- For best results, batteries should be stored
fully charged in a cool dry place. Avoid char-
ging the battery in places subject to high
ambient temperatures (e.g. at a window) as
this has an adverse effect on battery life and
increases the rate of self-discharge.
- If the battery no longer reaches full charge, it
may have lost capacity due to aging or over-
stressing. It is possible to continue working
with a battery in this condition but it should
be replaced in good time.
