vehicle batteries to a special collection
point.

handling the battery.
All operations on the battery must be
carried out in a well ventilated area and
away from naked flames and sources of
sparks, so as to avoid the risk of explosion
or fire.
Wash your hands afterwards. If your vehicle has an automatic gearbox,

a battery charger.
Never use a 24 V or higher battery
b o o s t e r.
First check that the slave battery has a
nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact
with each other.
Switch off all the electrical consumers
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are not
