Product Familiarisation
Unpacking your battery charger
• Carefully unpack your battery charger. Ensure all packaging materials are
removed and fully familiarise yourself with all features of the product.
• If any parts are damaged or missing, have these parts repaired or replaced
before use.
Operating Instructions
WARNING: Do not connect the charger to the mains power supply until instructed
in the steps below.
Connecting to battery (In Vehicle)
• This charger is suitable for use on 12V/24V, negative earth, electrical systems.
• Marine batteries must ALWAYS be moved to dry land for charging. This charger
is not designed for use in a marine environment.
• If appropriate, check battery fluid level before charging. Top up with distilled
water if required. Check battery manufacturer’s guidance as to whether cell
caps should be removed for charging.
• Ensure that engine is stopped, and that all electrical accessories (lights, radio
etc) are switched off. Keep vehicle bonnet, boot or access panels, open during
battery charging.
• Locate battery and identify battery terminals. The positive terminal is usually
marked with a “+” symbol, the negative terminal is usually marked with a
“-“ symbol. If you are unsure of which terminal is which, seek professional
assistance.
• Refer to vehicle manufacturer’s handbook to determine whether terminals
should be disconnected for charging. Follow manufacturer’s guidance.
• If the battery terminals are corroded, or dirty, clean them with a suitable wire
brush.
• Attach positive clamp (3) to positive battery terminal.
• Attach negative clamp (4) to a clean part of the vehicle chassis, or other sturdy
metal part. Do not connect the clamp to any part of the vehicle’s fuel system.
• Check that clamps are securely connected, and that they will not come loose
during charging process.
Connecting to battery (Free Standing)
• This charger is suitable for use on 12V/24V lead acid batteries.
• If appropriate, check battery fluid level before charging. Top up with distilled
water if required. Check battery manufacturer’s guidance as to whether cell
caps should be removed for charging.
• Identify battery terminals. The positive terminal is usually marked with a “+”
symbol, the negative terminal is usually marked with a “-“ symbol. If you are
unsure of which terminal is which, seek professional assistance.
• If the battery terminals are corroded, or dirty, clean them with a suitable wire
brush.
• Attach an insulated battery cable, at least 600mm long, to the negative battery
terminal.
• Attach positive clamp (3) to positive battery terminal.
• Attach negative clamp (4) to negative battery cable.
• Check that clamps are securely connected, and that they will not come loose
during charging process.
Charging battery
• Check that the voltage selection switch (1) is positioned correctly for the voltage
of the battery being charged.
• Connect the charger to the mains power supply.
• Set the charge rate selection switch (2) to the appropriate position for the
battery being charged. NOTE: Batteries should only be charged at a current
equal to 1/10 of their Ah rating (e.g. a 100Ah battery should not be charged at a
current greater than 10A), if the battery has been allowed to deep discharge do
not charge at a rate greater than 1/20 of their Ah rating.
• The charge rate can be monitored by referring to the ammeter (5). If the charge
rate is too high, move the charge rate selection switch (2) to the “MIN” position.
• For a quick charge to refresh a partially drained battery, allow 5-10mins
charging time in the “BOOST” position
• As the battery charges, the charge rate will gradually decrease. When the
reading on the ammeter (5) reaches “0”, the battery is fully charged.
NOTE:
• When charging very cold batteries, the initial charge rate may increase as the
battery warms. Do not attempt to charge a frozen battery.
• Internally damaged (shorted) batteries will draw very high current, without
charging. If the battery has been charging for 5-10mins and shows no reduction
in charging current, the battery may be damaged. Stop charging and have
battery professionally tested.
• Disconnect the charger from the mains power supply. Leaving the battery
connected may result in overcharging and permanent battery damage.
• Disconnect the negative clamp (4).
• Disconnect the positive clamp (3).
• Reattach battery terminals if required.
Maintenance
Cleaning
• Keep your battery charger clean. Always clean dust or particles away, and
never allow ventilation holes to become blocked. Use a soft brush, or dry cloth
to clean the machine. If available blow through the ventilation holes with clean,
dry, compressed air.
• Make sure that the positive, and negative, lead clamps are kept especially clean.
Dirty electrical contacts will severely impair the performance of this product.
