Pack includes two caps, which fit most of the popular wheelchair batteries (eg Invacare).
Most airlines now ask power chair users to isolate the battery on their electric wheelchair before take off. The best and easiest way to do this is to plug in these caps. You need to disconnect the battery by disconnecting the two black leads as shown. The two caps supplied then fit safely and securely onto these ends.
When you have fitted them you can hand your chair over to the airport boarding staff at check-in or just before take-off. If you don’t use these caps the airport staff may wrap the plugs with tape. This is very difficult to get off at the other end and may even damage your chair.
It was a lovely Easyjet steward who opened the powerchair to d/c the battery for me. All airport staff did was try to yank secure wires out!
