(c) If the battery on the passenger's wheelchair or other similar mobility device has been labeled by the manufacturer as non-spillable as provided in 49 CFR 173.159(d)(2), or if a battery-powered wheelchair with a spillable battery can be loaded, stored, secured and unloaded in an upright position, you must not require the battery to be removed and separately packaged. Notwithstanding this requirement, you must remove and package separately any battery that is inadequately secured to a wheelchair or, for a spillable battery, is contained in a wheelchair that cannot be loaded, stowed, secured and unloaded in an upright position, in accordance with 49 CFR 175.10(a)(15) and (16). A damaged or leaking battery should not be transported.
