Great battery replacement for my radio.
My OEM battery lasted a while, but would start to die part of the way through the day. This replacement battery has great life. I'm still at a full charge at the end of the day.

battery life
bought this battery Mar 22 , 2025 got battery in timely manner. I use this battery maybe twice a month , and drain it until light flashes red on radio, and I fully recharge it. Put it on charger and went to work, came back and the charger was flashing red indicating possible bad battery. tried using it and got maybe an hr worth of use before radio flashed red. tried charging again and got same red flashing light. Not happy this battery lasted less than 4 months
