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 first stringer can be laid on the floor using blocks and one end of each riser is attached to each bracket so that the risers are in a vertical position in relation to the stringer. The risers are attached to each bracket using blind screws through the holes in the brackets. The second stringer is then positioned over the opposite ends of the risers and attached. A clamp may be used to pull the stringers tight against the riser ends. This one step will eliminate up to 80% of the custom fitting normally required for conventional stairs.
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.
