Safety precautions while vehicle storage battery charging
Remember that any battery charging process implies supply of voltage exceeding the
rated 12 V to the storage battery and accordingly to vehicle circuits, which may damage
factory electronic and optional electronic equipment f vehicle.
Do not use charging and starting-charging devices for storage battery charging directly on
vehicle without disconnecting battery terminals from vehicle circuits in following modes:
• rapid charging by increased current («boost» or similar modes);
• various START modes intended for engine starting
Never use starting and charging devices for engine starting with main battery disconnected
or with inoperable main batteries connected (short circuits in banks, breakage of plates
etc.)
Never use faulty charging devices, 24V charging devices and other power supply
equipment (i.e. welding inverters), not dedicated to charge 12V vehicle batteries.
It is recommended do not use so named “light up” method for charging vehicle battery and
start engine by connecting cables from a donor vehicle battery.
Owner is fully responsible for possible short circuit or surge voltage and damaging of
security system and vehicle electronic components caused while using this method.
Follow a safe storage battery charging procedure !
Before charging a battery terminals shall be disconnected from vehicle circuits.
Then that battery charging process can be started. After charging, connect battery
terminals back to vehicle circuits.
It is necessary due to impossibility of detecting main battery charge and health state
without specific measuring equipment (i.e. internal short circuits or plates breaks).
Connecting a charging device to an inoperable storage battery may cause a risk of
car electronic equipment and security system damage with increased over limit voltage.
