§ 175.10 

(A) The packaging must be leak-tight 

and impervious to battery fluid. An 
inner liner may be used to satisfy this 
requirement if there is absorbent mate-
rial placed inside of the liner and the 
liner has a leakproof closure; 

(B) The battery must be protected 

against short circuits, secured upright 
in the packaging, and be packaged with 
enough compatible absorbent material 
to completely absorb liquid contents in 
the event of rupture of the battery; and 

(C) The packaging must be labeled 

with a CORROSIVE label, marked to 
indicate proper orientation, and 
marked with the words ‘‘Battery, wet, 
with wheelchair.’’ 

(17) A wheelchair or other mobility 

aid equipped with a lithium ion bat-
tery, when carried as checked baggage, 
provided— 

(i) The lithium ion battery must be 

of a type that successfully passed each 
test in the UN Manual of Tests and Cri-
teria (IBR; see § 171.7 of this sub-
chapter), as specified in § 173.185 of this 
subchapter, unless approved by the As-
sociate Administrator; 

(ii) The operator must verify that: 
(A) Visual inspection of the wheel-

chair or other mobility aid reveals no 
obvious defects; 

(B) Battery terminals are protected 

from short circuits (e.g., enclosed with-
in a battery housing); 

(C) The battery must be securely at-

tached to the mobility aid; and 

(D) Electrical circuits are isolated; 
(iii) The wheelchair or other mobility 

aid must be loaded and stowed in such 
a manner to prevent its unintentional 
activation and its battery must be pro-
tected from short circuiting; 

(iv) The wheelchair or other mobility 

aid must be protected from damage by 
the movement of baggage, mail, service 
items, or other cargo; 

(v) Where a lithium ion battery-pow-

ered wheelchair or other mobility aid 
is specifically designed to allow its bat-
tery to be removed by the user (e.g., 
collapsible): 

(A) The battery must be removed 

from the wheelchair or other mobility 
aid according to instructions provided 
by the wheelchair or other mobility aid 
owner or its manufacturer; 

(B) The battery must be carried in 

carry-on baggage only; 

(C) Battery terminals must be pro-

tected from short circuits (by place-
ment in original retail packaging or 
otherwise insulating the terminal e.g. 
by taping over exposed terminals or 
placing each battery in a separate plas-
tic bag or protective pouch); 

(D) The battery must not exceed 300 

Watt-hour (Wh); and 

(E) A maximum of one spare battery 

not exceeding 300 Wh or two spares not 
exceeding 160 Wh each may be carried; 

(vi) The pilot-in-command is advised 

either orally or in writing, prior to de-
parture, as to the location of the lith-
ium ion battery or batteries aboard the 
aircraft. 

(18) Except as provided in § 173.21 of 

this subchapter, portable electronic de-
vices (e.g., watches, calculating ma-
chines, cameras, cellular phones, 
laptop and notebook computers, 
camcorders, medical devices etc.) con-
taining dry cells or dry batteries (in-
cluding lithium cells or batteries) and 
spare dry cells or batteries for these 
devices, when carried by passengers or 
crew members for personal use. Port-
able electronic devices powered by lith-
ium batteries may be carried in either 
checked or carry-on baggage. Spare 
lithium batteries must be carried in 
carry-on baggage only. Each installed 
or spare lithium battery must be of a 
type proven to meet the requirements 
of each test in the UN Manual of Tests 
and Criteria, Part III, Sub-section 38.3 
and each spare lithium battery must be 
individually protected so as to prevent 
short circuits (e.g., by placement in 
original retail packaging, by otherwise 
insulating terminals by taping over ex-
posed terminals, or placing each bat-
tery in a separate plastic bag or protec-
tive pouch). In addition, each installed 
or spare lithium battery must not ex-
ceed the following: 

(i) For a lithium metal battery, a 

lithium content of not more than 2 
grams per battery; or 

(ii) For a lithium ion battery, the 

Watt-hour rating must not exceed 100 
Wh. With the approval of the operator, 
portable electronic devices may con-
tain lithium ion batteries exceeding 100 
Wh, but not exceeding 160 Wh and no 
more than two individually protected 
lithium ion batteries each exceeding 
100 Wh, but not exceeding 160 Wh, may
