Replacement battery for two-way radios

The Kastar MX990 is a lithium-ion cell rated at 1900mAh and 7.03 Wh. It replaces the BP-244 pack used in Icom, Baofeng, Dynascan, Intek, IWATSU, Maas, SystemGear, Verizon and YAESU handheld transceivers. The single-unit pack fits the IC-RX7, UV-100, UV-200, UV-3R series, AD-09, KT-950EE, LN-950, DC-PS8, AHT-7, MET-1000 models, UV-X4, VR-160, VX-1, VX-2, VX-2E, VX-2R and VX-3 radios. It is not for devices that require a different form factor or voltage.

Thermals and power draw

The 3.7V chemistry delivers a nominal 7.03 Wh from a compact 3 by 2 by 1 inch housing. Built-in protection guards against over-charge, over-discharge, over-voltage, over-current and over-heating during normal transmit and receive cycles. The cell meets UL1642 and CE safety standards for stable operation. No active cooling is required in typical handheld use.

What the protection circuit changes

Integrated safeguards extend cycle life by preventing the stress events that degrade lithium-ion cells prematurely. This reduces the frequency of replacements and keeps the radio ready for extended field sessions. The pack ships as a single battery without a charger or additional accessories.

Questions about this item

How do I install the Kastar MX990 battery into my Icom IC-RX7 without damaging the contacts?

Power off the radio, slide the battery into the compartment until the latch clicks, and ensure the three gold contacts align with the device terminals. The step users miss is verifying the 3.7 V label faces outward before locking it in.

What maintenance will the MX990 Li-Ion 1900mAh pack need after a year of daily charging?

No scheduled maintenance is required. Store at roughly half charge if unused for months, keep contacts clean, and replace the pack once run-time drops noticeably below the original 7.03 Wh rating.

At what point does the MX990 hit its thermal limit during continuous transmit on a Yaesu VX-2R?

The built-in over-heating protection circuit interrupts output when internal temperature exceeds the safety threshold, which typically occurs during prolonged high-power transmit sessions on compatible radios like the VX-2R.
