Battery OPTIMA or Deka

optima blue tops are marine-think of blue water and yellow are deep cycle 2] having the ground LARGER than the power is ALWAYS better in terms of car audio- electrons move negitive to postive , if my amp takes a 4 gauge wire for power the ground gets a 2 guage, this alone has gotten rid of some of my dimming

I have had a red top 34R in my R32 for almost 2 years now, no problems at all.

Red Top, 4 years so far. Survived 3 Portland Oregon winters, a few complete drains, and sites for a week + at a time without use. Way to heavy though.

I ran red top for a little more than five years before it ran out of juice, so I bought another a couple years ago

I bought a optima in 2001 and ran it for 6 years no problems, even though i drained it multiple times. I bought a replacement in 2005, exchanged on warrenty in '06, and i'mlooking for a replacement currently. i know optima was bought out a few years ago i wonder if quality has gone down since then.

Unfortunately, I only ran that battery for 10 months.....car was stolen, so I can't say it was great for many years, but in 10 months time, not one hick-up......even when my Autolamps Online HID kit went haywire and turned itself on and stayed on ALL NIGHT.

Prep the car... Prep the space... The new beatzzz Deka Batteries... Clean as can be! Hot damn clean wiring!

have an optima red top it starts the car at -40 weather no problem, only catch is if you kill it the batt will never be the same iv gone through 2 so far in the last 2 years but with 10 year or more warranty who cares.

I had the yellow top in my 97 and It was nothing but problems, I know that doesnt help you answer your questions... Just saying

They are not worth the money, I work at a local auto parts store and have Two Red Top Batteries sitting on my battery pallet waiting to be shipping out and recycled. If that Red top wasn't made in Colorado, it's junk.
