At
temperatures around 20°C
(68°F), AA-type alkaline-manga-
nese batteries give the highest
overall performance, including
faster advance rates and a greater
number of rolls of film.
At
lower
temperatures, however, the perfor-
mance of alkaline-manganese
batteries deteriorates. For shooting
at low temperatures,
it
is advised
that you use NiCd batteries. (See
table on page 108).
