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.
Im running an Odyssey battery in my Corrado. Its new to me so I cant give long term feedback on the battery. But the battery doesnt have any lips on the bottom so it doesnt mount into the stock battery spot. Im still trying to figure out a way to mount it properly. Personally it cranked my car up faster then my old optima ever did. I like it and its got a 3 year warranty.
Same here. Mine is about half the size as Tachy's. Have mine in the spare tire well. No problems, other than giving it a charge when the car sits. I run a 400w amp too.
I have this one (or one very similar to it; forgot the model #). I have a metal sleeve/box that is slides into that is bolted down. Had it for over 3 years and it's still going strong.
optima blue tops are marine-think of blue water and yellow are deep cycle 2] having the ground LARGER than the power is ALWAYS better in terms of car audio- electrons move negitive to postive , if my amp takes a 4 gauge wire for power the ground gets a 2 guage, this alone has gotten rid of some of my dimming
I have had a red top 34R in my R32 for almost 2 years now, no problems at all.
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.
they used to be good but over the last 5 years or so they have dropped in quality. I have purchased 3 red tops and 4 yellow tops for customers and each one failed prematurely.
I compared the dimensions of both batteries (stock vs Optima) and the Optima is shorter, skinnier, but like 1/4 wider. Optima did not fit, or would not fit without modification to the positive terminal. Ordered the OEM from Keffer.
