SAFETY INSTRUCTIONS
• Always keep the charger in good condition.

sufficient lighting.
• Use eye protection (standard spectacles are not adequate) and
protective clothing. Do not touch your eyes while working with
batteries.
• Remove loose clothing, watches, and any jewellery, and contain long
hair. A lead acid battery can cause a short-circuit current sufficient to
weld metal to metal, which will cause dangerous burns.
• Read the vehicle manufacturers instruction manual for specified
battery charging instructions.
• Disconnect the battery and move it to a safe, dry level area for
charging. If the battery cannot be removed, refer to manufacturers
handbook.
• Clean the clamps and battery terminals to remove oxidation.
• When you connect the clamps to the battery, make sure that you
follow the correct polarity. Red is Positive (+) and Black is Negative (-).
• DO NOT pull or lift the charger by its cables.
• DO NOT pull plugs from the sockets by the power cable.
• DO NOT try to charge a non-rechargeable battery.
• DO NOT use the charger for something other than that for which it is
designed.
• DO NOT let the clamps touch each other when the power is on.
• DO NOT get the charger wet or use it in damp or wet locations or areas
where there is condensation.
WARNING: DO NOT USE ON ANY OTHER BATTERIES APART FROM THOSE
MENTIONED IN THE SPECIFICATION TABLE ON PAGE 10 .
WARNING: DISCONNECT THE CHARGER FROM THE MAINS POWER BEFORE
MAKING OR BREAKING DC CONNECTION, SERVICING OR PERFORMING
ANY MAINTENANCE.
WARNING: ENSURE THERE ARE NO SOURCES OF IGNITION NEAR THE
WORK AREA I.E. NAKED FLAMES, SPARKS, CIGARETTES, FLAME HEATERS

THE 3-STAGE CHARGING PROCESS
Stage Description
1 Bulk/Rapid Start Charge (20%-70% charge). The charger delivers
maximum charging amperage to re-energise the battery.
2 Absorption Charge (70%-90% charge) Maintains the charge at a
safe voltage, which remains constant while the current
requirement diminIshes.
3 Maintenance (90%-100% charge) Voltage is automatically
maintained with pulsing low input current. Occasional monitoring
only required.
