I tell everyone that owns a scissor or an electric boom, the batteries are the single most important part of the machine. If you don¡¯t take care of them, you will run into many problems in the future. The contactor fails, then the motor to start. Scissor lifts are 24v DC with 4 6v deep cycle batteries. Check the date on them and always be wary of mismatched sets.?
