Why are some Mobility Scooters with lithium batteries not allowed on airlines ?

Some Mobility Scooters are not allowed on airlines due to the fire risk posed by large lithium-ion batteries, which can overheat and ignite. Regulations set by the FAA and individual airlines restrict the watt-hour (Wh) rating of batteries and often ban devices with very large batteries entirely, regardless of their size, to ensure passenger and crew safety. Airlines also prohibit certain types of batteries, like damaged or recalled ones.

Battery size restrictions:

Large batteries: Batteries rated over 160 Wh are often banned from both carry-on and checked baggage.
Watt-hour (Wh) limits: Batteries must often be below 300 Wh for certain types of travel, but this can vary by airline. The calculation is: volts x amp hours = watt hours.
Smaller batteries: Batteries between 100–160 Wh may be permitted but often require prior approval from the airline.

Fire safety concerns

Risk of fire: Lithium-ion batteries can pose a fire risk.
Cabin vs. cargo: Fires are more easily contained in the cabin than in the cargo hold, which is why some airlines want large batteries to be with the passenger, not in the cargo hold.
Damaged batteries: Any damaged, defective, or recalled lithium batteries or devices containing them are prohibited from both carry-on and checked baggage.

Airline policies

Strict rules: Some airlines have blanket bans on certain personal battery-powered devices, such as electric scooters, due to safety concerns.
Varying rules: Not all airlines have the same rules, so it's essential to check with your specific airline well in advance of your flight to understand their battery policies for mobility devices.
Pre-approval: You may need to contact the airline at least 48 hours in advance to get approval for your mobility scooter.

The best practice seems is check with your airline in advance prior to your travel to be sure their rules have not changed, and to avoide unpleasant surprises.

Have a safe flight!
