To avoid damaging the car's electrical
system and electronics, the following rules
must be followed when charging the battery
or jump starting the car.
• If the charger or starter unit can be set to
different voltages (6V/12V/18V/24V), 12V
must be selected.
• Follow the manufacturer's instructions
supplied with the charger or starter unit.
• No other apparatus that are grounded or
connected to the mains must be con-
nected to the car during charging or jump
starting.
• The charger or starter unit must under no
conditions produce a voltage greater
than:
• 16V continuous
• 18V for 60 minutes.
• If you are unsure about the charge rating
of the unit, disconnect the battery clamp
from the positive terminal before
connecting the unit to the battery.
