This is a motorcycle battery charger from BAL (Ohashi Sangyo). Suitable for mopeds, scooters, motorcycles, and light automobiles. I purchased it in 2011, but I've only used it about once every two years, so it's only been used about 10 times, and there are no noticeable scratches. I used it to charge motorcycle batteries. It works without any problems, and batteries that were dead would be revived overnight. I'm selling it because I've gotten rid of my motorcycle.
