Battery life
• The battery life is limited. Battery
capacity decreases little by little as
you use it more and more, and as
time passes. If the battery operating
time seems shortened considerably,
a probable cause is that the battery
pack has reached the end of its life.
Buy a new battery pack.
• The battery life varies according to
how it is stored and the operating
conditions and environment in
which each battery pack is used.
How to store the battery pack
If the battery pack is not to be used
for a long time, charge it and then
fully use it up once a year on your
camera before storing the battery
pack in a dry, cool place to prolong
the battery life.
