So here's the deal. Yesterday when I went to start the truck, the
batteries were dead. The charger
said they were at 49% charged. They did take a charge and started the
truck easily several times
since.

However, they are four year-old WalMart batteries, so I'm thinking I
should replace them. You've
praised AGM batteries in the past. Sears has these:

The guy will sell them to me for $176.99 plus $40 installation (which I
could do myself if I didn't
want to help Trump's employment numbers). And, being ex-military, he'll
give me another 10% off. So
I could get them for about $160 each.

Thoughts? I could get the non-AGM's for about $40 less each. Are AGM's
worth the extra bucks?


Take the truck to the battery place that checks batteries. I had one take
down the good battery. Unfortunately I had Walmart replace the battery
while in Twin Falls, ID. Get home few days later and truck has low
battery. They replaced the good battery, not the 2011 batt. As to the
AGM, I think in our trucks, not worth it. Does the truck alternator charge
them properly?
