@SpyderMike posted:I put a really light and small LiFePO4 Deltran (Battery Tender) BTL24A480CW battery in my Spyder just recently. It was much smaller than the Odyssey PC680 it replaced. It's dimensions are 6.89 X 3.43 X 5.12. It comes with rubber shims so that you can use it in larger battery mounts. It weighs only 4lbs. Cranks like a mutha...480CCA.
I also use the same setup in my 1985 911 and it does that car well too. No problem starting it.
Isn't modern technology cool! I could cut 35 pounds out of my car just with that battery. And if I then removed the spare tire my car would be be lighter than Danny's. Then I'd only need 50 more horsepower to challenge him!
