These batteries are perfect for your bus. They are AGM type lead-acid batteries with a design life of ten years in backup service. They will not freeze as long as there is a charge in them, and they produce no fumes (except during a SERIOUS overcharge). They do, however, like a temp of about 70 degrees. They are maintenance and spill free and can be kept inside the bus. These particular batteries are group size 31, and are approximately 125 AH. I put a three year old pair in my deuce and a half (BIG army truck). That was 4 1/2 years ago and they still will start the truck even after sitting idle for months.
