The scooters at Walmart run fatards up and down the snack food aisles all day long on a single charge.
A couple trips on a staircase doesn't seem much different.



It all depends on the size of the battery. The stair lift is made to
sell and make a profit for the company. The smaller the battery,the
more profit.

Where I worked there were battery powered pallet trucks. They would
haul a man and a load of 800 pounds for about 8 hours. The battery did
weigh in at about 500 pounds and was a lead acid type. I am sure there
is better batteries now as those were being made in the 1970's.
