the yellow top is not marketed as a starter battery ( like the red top) but it has 750 CCA, I know of friends that have used the yellow top for their starter baeries and have had no problems, one in a 94 yukon V8, another in a 95 cavalier Z24 another in a nissan truck,

so you won't have a problem running the yellow top as a starter battery

THANX RANDOMTASK THAT HELPS, I'M BUYING IT TODAY SO I HAD TO MAKE A CHOICE, I DON'T KNOW WHY PEOPLE THINK THAT EVEN $160 IS ALOT FOR A GOOOOG BATTERY? A REGUALOR ONE COSTS AROUND $60-$80 AND THIS WILL LAST TWICE *** LONG.

I personally use a red top. It is a great all around battery! The yellow top is a deep cycle and was designed for RV use, it is a great battery in that it can be deep cycled(discharged), charged back up and run time after time after time. . .

red tops are made for starting so they are primarily designed to give out the 800 CCA's for 30 secs, they don't discharge evenly after that , starter batteries are not made to be discharged more than 20% of their full capacity.

every time you discharge more than that, the lead plates calcify a bit, until you kill it in a couple a months

red tops are a bad application for car audio

The red top is a quick discharge, the yellow is a slow discharge.

As long as the Yellow Top has enough CCA's it doesn't really matter which battery you use. It doesn't matter if it discharges past 20% or not. If it ever actually gets that low, you'll have bigger problems-- like starting your car.

"starter batteries are not made to be discharged more than 20% of their full capacity" Discharging farther than 20% is not really likely in this application. If it ever actually gets that low, you'll have bigger problems-- like starting your car.

I have a Yellow Top under my hood and that is the only battery I have. I don't have any problems with starting because the Yellow Top still has more cca than my stock battery.

I use a red top as a starter battery, and I finally got my 2 yellow tops to run my system. It really doesnt mater as long as you have enough Cold Cranking Amps.

This topic comes up about 2ce a month. Everyone things that 700 or 750 is not enough. Check your stock batt. Mine is 435 CCA. Now, thats pretty said compaired to the 750 off a yellow top. And I never had a prob starting my car with only 435. With a mmats d300 and a 500 watt ppi for highs.

YELLOW, YELLOW, YELLOW. Go to Optima's web site and all they recommend for car audio applications is the Yellow Top Deep Cycle battery. They explain this somewhat in detail on their site and it makes perfect sense.

Right. Well, my car has the original 13 year old battery with 1100 CCA. Still works great, just keep the juice filled!

Skipp, why do you say that the battery won't be discharged more than 20% ? if it is hooked up to a big amp it will drain it more than 20%, it will totall drain it. leaving it at 12 V. or less
