General FAQs

Q: Are stairlifts battery powered?

Yes. Modern stairlifts are battery powered and recharged when sitting at their charging points. Some older models are mains powered and have no batteries. 

Q: What if there's a power cut? 

During a power cut, the stairlift batteries will continue to work on newer models, getting you safely to your destination (read more here). Even if the power cut is taking a while, fully charged batteries are good for at least 15 to 20 rides up and down your stairs, though if you have a powered swivel, you will need to use the manual swivel lever.

Q: How to charge stairlift battery?  

For most brands, stairlift batteries don’t need special checks but make sure your stairlift is never left too long off its charging point. This means “parking” your stairlift after every ride. More recent stairlifts have an alarm or light to let you know, but if you’re uncertain, please ask your service engineer during a service visit to demonstrate.

When not in use, your stairlift should never be left off its charge point. Your stairlift should also be left in the “On” position under normal circumstances. 

Q: How do I know the batteries are okay?

During a service visit, the stairlift engineer will check the current battery chargers and voltage, using battery testers to measure if the batteries are still charging properly. These tests will indicate if a replacement is needed or if the current stairlift batteries are still okay.

Q: Should I turn my stairlift off? 

No! Whatever you do, please don’t turn the main power of your stairlift off. If you keep your stairlift turned off, either regularly or for too long, the batteries will not receive the proper charge; it will degrade the battery, and you'll need new batteries for your stairlift.

Q: What about if I am away for longer than a week?

The batteries are charged every time you use your stairlift and park it; this is important because it guarantees your batteries are always charged. Should you go away for a longer period, for example, more than a fortnight, it’s a good idea to have someone come over to water your plants and take a joy ride on your stairlift.

Q: Why is my stairlift going slow?

If your batteries are running low, there’ll be no buzzing alarm system or flashing lights. Instead, you’ll see one or more of the following: 

  • Your stairlift will go slower than its usual pace or gradually slow in speed as the upward journey progresses
  • Your stairlift will stop after a short distance and then continue
  • The battery won’t charge at its usual charging point (this means the stairlift battery has been completely drained)

At any of these signs, you’ll need to replace the batteries.

Q: How long do stairlift batteries last?

Stairlift batteries 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 degrades the battery and early replacement.

Q: How do you change a stairlift battery?

You should never replace a stairlift battery yourself; it’s tricky if you aren’t a fully trained qualified stairlift engineer. Additionally, accessing the batteries will require covers to be removed and correctly fitted, then the safety features on the stairlift should all be thoroughly checked to ensure they work. An engineer will also identify whether other elements require inspection or could be causing any issue, for example, the charger. 

If you attempt it, you’ll also likely void any warranty or servicing cover should the stairlift fail. You wouldn’t let an untrained gas fitter check your boiler or a non-mechanic fix your car. The principle is the same.

A Stannah service engineer can take care of the replacement for you, ensuring peace of mind and complete safety for the stairlift user(s). And even better, they keep fully approved battery stock in their vans to enable you to get back up and running quickly and ensure safe and correct disposal of a large voltage battery.

Q: How much is a stairlift battery?

Stairlift batteries are covered by the initial installation warranty or a 12-month replacement warranty if replaced. Batteries and fitting are covered on a premium service contract. But expect a charge on lesser contracts. Stannah also safely and correctly dispose of any old batteries - meaning you don't have to worry about it.

Don't be tempted by cheap replacements. All the batteries Stannah keep as van stock are manufacturer-approved, fully fire retardant, and safety marked. Choosing cheaper non-manufacturer approved batteries can damage your stairlift, affect the performance of the stairlift or they may not be fire retardant and risk giving off dangerous fumes in the event of a fire. 

When it comes to Stannah stairlift replacement batteries, it’s best to contact your local Stannah branch. This goes for all your stairlift replacement batteries queries. Who can help you better than a stairlift manufacturer who’s been in the lifting business for more than 150 years?

  • Remember, if you are home alone, we always recommend carrying a mobile phone to alert others if you need help.
  • Keep your local branch or supplier number handy or saved in your phone for emergencies.
  • It's always a good idea to ask someone else to be around to help you troubleshoot.
  • If your stairlift stops on the stairs, it’s best to stay seated and see if you can restart it or summon some assistance. If you do have to get off, make sure you can do so safely, take it slowly and ideally have someone help you.
