if it stopped working wile you were useing last year, did it just stop or did it die down? if it just stopped, then its not the battery, is the charger showing any light when pluged in? is the fuse in the charger plug ok? is there a safty brake on the handel , that is set to stop?you realy need a meter to read the battery for power. to see if its getting the charge,or if you could get a car bulb,or any 12volt bulb. and take out the battery , get two wires put one of them to the power point on the battery and the other to the other powerpoint , and the other end to the side of the bulb and the other to the brass tip on the bulb, and see if it will light, if so the battery is ok and takeing the charge, but if you had a multimeter it will tell you just how the battery is, or if any spark out there you know, might test the battery for you, or some good hardware store or hire all store might test it for you if you ask them ,
