Stairlift Battery Replacement

Stairlifts run on rechargeable batteries, and like any battery these eventually wear out. Knowing the signs, and how to look after them, keeps your lift running reliably.

Quick answer: Stairlift batteries typically last a few years. Signs they need replacing include beeping, running slowly, stopping before the top, or not holding charge even when parked correctly. Replacement is a quick job best done by a qualified engineer. Leaving the lift on its charging points prolongs battery life.

How stairlift batteries work

A stairlift runs on rechargeable batteries that top up whenever the lift is parked on its charging points. This is why it's important to leave the lift at a charge point rather than stopped mid-stairs, otherwise the batteries slowly drain.

Signs the battery needs replacing

• The lift beeps to warn of low power.
• It runs more slowly than it used to.
• It stops before reaching the top.
• It won't hold charge, even when parked correctly on the charging points.

How long batteries last

Stairlift batteries generally last a few years before they need replacing. Regular use and keeping the lift on charge both help them reach a full lifespan.

Keeping your battery healthy

• Always park the lift on its charging points when not in use.
• Keep the charger switched on at the wall.
• Have the lift serviced annually so the battery and charging system are checked, see our servicing guide.

Getting the battery replaced

Battery replacement is straightforward but best carried out by a qualified engineer, who will fit the correct battery and check the charging system at the same time.

If your stairlift is old and the battery is one of several parts wearing out, it may be more cost-effective to replace the lift. You can get a free, no-obligation quote for a new stairlift below.
