Run time depends on where the parental control "governor" is set: 2-6 hours. Recharge 3-4 hours in a pinch, but overnight recommended.
Stock batteries are $50ish x 2, but they have poor clip-type connections that are a weakness. So when my stock batteries wore out, I replaced them with standard 12v deep cycle batteries a buddy had lying around.
