Battery Information
The system is designed to operate most efficiently with sealed
lead acid (SLA) batteries. Sealed lead acid batteries cost
slightly more, but they can last longer. The oversize battery
case (included) will accommodate a 12-volt SLA battery (up to
a 27-frame size).
Be certain that the area around the batteries is well ventilated.
Before servicing the batteries, blow away gasses by waving a
piece of cardboard near the batteries.
Dangerous hydrogen gas CAN
