Optima Battery / Red or Yellow Top, What do you have? Options

[cv7713]

I am going to buy an Optima battery but am unsure which one to get. Is the red top sufficient? I am also installing a 170 amp high output alternator.

What is the difference between to two batteries? Cranking amps?

Do you like yours?

Were talking like 140-200$ batteries here. Where do you guys get the money to buy such expensive batteries.

because optima's are a different kind of battery then a conventional one. They are leak proof and could even be mounted upside down, they don't make any hydrogen emissions which means they won't corrode battery terminals and won't explode if you accidentally get a spark to close to them, they last twice as long, and they are able to make more cold-cranking amps with a smaller battery. only downside is they are a little denser so they have a little more weight to them, but since you're using a smaller battery then the weight probably evens out to what you would expect a conventional battery with 800 CCA to weigh.

anyway, yellow top is a deep-cycle battery which means it's more durable to being drained and then recharged. which would be good if you plan on using your stereo while the car isn't running.
