Additional Information
Battery life
•The battery life is limited. Battery capacity drops little by little as you use it more and
more, and as time passes. When the available battery time is shortened considerably, a
probable cause is that the battery pack has reached the end of its life. Please buy a new
battery pack.
•The battery life varies according to how it is stored and operating conditions and
environment for each battery pack.
