I asked for specific battery grease from both Volvo, Mercedes-Benz, auto parts near home that sold me the batteries of my cars. They just gave me generic grease, like CV joints. This morning with the engine cold, I had my wife start the engine 3 times. I made a video. No problem today. Yesterday, however, he did not want to leave.
