Optima Red Top
I have had a Optima Red Top for over 5 years now without it dying like conventional lead maintenance free one's. These are very good batteries

No more dimming with stereo use!
Wow, i thought I was going to have to buy a Kinetic cell to go behind my seat in my truck for use with my high power amp, but so far, I have thrown all i got at this battery on my factory Silverado alternator, and No Dimming! Sure this battery costs more, but it comes with a warranty, and it's got all those amps! If you have dimming, or just need a new battery, please consider these batteries. Although the yellow top's are better, the red's should not be taken lightly in any fashion. You will love this thing!

Red top
Best battery I've ever bought. I did have it in my hot rod for two years and that was only started every 3 or 4 months. I never had to charge it or jump start. Very high compression motor. I sold the hot rod and now have it in my daily driver. Worth every penny!

Great battery
Used this as general battery in my car with 1000wrms amp for Kicker 12L7 and 15CVR and ran it for 3 and a half hours with the car off and still cranked up like nothing, could have probably gone for longer. Lights never dimmed either. Never had ANY problems starting car or anything with this battery, got a normal battery now and problems all the time. Lasted me like 5 years. This battery is a beast, though it is more expensive than normal batteries it is well worth it.
