The London Fire Brigade warns that lithium batteries in mobility scooters and electric wheelchairs can be a fire risk if overcharged, tampered with, exposed to extreme temperatures, submerged or damaged. Its advice: never cover a charging battery, unplug it when full or before you sleep, and stop using it if it overheats, bulges, smokes or fizzes.
The Office for Product Safety and Standards adds: use the right charger, charge while you're awake and at home, and never charge or store a battery where a fire would block your escape route.
A note on data: we couldn't find a reliable national count of mobility scooter thefts. ONS and police figures don't separate them out, so we don't quote one. Compare theft cover →
