must never be removed from the battery.
oThe safety instructions specified in the user manual must be observed.
oLithium-ion batteries must never be opened, dismantled or mechanically damaged in
any way.
oLithium-ion batteries must not be exposed to heat or fire. During storage, lithium-ion
batteries must be protected from direct sunlight.
oIn case of exceptional heat development during operation, the lithium-ion battery
must be disconnected and removed from the vehicle. Inform your dealer immediately.
oThe lithium-ion battery must never be short-circuited. If several lithium-ion batteries
are stored in a compartment, it must be ensured that the batteries cannot short-circuit
each other. It must also be ensured that the batteries cannot be short-circuited by any
other electroconductive objects.
oThe lithium-ion battery must be kept in the original package until being used.
oLithium-ion batteries must be protected from mechanical impacts.
oIn case of battery leakage, the leaking electrolyte must never come into contact with
skin or eyes. In case of skin contact, the affected area has to be cleaned with water and
soap immediately. In case of eye contamination, the affected eye must be thoroughly
rinsed with clean water immediately. In both cases, a doctor must be consulted
without delay.
oIn case of swallowing of leaking electrolyte, a doctor must be consulted immediately.
oThe lithium-ion battery is usually charged by the electrical system of the vehicle. If the
battery is charged outside of the vehicle, only those chargers can be used that are
recommended by the battery distributor. Alternatively, the battery can be charged by
specially skilled personnel.

following measures are recommended:

Lithium-ion batteries user manual as of December 09, 2020 Page 10 of 19
Inhalation: Leave the contaminated area and consult a doctor without delay!
Eye contamination: Rinse affected eye for 15 minutes with clean water and consult a doctor
without delay!
Skin contact: Clean the affected area with water and soap and consult a doctor without delay!
Swallowing: Consult a doctor without delay!
Correct behaviour in case of fire
Fire extinguishing
In case of a burning lithium-ion battery any type of extinguisher can be used, preferably an
ABC powder extinguisher. This type of extinguisher can be used to extinguish other burning
materials involved in the fire as well. In addition, the fire can also be extinguished with plenty
of water (cooling effect).
Fire fighting instructions
In case of fire, the vehicle ignition must be turned off if possible without risk for the user.
Lithium-ion batteries must be removed from the fire area if possible without risk. Water is
useful to cool down the lithium-ion batteries and the fire area. In case of a burning lithium-
ion battery, the fire department must be alerted in any case, even if the fire could be
successfully extinguished since a renewed flare-up of the fire cannot be excluded. If possible,
the extinguished lithium-ion battery should be observed until the fire department arrives.
Attention must be paid to the fact that new substances are created in the event of a fire and
therefore the fire residues must be inspected by a specialist and disposed of accordingly.
Only carry out fire fighting measures if there is no danger to life and limb. Otherwise leave the
danger zone immediately and inform the fire department.
Effective handling of an accident
Persons must be taken out of the danger zone immediately. In any case the fire department /
police must be alerted. First responders and emergency services must be informed of the
presence of a lithium-ion battery in the vehicle.
If the lithium-ion battery has been flooded or immersed in water, the following measures are
recommended:
In case of flooding, first switch off the power supply to the lithium-ion battery. The flooded
lithium-ion battery must not be reused and must be disposed of in accordance with legal
requirements.
