A 'charge error' message may appear on some radios after a charge cycle is complete. Just because the aftermarket 80li battery with the chips may not be fully identified by VX-5/R or VX-6/R or VX-7/R radio. But it is still work in the radio and not affect the funtion. While if you do mind this issue or find any inconvenience during the using process, please feel free to look for other alternative battery, or contact the Amazon customer service for the return/refund.
