Interesting read- had same issue once with the passenger side battery on my '01 Dmax. Never had a battery problem and all of a sudden, I couldn't start the truck one day after work. Got a jump and later smelled battery acid- passenger side battery was hotter than a pistol! Both had the foam wrap. Replaced with DieHard equivalents and never had another issue. Maybe location and/or rotation needs consideration.
