One key consideration is the battery type used in your wheelchair. Airlines typically only allow certain types of batteries due to safety concerns. Most electric wheelchairs are equipped with either sealed lead-acid batteries or lithium batteries. While sealed lead-acid batteries are generally permitted, lithium batteries have specific restrictions, especially regarding their watt-hour rating. Batteries exceeding a specific watt-hour limit may not be allowed on the plane, and travelers may need to remove the battery and transport it separately in compliance with hazardous material regulations.
