Hey guys, I'm going to be buying a new battery for the vert. I'm going to be getting a Optima. Now I'm trying to figure out the diff between the yellow top and the red top. And honestly I can't tell the diff. They say the yellow one is meant for cars with after market audio systems. And then the red on is a deep cycle that last twice as lond as a regular batt... can someone explain the diff between these two?

Thanks

Jay

A deep-cycle lead-acid battery is designed to deliver a consistent voltage as the battery discharges. In contrast, starter batteries (e.g. most automotive batteries) are designed to deliver sporadic current spikes. Battery-driven vehicles, such as golf carts, forklifts and floor sweepers commonly use deep-cycle batteries. While a deep-cycle battery can be used as a starting battery (and may work better than a traditional starting battery with the myriad of electronic components attached to most modern vehicles), the lower "cranking amps" imply that an over-sized battery may need to be used in an older vehicle that lacks fuel injection. Deep cycle batteries can be charged with a lower current than regular batteries.

The key structural difference between deep cycle batteries and cranking batteries are the lead plates, which are solid in deep-cycle batteries and composed of porous sponge-like plates in starting batteries. Some batteries that are labelled "deep-cycle" do not possess these solid lead plates, however, and are actually "hybrid" batteries. While a deep-cycle battery is designed to discharge down to as much as 20% of its charge capacity over several cycles, companies recommend that a hybrid battery not be discharged beyond 50% of its capacity

I've heard that since Interstate has bought out Optima they're not as good anymore...

I've heard that just using the cheapest costco battery that fits your car is the best option. Oh wait, that's what I do, and I never worry about all that fancy battery business. If it holds it's charge for a weekend that's all I care.

Walmart does carry them. Kind of expensive. Look at the manufacturing date on the battery.

^^Thanks Guys! Yeah I'll defenatly be checking the manufacturing date on the batt! I was hoping to get it at costco as I heard they were cheaper!

Sam's club carries them as well. Way cheaper than buying them at Walmart. I think it was 40% cheaper at Sam's. Even if u don't have a membership paying the 10% extra is still worth it.
