My truck is about 4 1/2 years old with about 51k miles. It still has the original battery. I'm thinking it might be gettin close by next year to replace it. What is a good replacement battery for it. I have added a few electronic's on it by the way, so I might need a little more powerful one.

 

I had an advanced auto silver battery in for 2 years and just had it warranty swapped out to a gold (850cca I think). I usually get most of my parts from autozone but when dead batteries pop up advanced auto has usually been closer, and after I bought the gold battery I called the store I bought the first battery from for the warranty info and dropped off my core and got about $60 back with no hassles, even though I upgraded to a bigger battery. Surprisingly good service.

 

My truck is 8+ years old (build date 7/2/03) and nearly 114K. Still the OEM battery. Starts on "the first kick". When it goes, I'll get an Interstate battery from Costco.
