Query: Split battery and leaking

I've had my Xantrex 1500 now for about two years, came home today and the house smelled of something electrically hot. After searching I found that the Xantrex 1500 was the source of the odor, and I noticed the case felt very warm. I rolled it outside and removed the top cover. There are three AGM batteries inside and one of them was extremely hot to the touch and had split open with electrolyte leaking out. The other two batteries looked OK. The odor was the hot battery.Glad it didn't start a fire.
