Battery packs come as a sealed unit that is maintenance free. Eventually, however, it will lose its ability to hold a charge and need to be replaced. the battery packs attach to the stair lift or are externally mounted near the charge station. It is a good idea to check the cost of batteries when choosing a stair lift, because they will have to be replaced eventually. Stair lift technology has moved away from the use of household AC power to use of rechargeable DC battery packs. While the batteries recharge on the household current, the lift does not require the household current in order to work, allowing use of the lift during power outages and resulting in a much smoother and quieter ride.
The biggest danger with AC powered stair lifts is that during a power failure, the stair lift will not function. Early versions of stair lifts were all AC powered. Trailing electrical cables presented tripping hazards, and the lifts moved in a jerky, start-stop manner due to the nature of the AC powered motor. At that time there wasn’t much choice because battery technology had not advanced as far as it has today. Today, DC powered stair lifts that only recharge from the household supply of electricity are the most popular lift chair designs. With DC powered stair lifts, if the power goes out, the battery can’t charge, but the lift will still be functional until the battery’s charge runs out. These models are quieter than AC models, too.
Stair lifts are chairs that run on tracks attached to stair treads that lift a person up or down the stairs safely. They are an enormous help to someone living alone who has trouble navigating stairs, and for those who live with a spouse, relative or other loved one who is not capable of the hard physical work of carrying the person up and down the stairs. A stair lift usually benefits more people than just the person who uses it. There are a number of reasons why people have trouble going up and down staircases: arthritis, diabetic foot complications, neurological conditions, or a decline in strength due to aging. Giving up the independence of going up and down stairs can be a terrible blow to a person’s morale and self esteem. Suddenly half the house is out of reach, and that person’s world shrinks considerably.
