Key Features

• Compatibility: Designed to replace the original battery in a range of Vertex and YAESU compatible radios, which reduces the time spent searching for an exact OEM part.

Who It's For

This battery is best for radio users who own one of the compatible Vertex or YAESU models (EVX-231, EVX-261, EVX-530, EVX-531, EVX-534, EVX-539, VX-260, VX-261, VX-451, VX-454, VX-456, VX-459) and who need a dependable replacement that restores original run time.
