Responding to fears of lithium battery fires, Southwest Airlines will begin implementing industry best practices this month. As of September 25, 2025, Southwest will require, where possible, passengers with mobility devices to remove the lithium battery from their device and take it into the cabin with them. And from January 2026, Southwest will limit the maximum lithium battery size to 300 watt-hours (Wh). This will apply to mobility devices as well as all other lithium batteries that passengers might be carrying with them.
