Possibly one designed not to leak at low outside pressure (many cells are presurised by charging) ....

Quote: Most modern power-operated wheelchairs have some form of safety battery so that they can be carried without risk of damage to the aircraft

Usually gel acid unspillable but emit hydrogen gas when charging
however a catilist will convert gas to water
