under reasonable foreseeable environmental
conditions with respect to magnetic fields,
EM-fields, electrostatic discharges, pressure or
variations in pressure, acceleration etc.
• If this product is used with or mounted in a
vehicle it may only be used when the vehicle is
not in use.
• When in use, position this product so that the
label can be read – within 40 cm of the

• Lead-Acid chargers are designed for charging
Lead-Acid batteries only.
• Make sure you have the correct battery charger
for the Lead-Acid battery you wish to charge.
For safety reasons, individual battery types
should have a minimum capacity - please refer
to the specifications at the end of this manual.
• Do not attempt to charge batteries that are not
rechargeable.
• Please check that the specifications for your
battery allows for the maximum charge current
indicated on the charger.
• Please check that the specifications for your
battery allows for the environmental conditions
present during charging.
• If in doubt; contact the battery manufacturer for
the specific battery.
• Before charging flooded lead-acid batteries,
check the electrolyte level. If necessary top up
with distilled water up to 5-10 mm over the
lead-plates.
• Old, sulfated Lead-Acid batteries usually have
a reduced capacity and are difficult to charge.
The charge current will fall rapidly as if the
battery had received a full charge. Even though
a battery in this condition should be replaced, it
will retain a small charge.
• As explosive gases may arise during charging
lead-acid batteries the charger and the battery
should be placed in a well-ventilated area during
charging. Avoid sparks and open flames.
• Make sure the charger is disconnected from the
mains. Connect the charger to the battery before
connecting it to the mains (to avoid possible
sparks).
• Please ensure correct polarity when connecting
to the battery terminals. Reverse polarity con-
nection may, in some chargers, result in a fuse
blowing, leaving the charger useless.
• When charging batteries other than vehicle
batteries, it is recommended that you connect
the charger to the mains before connection is
made to the battery. This will reduce the sparks
that may occur due to difference in potential
