I've always had good luck with DieHard. I have an Interstate in my truck that has been good. I've wasted money on two or three Optimas.
 
Put a redtop in mine in 2004, 10 years later still starts no problem. I always keep it on a tender when not using it, and drive about 4k a year. However same as others have said it looks as if their rep has gone down hill over the last 5+ years, just from reading the stuff online id probably replace mine with an interstate or sears die hard etc..I agree with the others...don't over think it.
 
If you've ever had a battery explode on you then you will never buy a wet cell again. I have Optima red tops in the fast cars, two yellow tops in my Ram Cummins, and an Interstate in the Bimmer. They all work flawlessly but the true test is the yellow tops starting the Cummins in single digit temps without skipping a beat. Again, to hell with wet cell batteries.
 
if you care about dropping any unsprung weight i have been running an Odessey P980 for over 2 years now...its only 25 lbs and cranks my raised compression gen 3 over just as fast as my 48lb yellowtop optima did...plus you can mount them anywhere you want and turn it sideways or upside down....it doesn't matter like a lead acid battery does.

Just a side note....i was able to crank over my motor with a Hawker P680 which checks in at 15lbs when the weather was warm and ran it in the summer for a while. I do feel it was a little undersized....but neverless it did fire up.....so for a track option in the summer you could drop nearly 35lbs for a track day if needed off the rear of the car. Thats alot of unsprung weight. my stock battery was 40lbs.
 
Bitter cold winter here and my car has been in the garage since October. My Interstate fired the car right up last Saturday. No battery tender.

I believe The battery would be sprung weight... but I agree with your thinking. Great place to shed some pounds especially on the track car.
 
Unsprung weight refers to anything that does the same job but can be replaced with a lighter part...sprung weight would be any part of the car that you need like the frame or tranny...and would have to be entirely redesigned to shave weight.

99 percent of everyone would not redesign their frame to shave weight...so it stays put. You then begin to look elsewhere as where to cut weight...that refers to unsprung weight. An A/C compressor...is a great example of unsprung weight...you don't need it for the car to function.

I never ever heard "unsprung weight" defined that way. New one on me.:confused:

You are fucking kidding, right? Unsprung weight is the weight not supported by the suspension (wheels) and sprung weight is the rest. Simple as that.

Mambaviper you just failed sir. The correct definition is what has been linked. Unless you know exactly what you are speaking about dont post like that. Cheers

Gotta be an AE. No car guy is that clueless.
 
The weight reduction that is no longer there is what i was refering to as unsprung....by definition then I would be wrong...didn't realize you guys would loose your fuckin minds..cheers
 
By removing the stereo/amp and then led's throughout and some hid's would then be curious as to what size battery and alternator would actually be required?, dropping down to a 70 amp alternator would free up some ponies and a physically smaller battery would also be lighter as well. I realize CCA is important but most of my starts are above 40 degrees anyway
