Wheelchairs and mobility aids with non-spillable batteries
If your battery-powered wheelchair or other similar mobility aid uses non-spillable batteries, they must comply with Special Provision A67 or the vibration and pressure differential tests of Packing Instruction 872. The battery terminals must be protected from short circuits, e.g. by being enclosed within a battery container, and the battery must be securely attached to the wheelchair or mobility aid.
You must ensure that your wheelchair or other battery-powered mobility aids are carried in such a manner so as to prevent unintentional operation and that the wheelchair/mobility aid is protected from being damaged by the movement of baggage, mail, stores or cargo. It is recommended that you make advance arrangements with each airline.
Special Provision A67
Non-spillable batteries meeting the requirements of Packing Instruction 872 are not subject to these regulations if, at a temperature of 55°C (131°F), the electrolyte will not flow from a ruptured or cracked case. The battery must not contain any free or unabsorbed liquid.
Any electrical battery or battery powered device, equipment or vehicle having the potential of dangerous evolution of heat must be prepared for transport so as to prevent:
- a short circuit (e.g. in the case of batteries, by the effective insulation of exposed terminals; or in the case of equipment, by disconnection of the battery and protection of exposed terminals)
- unintentional activation.
Note - The battery manufacturer should be able to advise as to whether the battery meets the requirements of Special Provision A67. This is often provided on a material safety data sheet (MSDS) and is usually obtainable from the manufacturer's web site.
