Thats not saying if you can get 1000 cold cranking amp battery that fits, doesent mean you should. 800 is more than enough, when approacing 1000,plates get thinner so they can fit more. I get more life out of a 750 or 850 than a 1000 cca battery. Sold,tested,installed 1000+batteries.
Been thinking about replacing my battery too, gets really weak when colder, afraid i may smoke the starter if i keep this up.
