Replacement Battery and Charger Kit

The Kastar MX990 kit supplies a 3.7 V lithium-ion battery rated at 1900 mAh and a matching AC wall charger. It replaces the original power pack for Maas AHT-7, SystemGear MET-1000, Verizon UV-X4 and several Yaesu VX series radios. One charger and one battery are included in the pack.

Foldable Plug Charger With LED Status

The charger accepts 100 to 240 V AC at 50 to 60 Hz and delivers 4.2 V DC at 600 mA. A red LED shows active charging while a green LED signals standby or full charge. The foldable flat plug reduces bulk when the unit is stored or transported.

Direct Drop-in For Listed Handheld Radios

No extra cables or adapters are required; the battery fits the compartment of each named device and the charger plugs straight into a wall outlet. The compact 3 by 2 by 2 inch form factor leaves room in a gear bag for other accessories. Buyers needing multiple spare cells or a multi-bay charging station will need a different solution.

Questions about this item

How do I install the battery and charger, and what step do people often miss?

Insert the 1900mAh Li-Ion battery into the compatible device, then plug the charger's foldable flat pin into a 100~240V AC outlet; the red LED shows charging, green means full. People often forget to unfold the flat plug fully before inserting it into the wall socket.

What maintenance or replacement will the MX990 battery need later?

The 7.03 Wh lithium-ion cell will gradually lose capacity over charge cycles; plan to replace the battery pack when run-time drops below your needs. The charger itself has no user-serviceable parts and requires no routine maintenance beyond keeping the foldable pins clean.

What limit appears first during sustained charging use?

The charger outputs 4.2V at 600mA, so the 1900mAh battery reaches full charge in roughly three hours; sustained use is limited by this fixed charge rate and the battery's 3.7V nominal voltage.
