About the "InfoLITHIUM" battery pack
How to store the battery pack
l
Even if the battery pack is not used for a long time, remove the battery pack from the
camcorder, store it in a dry, cool place after fully charging it once per year and then
using the battery pack fully on your camcorder. This is to maintain the battery pack's
functions.
l
To use the battery pack fully on your camcorder, turn on your camcorder and leave it
as it is without a cassette inserted.
Battery life
l
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.
l
The battery life varies according to how it is stored, the operating conditions, and the
environment for each battery pack.
