Federal regulations allow a lithium ion, spillable (wet cell) or non-spillable (dry cell) battery to remain installed only if it is securely attached to the mobility device, the battery housing provides protection from damage, and the terminals are protected from short circuit. We will perform a visual inspection of the battery and the wheelchair or mobility aid; it will not be transported if the battery shows sign of previous leakage or damage.
A lithium-ion battery that’s been removed from a mobility device must be transported in the cabin with the terminals properly protected, but may not contain more than 300 watt hours or 25 grams of lithium. Customers may carry on up to two (2) spare lithium-ion mobility aid batteries as long as the combined total is less than 300 watt hours or 25 grams.
Spillable batteries may need to be removed from the device and transported in a special battery box if the mobility device cannot be loaded, secured, and unloaded in an upright position. Frontier will provide the battery box if necessary.; Frontier may accept a battery box provided by a customer if it meets DOT requirements.
Wheelchairs or mobility devices with non-spillable batteries that do not have an effective way to prevent unintentional activation will be transported with the battery disconnected and the terminals protected to prevent short circuits. If the wheelchair is equipped with an electronic memory chip, disconnection may cause memory loss.
