2014 silverdo 1500 5.3, I need a battery. Does it have a h7 agm or a h7 dgl,? What is the difference ? Other then about 50 more for the dgl, thanks

First if you merely go to any store (except maybe Walmart) that sales batteries, they take your car info and then provide you with the correct battery, (choices would be the grade or quality of the battery)

CA and CCA are the main numbers you really need to be concerned about.

One of the most-commonly asked questions we hear relates to what "AGM" means on battery chargers. The short answer is that AGM stands for "Absorbed Glass Mat," which is a specific type of lead-acid battery. OPTIMA Batteries are considered SPIRALCELL AGM batteries.

So is the agm battery worth the xtra money $50.00 over the dgl battery? Tks

The only battery worth a darn in my experience is a Sears Diehard. Best warranty and replacement policy around and the match it for you. Go with the Gold series.
