Which red top optima battery fits better? The 34/78 or 35 series? This is for a 12 GT500. Thanks.

I know someone posted not too long ago Optima was going to have a battery soon that will fit and provided a link but, at the time, it wasn’t available yet.

Interesting, I was able to get the 35 series redtop optima to fit. It was a little taller than the stock battery, but i was able to adjust the cables accordingly to make it fit. Thanks for the info!

From what I remember Zee, the Optima was about an inch taller. My main fear was it shorting against the hood in an accident or even somebody stupid sitting on it (this happened on another forum). That said, I ran it for 8 years or so, but when Odyssey finally made an AGM that fit, it was a no brainer to me. The bigger Optima did have slightly better specs though.

I'll get you a pic tomorrow, but it definitely fit. I had to pull the positive battery cable wire a bit, but the negative cable fit with no issue. If I remember correctly, the Optima is an inch or so taller than oem.
