Kastar MX990 4-Pack Li-Ion Batteries

This four-pack supplies 3.7 V lithium-ion cells rated at 1900 mAh and 7.03 Wh each. They replace BP-244 type packs in Icom, Baofeng, Dynascan, Intek, IWATSU, Maas, SystemGear, Verizon and YAESU handheld radios such as the IC-RX7, UV-100, UV-200, UV-3R series, AD-09, KT-950EE, LN-950, DC-PS8, AHT-7, MET-1000, UV-X4, VR-160 and VX models.

BP-244 form factor and 3.7 V chemistry

The cells match the physical BP-244 footprint and nominal voltage, so they fit the listed equipment without modification. They cannot be used in devices that require a different voltage, a different connector layout or a larger capacity pack than 7.03 Wh.

7.03 Wh per cell for extended runtime

Each battery delivers 7.03 Wh, giving noticeably longer operating time than lower-capacity replacements during typical transmit or receive cycles. Heavy users running continuous high-power transmission will still need spare packs for all-day coverage.

Questions about this item

Should I pick the four-pack or buy single MX990 batteries?

The four-pack gives you four 1900 mAh cells ready for rotation, so a spare is always charged while one powers your radio.

What does 1900 mAh at 3.7 V actually deliver in my handset?

It supplies 7.03 Wh, which typically runs a compatible transceiver for several hours of mixed transmit and receive before needing a recharge.

Does the MX990 use a standard BP-244 interface?

Yes, it replaces the BP-244 form factor and fits the listed Icom, Baofeng, Yaesu and other models without modification.
