Every year I have to expand and charge the battery in the spring, because I have no electricity in the garage. I once got a powerful Powerbooster 1800 Ah as a starting aid for the car. Question: Can I just clamp it to the mopper battery for a few hours? Would the booster charge the battery then? That would be ideal, because I could then also make a stopover in the winter. Has anyone ever done this before? Ride On Jörg
