A cordless polisher keeps a cord from dragging across fresh paint and works in a driveway, a parking lot or a boat slip with no outlet. Most are sold as bare tools for a maker’s battery platform, so the cheapest choice is usually the one that fits the batteries you already own. Check the price with batteries and a charger before comparing a bare tool with a kit. Runtime varies by battery size; RUPES rates its HLR15 at 30 to 40 minutes per battery, so a second battery helps on a whole car.
