I went against my better judgement and bought an Optima red battery a month ago. My dad's failed after 2 days. Two friends of mine had bad batteries within the first month. I did a search on here and saw nothing but good results so I bought one anyway. I started the car for the first time, broke in the cam, and shut it off. I started it two more times after that with no trouble. I then had to leave town for a couple weeks so I disconnected the battery. I just got back in town and hooked up the battery. It was so dead the dome light didn't want to work. I unhooked it and put the battery charger on it. It immediately went into protection mode as if I shorted the terminals together. So it looks like this battery is no good after 3 starts. Just a warning for anyone else who might buy one. Right now we're 4 for 4 going bad in the first month on 4 separate cars.
