Re: What color Optima battery do I buy for my a2 GTI???? (hybrid gti 2)
yellow is deep cycle red is standard blue is for marine? applications.
deep cycle is only better for applications were the battery is going to be drained down and charged back up again a lot. for exaple cars that are in storage alot, rv's, motorcycles ect.
for normal car appliations the standard red top is probably best. i have a yellow top cause i used to live downtown and walk everywhere plus we have the three cars so the car only got driven once a month or so for a long time.
you do have to modify your batt tray to get them to fit right also. nothing major.
