If you have a stairlift with a DC battery, then these will generally last around 2 to 5 years; of course, this depends on the usage. For example, if the stairlift is often left off its charge point, it reduces battery life.
The batteries included with our DC stair lifts are rated for 3,200 cycles. A "cycle" is a one-way trip up or down the stairs, so a round trip up and down the stairs is considered two separate cycles.
If you make one round trip up and down the stairs every day (two cycles per day). At this rate, the batteries will last over four years averaging 730 cycles a year
If you make two round trips with your stair lift each day, he batteries will last a little more than two years, your stair lift is doing 1,460 cycles per year.
If you make three round trips per day, expect the batteries to last about a year and a half.
If you make four or more round trips per day, expect the batteries to last one year or less.
There are other considerations to make as well, if you don't use the stairlift every day, you still shouldn't expect the batteries to last much longer than four years, as these will need replacing after this to ensure maximum power is controlled, If the stair lift is used in an environment that is not temperature-controlled or if the person who uses it is near the maximum weight capacity, the battery will not last quite as long, with all stairlifts Carelift supply we offer a service once a year where the battery will be checked and tested thoroughly and our engineers can let you know roughly how long the battery life has left.
If you think you'll be using your new stairlift for three round trips or more every day, you may want to consider an AC-powered stair lift. Although you would not be able to use it in the event of a power outage, you would not have to bother replacing the battery every year.
