Two-pack lithium-ion batteries for handheld radios

The Kastar MX990 pack supplies two 3.7 V 1900 mAh lithium-ion cells rated at 7.03 Wh each. They are built as direct replacements for the BP-244 battery used in Icom, Baofeng, Dynascan, Intek, IWATSU, Maas, SystemGear, Verizon and YAESU handheld transceivers. Integrated protection guards against over-charge, over-discharge, over-voltage, over-current and over-heating.

Upgrade from worn or lower-capacity BP-244 cells

Swapping to this pair makes sense when the original packs no longer hold a full shift’s charge or when extended field use demands longer run time between recharges. The higher 1900 mAh rating delivers more talk and standby time than aged or lower-rated alternatives, reducing the need to carry spare cells during prolonged operations.

Verify model and charger compatibility before

Confirm that your radio lists the BP-244 part number or appears in the supported equipment list covering Icom IC-RX7, Baofeng UV-100, UV-200, UV-3R, UV-3R Mark 2, Dynascan AD-09, Intek KT-950EE, LN-950, IWATSU DC-PS8, Maas AHT-7, SystemGear MET-1000 series, Verizon UV-X4 and YAESU VR-160, VX-1, VX-2, VX-2E, VX-2R, VX-3. Ensure your existing charger accepts 3.7 V lithium-ion chemistry.

Questions about this item

What battery compartment size fits the 3 by 2 by 2 inch dimensions of each MX990 cell?

Each battery measures three inches by two inches by two inches, so the radio’s battery cavity must accommodate at least that footprint and depth.

How do you install the MX990 pack and what step is often missed?

Slide the pack into the radio until the latch clicks, then charge fully before first use — skipping the initial full charge is the common mistake.

When should the MX990 batteries be replaced based on their 1900mAh capacity?

Replace them when run time drops noticeably below the original 1900mAh rating or after several hundred charge cycles.
