6.3 Transport and storage
WARNING
Fire hazard. Risk of short circuiting.
▶ Never store or transport Liion batteries in loose, bulk form.
▶ Remove the battery before transporting or storing the drill / driver.
▶ Observe the nationally and internationally applicable transport regulations when shipping batteries by
road, rail, sea or air.
Note
Ideally, the battery should be stored in a fully-charged state in a dry place that is as cool as
possible. Storing the battery in places subject to high ambient temperatures (e.g. at a window) has
an adverse effect on battery lifetime and increases the rate of self-discharge.
If the battery no longer reaches full charge, it may have lost capacity due to aging or overstressing.
It is still possible to work with this battery. You should, however, soon replace the battery with a
new one.
