I have replaced my battery 3 times in the last 2 months. This last battery in got seemed to work until I went to start my truck today. I drove it all day Friday, did not drive it yesterday (Saturday) and today I jumped in and it wouldn't start. I cant seem to find anything wrong with the truck. Does anyone know what the problem could be?

My truck isn't that bad, but Mine is original battery in 03 with 5.4 IT seems if I don't drive it more than once a week, the battery is dead. Haven't noticed in the summer at all, but in winter, it's dead in like 5 days without driving! Dead to the point it won't even pop the electronic locks! My 01 Ranger was the same way. My 94 Probe has sat for over two weeks now and fires up no problem!

Have you checked the performance of the alternator?

These trucks sometimes develop leaks in the windshield seal resulting in damage to the GEM unit that's piggybacked to the fuse box. Some symptoms in this are like you described, your battery being drained over night, the blower randomly coming on while the truck is off, the cd player not turning off even though the keys are removed from the ignition, etc.
