I used to have a Red top in my rx7, worked good. That one has a home in my dune buggy. Now I have a yellow top in my fd. They are more expen$ive than most other batteries but you get what you pay for.

According to all the guys at the Car Audio shop I used to work at they're all teh same. The extra cost of the yellow is a longer warranty or something and you don't really need it. Just get a red top. $110 is the price around here. I have a red top in my FB.

Red tops are awesome, I just checked mine that's been sitting outside (in the car, tho) for 10 months. It's still fully charged and hasn't lost any cold-cranking amps yet to speak of, and it's around 30 degrees here every night these days.

Yeah mine sat for about 8 months and didnt loose its charge.



they are also very easy to bring back if they do.
