Re: Will not start
Yea, buy one tomorrow.
I liked my SuperStart 48-72 from O'Reilly's. It meets the specs, but is a 'cheapie', was $85 back in 2010. I buy cheap batteries that meet the specs, and replace them every three or four years - I know others spend $185 and try to get 7 years out of them but I prefer to have a new battery in my car.
This is nothing new, I've been like this for 35 years.
Most others here will recommend much better batteries, you can search the tech threads or just use the search box for "Battery" and see what you get. Keep the terminals clean and make sure you investigate what the ground bolt looks like - mine only had 44,000 on it when I got it and the ground lug/bolt was AWFUL.
