Question I have no power!!!

ok so went out to start the truck a couple of days ago and bam nothing. no battery power. so i charge the batteries and fire the truck up. let it run for about an hour to make sure the alt charged them up good. (this was firday night/saturday morning) went out today (sunday) to start the truck and bam batteries are dead again. so i throw the charger back on and start looking for hot componets cause i figure, if something is drawling power its going to get hot. well i found that the passenger side battery is hotter than the driverside, nothing majorly noticible, but the batter was hotter. so i disconnected the battery and charged just the driver side. fired the truck up tonight and it ran fine (ran it about 20 minutes) so im leaving the passenger side disconnected and letting the truck sit tonight to see if the driverside holds a charge. is there anything else i could look at that may be drawling power? is this something that has happended to anyone else?

btw batteriers for this truck are not cheap, come to think of it nothing for this truck is cheap.

Could have a dead cell in one battery taking out both batteries. Have them load tested, you'll know quickly if it's fried.
