Another good tip on batteries is to build it into a box and off the van floor batteries don`t like cold base. I always put a polystyrene/ sajex base at the bottom so it keeps the bse warmer. My dad always said never charge a battery on the floor.
My batteries last 3 years.
 Apparently if a battery gets run down and also cold before recharging it will not last long.
