This tool helps you quickly calculate the watt-hour (Wh) rating of lithium-ion batteries used in mobility aids, such as electric wheelchairs and scooters. Airlines will require you to contact them at least 48 hours before travel, or at the time of booking, to seek approval for carriage of such batteries. This tool helps determine the battery’s watt-hour capacity and the likelihood of acceptance based on airline safety guidelines.

Simply enter the battery’s nominal voltage (V) and capacity (in ampere-hours (Ah) or milliampere-hours (mAh)) to instantly calculate the watt-hour rating and find out if your battery meets airline requirements for safe travel.
