KingSener FNB-V104LI laptop battery 2200mAh 7.4V

Compatible Vertex VX231 radio power

This 7.4 V lithium-ion pack is built as a direct replacement for the Vertex VX231 two-way radio. It supplies 2200 mAh of capacity and fits the original battery compartment without modification. The pack is intended for operators who need a fresh, reliable power source for daily communication duties.

Capacity and runtime headroom

At 2200 mAh the cell delivers enough energy for extended talk and standby periods in typical dispatch or field work. Heavy transmit cycles or continuous high-power use will drain the pack faster, so users running long shifts should plan for a spare or mid-day recharge. The chemistry holds its rated capacity when cycled correctly.

Build quality and daily handling

The battery uses a black Li-ion casing with integrated protection circuitry to guard against overcharge and short circuits. Its form factor matches the original unit exactly, so it clicks into the radio and charger without force or alignment issues. Proper storage above 80 % charge during downtime helps preserve long-term health.
