Compatible Battery Replacement

The FYIOGXG lithium-ion pack replaces original batteries FNB-V133Li, FNB-V134Li and FNB-V138Li in Vertex Standard radios VX-261, VX-264, VX-451, EVX-531, EVX-534 and EVX-539. It delivers 1500mAh at 7.4V for 11.10Wh of capacity. Buyers needing a different voltage or connector will not find a match here.

Voltage and Capacity Match

The single specification that decides fit is the 7.4V nominal voltage combined with 1500mAh capacity; the original part numbers AAJ67X001, AAJ68X001 and AAK66X501 share these exact ratings. If your radio requires a different voltage or a higher milliampere-hour rating, this pack will not power it correctly.

Simple Slide-In Installation

The pack slides into the radio battery cavity and locks with the existing latch; no tools or soldering are required. The most common issue is ordering the wrong variant, so verify the model number and original part number on your old battery before purchasing. The physical dimensions are 110.90 x 57.80 x 32.20 mm and the weight is 283.0g.

Questions about this item

How long will the 1500mAh capacity last in my radio?

Runtime depends on transmit power and duty cycle; the 11.10Wh rating gives a baseline for estimating operating time.

Does the 7.4V Li-ion pack charge in the original desktop charger?

Yes, it matches the FNB-V133Li and FNB-V134Li part numbers used by the listed Vertex Standard models.

Will the 110.90 x 57.80 x 32.20 mm case fit the battery compartment?

Those dimensions match the OEM FNB-V133Li and FNB-V134Li packs for the VX-261, VX-264, VX-451, EVX-531, EVX-534 and EVX-539.
