We know all too well about battery heat. Last September after Katrina hit, we made a quick trip to Jackson, Mississippi. While in Jackson (martial law) the coach decided to puke 2 of the chassis batteries. From Memphis down, we had a weird smell in the coach when stopped. ( Icon lite for batteries lit) When we got to the lot to collect our vehicle, I popped opened the bay door where the chassis batteries were.......Whew!!! and were they hot.
Luckily, we found a Interstate Battery dealer open, with phone, power and batteries. Presto, installed new ones, headed out of town before dark, and got to Little Rock by 1 am. with the van on a flatbed behind the coach. Tried to attach a photo, but no luck.
