Good luck on that one. Most only last a little over 2. I had to replace both this fall. A word of advice replace as a set.Are you sure? Because I thought these batteries are suppose to last longer than 3 yrs.
Just an update. Swap out the old batteries and truck works fine now i guess that was the problem. Voltage on old battery tested fine but i guess it was just to old. I bought the Kirkland brand from Costco w/850 crank start $75 each.Thanks guys for all your help.:thumbsup:AC Delco makes some real good ones. I believe they are 850 CCA. Check yours first unless you already did. Let us know if that is your problem. How many miles are on your truck? Thay fall under the 3/36 warranty.
