Do not buy an Optima. Ihey are nothing but junk. I have replaced four of them for people that had nothing but problems out of them & Optima well not do a thing about them. They will not hold a charge if you don't drive the car every day. I have one in my 73 firebird & it has only started it a few times I have to charge it every time. It will be replaced by a wet cell befoer I drive it again. Junk Junk Junk
