Battery life
• The battery life is limited. Battery capacity decreases
little by little as you use it more and more, and as time
passes. When the battery operating time seems to
have been considerably shortened, a probable cause
is that the batteries have reached the end of its life.
• The battery life varies depending on storage,
operating conditions, and environment, and is
different for each battery.
