Or test it yourself with a CCA ir tester. That's what i do. My 17' battery was tested a week ago or so now with a 410cca capacity out of 525cca rated. That's pretty good for over 5 years old. I also tested my 11 year old battery in my Steiner 420 and it's still good as well. I've been waiting for it to die. Maybe it'll last 20 years ? lol (i doubt it) But, i do rejuvenate it with my CTek charger a couple times a year. Just put the Ctek on my Ridgeline since I'm not driving it for the next two weeks as I have a rental car to drive instead for work for a few weeks (or longer).
