the BP-244 form factor must be sourced separately.
