I have heard that unless you are running a secondary battery, and running the system with the car off, it is pointless to get a deep cycle battery, like the Optima's.



Are the red and yellow tops mostly hype and is it better to spend the money on a good 84 month interstate, or die hard battery?

You want a starting battery.



Deep cycles are for like boats and rv's with tv's and other electronics.



Optima batteries are a waste of money. And the yellow tops are starting batteries but they are around $150 or higher iirc



I had a napa battery that i bought for $70 lasted me 6years.

The Red Top before this one lasted 5+ years before cranking started slowing down. The current Red Top survived an alternator failure that drained it to below 10V (a death sentence for a regular lead-acid battery). A Yellow Top would have been nice to have, but the Red Top apparently took no harm from the abuse. Starting batteries: good until you REALLY need to be able to discharge the battery!

tbh a generic battery should be fine for most purposes - it seems a bit excessive paying close to $200 for a battery that might last an extra one or two years.

Some people would say it is excessive to spend $4k on a turbo setup to double your engine's power output. To each his own, and to my car a Red Top.

If you don't need extended run time then just buy a standard battery. They can last for over 10 yrs if maintained properly. Keep the water level where it's supposed to be and recharge the battery with a charger once in a while.

haha, 10 years that's rich. In San Diego maybe. Someplace it actually gets hot and/or cold for several months every year, and the car is regularly started in those conditions, not so much.
