Ive had my red top for 5 years no problems...
I've been using a blue optima for about 6 years now and still going strong... Yes yes I know its for marine applications
I used to have a red top optima in my race truck for vibration reasons but for this car I wanted something that would run the compressors (if needed) subs, etc.... while the car wasn't running and still have the balls to kick the motor over for a start. That is why I went with the yellow top, kinda like a deep cycle for your car. You can drain the hell outta it and it will still start your car for you. That and it last two times longer than your conventional battery.
optimas are good. thats what i use
I had the ETX14 in my N/A R32 for over 2 years and only time it really drains down is short starts and stops from the afterrun coolant pumps running for 5 minutes.
I have the DEKA ETX20L it started my car in 15 degree weather... I leave the car off for 3 days out of the week and it starts right up... I've been using it daily for quite a while... it has died on me a few times but it was my fault for leaving the fan on.. I just recharged it and it has been fine.
just had a etx14 sat in car for over a month and started right up.
I liked my old optima. lasted 7 years. I've heard the new ones are Interstate brand now and are no good. I will not buy again based on what I've been hearing. too bad.
I had an optima yellow top in my Jeep for 3 years. Then all of a sudden a cell died without warning, leaving me stranded in the desert when I went to start it. I will never buy another one. The duralast I replaced it with has been in there for about 4 years now with no problems. It also cost less than half what the optima was.
Yellow tops are great, but since they switched the Redtop to the new design, it's a joke.
