Drivers side battery STEAMING.... Causing no starts etc
Well i kept having intermittent weak starts and sometimes a dead battery in the morning. Well i went to mess with it again today, and the batteries were dead as a doornail, and wouldnt take a charge, swapped another battery in, got her running, let it charge for a bit, turned it off, it started right back up strongly. Left for a ride an hour later it started (weak), went to get some food, it was idling high when i left it set at taco bell. Went home, was running fine, was making 13.5-14.3 v during ride- got home and we kept smelling this PEUTRID smell, we smelt it at taco bell too, well this time i knew it was the truck since it was coming through the vents, popped the hood and the drivers battery was F'n STEAMING.... like high pressure steam coming out! I moved away from that bastard quick, since a buddy that was with me said his bosses 08 f250 (he bought used with unknown miles) had his drivers battery explode, literally EXPLODE, (also a motorcraft like mine)... and warned me this was about to happen to mine. It didnt, luckily, but needless to say, that battery is toast..... now the ?s.
1. Charging system seems ok from minimaxx readout, and the fact that the other good battery keeps a charge short term and does re start the truck after sitting a few minutes, is there any way i can test otherwise other than auto zones/auto parts store test?
2. Has anyone seen this happen and WHAT THE HELL causes a battery to steam!?!?
3. The truck has ~32k miles, and is still under 3/36 warranty- although i seriously doubt it, would this be covered?
