Since we don't have access to an outlet while it's stored in the parking lot, it is the next best thing to do. If we did I would have put it on a battery maintainer instead. The cover we purchased is supposed to have straps attached. We haven't opened it yet, so we'll have to see how securely it fits. We're going to park it along the gate, so hopefully it will get a little shelter from the wind. I guess will see when we return
