Can a reglar 12v car battery be used in a power weelchare?
Yes,you can use a car battery. The reason for specialized wheelchair batteries is; [1]Car batteries are made for starting while deep cycle batteries have a more even current flow over a longer period of use and will also withstand being drained whereas car batteries are damaged by being drained dead.And [2]: Wheelchair batteries are filled with a gel type acid unlike car batteries that are filled with liquid acid.This means that if the chair is not fairly level there is going to be some acid leaking out and doing damage unless promptly washed with water. Go ahead and use the car batteries but be careful and don’t expect the same performance.Marine deep cycle batteries would be better.
