This stairlift was given to me by my son and his friend who were doing a house clearance. A kind thought but it wont fit our house. I cannot guarantee the batteries in the stairlift. The track consists of a section from the floor which is a 2.4 metres long straight. There is a straight length ending in a partial curve of 1.7 metres and a 90 degree curve rising to the right. There are short lengths all straight of 30 centimetres, 10 and 23 centimetres. There are 9 adjustable leg supports.
