Reviews of OPTIMA parts For Business

I used to have a red top optima in my race truck for vibration reasons but for this car I wanted something that would run the compressors (if needed) subs, etc.... while the car wasn't running and still have the balls to kick the motor over for a start. That is why I went with the yellow top, kinda like a deep cycle for your car. You can drain the hell outta it and it will still start your car for you. That and it last two times longer than your conventional battery.

optimas are good. thats what i use

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.

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.

they used to be good but over the last 5 years or so they have dropped in quality. I have purchased 3 red tops and 4 yellow tops for customers and each one failed prematurely.

I compared the dimensions of both batteries (stock vs Optima) and the Optima is shorter, skinnier, but like 1/4 wider. Optima did not fit, or would not fit without modification to the positive terminal. Ordered the OEM from Keffer.
