Compatible Vertex radios

This 3400mAh lithium-ion pack replaces the original FNB-V128Li cell in Vertex VX-820, VX-821, VX-824, VX-829, VX-870, VX-920, VX-921, VX-924, VX-929, VX-970, VX-P820 and VX-P920 handsets. It is built to the same physical footprint and connector layout as the factory battery. The replacement restores talk time and standby performance for professional radio users. It is not suited for radios that require a different voltage or connector pinout.

Capacity and voltage

The battery delivers 3400mAh at 3.7V, yielding 25.16Wh of energy storage. This single figure determines whether the pack meets the runtime needs of a specific shift or operation. Buyers who need more capacity per charge should look for a higher-watt-hour alternative. The decoded chip communicates with the radio’s fuel gauge exactly like the original equipment.

Thermal and power behaviour

Normal charging and discharging occur within the 0 to 60 degrees Celsius range specified by the manufacturer. The internal protection circuit guards against overcharge, over-discharge, over-voltage and short-circuit events during daily use. No active cooling is required and the pack operates silently in the handset. Storage above 60 degrees Celsius is not recommended.

Questions about this item

How long will the 3400mAh capacity last in a Vertex VX-820 radio?

The 3400mAh / 25.16Wh rating matches the original FNB-V128Li specification, so runtime in a VX-820 will be equivalent to a new OEM pack under the same transmit/receive duty cycle.

What connector standard does the AAJ62X001 pack use?

It uses the proprietary Vertex two-pin connector found on the VX-820, VX-821, VX-824, VX-829, VX-870, VX-920, VX-921, VX-924, VX-929, VX-970, VX-P820 and VX-P920 models.

Will the 89.60 x 54.90 x 27.60mm case fit the VX-820 battery compartment?

Yes — those are the exact dimensions of the original FNB-V128Li, so the pack seats flush in the VX-820, VX-821, VX-824, VX-829, VX-870, VX-920, VX-921, VX-924, VX-929, VX-970, VX-P820 and VX-P920 housings.
