OPTIMA Yellow Top batteries, featuring Spiralcell Technology, are designed for all of your deep cycle needs. It's perfect for people who are serious about sound. OPTIMA's power is cleaner with higher voltage output than conventional batteries. You can play your system louder and longer. And they have a greater cycle life so they can be drained and recharged more often.

hi guys,
I got a red top optima batt installed few weeks ago, reason I choose red top is to match my velocity red RX8, it runs well but dun feel the difference but it gives me peace of mind and not worry about maintenance. Do check out the pics. Cheers.

My Red Top seems to spin the engine up faster. It was obvious on the first twist of the key. Now I'm used to it.
I did need a new battery connector and a little extra cable to make the hook-up possible. I liked the Costo price of the 75/35 size Red Top and it felt lighter than the standard Yellow Top.

"Deep Discharge" lead acid batteries are designed to withstand this type of treatment. Their life will still be shortened, but not by much. They are not very good at high current discharge. It can damage them, and shorten their life. I'm talking a discharge current number equal to or greater than the battery amp/hr rating. For a battery found in an RX-7 or RX-8, that would be a current greater than 50-70 Amps. To draw that starting a rotary, the temp. would have to be below about -20 C (or about 0 F), or you'd have to have very heavy oil in there.
The Optima Yellow top is this type of battery.

I think the original post in that regard, underestimated the Yellow-Top's suitability as a starting battery. It has plenty of CCA for most climates and should start your car fine at 20F regardless of your choice of oil.
