I didn't test them but they just seemed fine, but now in the process of working on they are toast. Charging them now. When i got to my truck this morning to put my tools in the back the remote worked again. Gonna have to wait and see once the batteries are charged up. lets hope that was it and nothing else too major. After this, and replacing the ball joints and a hub assembly in the last month I would take a lot of pleasure out of shooting it right now.
