Bought it because my motorcycle battery was under 10V. 8.5V to be exact. I connected it and every time came the same light on the charger: FAIL. Have the battery removed because I thought she was dead and I brought them to a repair shop in your area. The next day I get it back. Loaded mind. This happened to me two times. This charger only charged batteries. Therefore, I would recommend it only to the want to throw away his money.
