I bought it in November 2014. The car and charger are all original. In July 2015, the discharge meter test showed a discharge of 40-50 points, and the normal new battery was 120 points. I was deceived and regretted it to death. The car has a 350W motor and can only run about 50 miles. The previous battery could run 100 miles after half a year. I replaced the reusable battery and it was only February and could only run 30 miles.
