Replacement Battery for Vertex Standard Radios
This 3350 mAh lithium-polymer pack replaces the original power source for Vertex Standard EVX-531, EVX-534, EVX-539, VX-261, VX-264 and VX-451 portable radios. It matches part numbers AAJ67X001, AAJ68X001, AAK66X501, FNB-V133Li, FNB-V134Li and FNB-V138Li. The unit is new and ships with a fully decoded chip that works like the factory battery. Installers can follow widely available online videos for guidance.
Capacity and Operating Headroom
Rated at 7.4 V and 24.79 Wh, the cell provides extended talk and standby time for daily professional use. The 3350 mAh rating supports typical shift lengths before a recharge is needed. Heavy transmit duty cycles or continuous high-volume audio will deplete the reserve faster, so users running back-to-back transmissions should plan for a mid-shift swap or charger access.
Bundled Protection and Packaging
The pack includes built-in overcharge, over-discharge, over-voltage and short-circuit safeguards that protect both the battery and the radio during faults. A shock-absorbing foam insert cushions the cell during transit, reducing the risk of physical damage before first use. No charging cradle, cable or software utility is supplied with this standalone battery.

Questions about this item
Will the 3350 mAh 7.4 V lithium-polymer battery fit the existing battery compartment of my VX-261 radio?
The pack measures 110.80 x 58.00 x 35.20 mm and weighs 150 g, matching the original dimensions for the VX-261, VX-264, VX-451, EVX-531, EVX-534 and EVX-539 models.
How can I confirm the new battery is functioning correctly after the first charge?
After two or three full charge and discharge cycles the battery reaches its rated 3350 mAh capacity and the fully decoded chip reports charge status to the radio exactly like the original pack.
Does the package include a charger or only the replacement battery?
Only the 3350 mAh 7.4 V lithium-polymer battery is included; a compatible charger for the EVX-531, EVX-534, EVX-539, VX-261, VX-264 or VX-451 must be purchased separately.
