battery issues
I have owned my truck for 2 1/2 years now. Since then I have been through two sets of interstates and now on my second set of Walmart brand. What could be killing my batteries? Stock stereo,no extra lights,no winch,new terminals,grounds are good n clean. It's not costing me anything except embarrassment when my girl won't start. Any clues???

As mentioned, have your alternator checked for output amperage & voltage...then with the key out of the ignition...take a multi-meter and check all fuses to see if any are remaining hot when the truck is turned off (if one side is hot, then check the other side of the fuse). When you find the hot one (showing voltage in and out of the fuse) you will know the circuit responsible for drawing the batteries down (given that your alternator is working correctly).

Alt is new and charging well,along with the starter being new. Checked fuses already checks ok. Maybe just a bad batch of batteries??? Who knows. Double checking everything now.

Have you tried just giving the batteries a good charge via a charger(not just driving it around)I had 2 new interstates a year old that I thought were going bad and come to find out they just needed a good charge.All was well after that and that was the dead of winter in ct...An easy way to check if batteries are good or bad is to get a hydrometer and pop the covers off each cell on batteries and check the specific gravity.Thats how I found my interstates were still good but needed a charge...
