I plan on replacing a 4.5 year old OEM group 35 battery in the next 6 mos when I re-tire the car. I don't think the car is very hard on a battery, but the hot climate may be. Ive had good luck with a DieHard Platinum in another vehicle, but that battery was super $$$. Is there a lower cost version available under another name? What is another good battery at maybe half the cost of the Platinum?
