13. Information about the battery
Additional safety instructions
We pay a great deal of attention to the design of every battery pack to ensure that
we supply you with batteries which feature maximum power density, durability
and safety.
The battery cells have a wide range of safety devices. Each individual cell is
initially formatted and its electrical characteristic curves are recorded. These
data are then used exclusively to be able to assemble the best possible battery
packs. Despite all the safety precautions, caution must always be exercised when
handling batteries. The following points must be obeyed at all times to ensure
safe use. Safe use can only be guaranteed if undamaged cells are used. Incorrect
handling can cause cell damage.
Important: Analyses confirm that incorrect use and poor care are the main causes
of the damage caused by high performance batteries.
Information about the battery
1. The battery pack supplied with your cordless tool is not fully charged. The
battery pack has to be charged before you use the tool for the first time.
2. For optimum battery performance avoid low discharge cycles. Charge the
battery pack frequently.
3. Store the battery pack in a cool place, ideally at 15°C and charged to at
least 40 %.
4. Lithium-ion batteries are subject to a natural ageing process. The battery
pack must be replaced at the latest when its capacity falls to just 80 % of its
capacity when new. Weakened cells in an aged battery pack are no longer
capable of meeting the high power requirements and therefore pose a
safety risk.
5. Do not throw battery packs into an open fire. There is a risk of explosion!

INFORMATION ABOUT THE BATTERY
6. Do not ignite the battery pack or expose it to fire.
7. Do not exhaustively discharge batteries. Exhaustive discharge will damage
the battery cells. The most common cause of exhaustive discharge is lengthy
storage or non-use of partly discharged batteries. Stop working as soon as
the performance of the battery falls noticeably or the electronic protection
systemt riggers. Place the battery pack in storage only after it has been fully
charged.
8. Protect batteries and the tool from overloads. Overloads will quickly result
in overheating and cell damage inside the battery housing without this over-
heating actually being apparent externally.
9. Avoid damage and shocks. Replace batteries which have been dropped from
a height of more than one meter or which have been exposed to violent
shocks without delay, even if the housing of the battery pack appears to be
undamaged. The battery cells inside the battery may have suffered serious
damage. In this respect, please also read the waste disposal information.
10. If the battery pack suff ers overloading and overheating, the integrated pro-
tective cut-off will switch off the equipment for safety reasons. Important. Do
not press the ON/OFF switch any more if the protective cut-off has actuated.
This may damage the battery pack.
11. Use only original battery packs. The use of other batteries may result in
injuries, explosion and a fire risk.
12. Protect your rechargeable battery against moisture, rain and high humidity.
Moisture, rain and high humidity can cause dangerous cell damage. Never
charge or work with batteries which have been exposed to moisture, rain or
high humidity – replace them immediately.
13. If your equipment is fitted with a detachable battery, remove the battery for
safety reasons after you have finished your work.
