- Stored in the base of the chair or carriage
The stairlift:
- Charges when parked at charging points
- Runs on battery power, not directly from mains
This improves safety.
How Batteries Are Checked During Servicing
During a stairlift service, the engineer will:
- Test battery voltage
- Check charging contacts
- Inspect battery condition
- Confirm proper charging behaviour
This helps detect issues early.
