I have a Harbor Freight $5.99 maintainer,works good. I hang the charger cords over a mirror, or run it through the steering wheel as a reminder to unplug. For trailers, welder, mowers and atv, I prefer the solar chargers, $20 to $30 and no cords or electric use. Power Up makes a thin lined one, model bsp-5x5-12, and adhere it with silicon.
