3 OPERATION
 WARNING! This charger is suitable only for lead Acid Batteries and should
not be used to re-charge Ni-Cd or any other type of battery.

DO NOT charge batteries smaller than 20Ah or greater than 120Ah.
 WARNING! Ensure you read, understand and apply the safety and
operational instructions before connecting the charger power clamps to the
battery. Only when you are sure that you understand the procedures is it safe
to proceed with the actual charging process.
3.1 BATTERY PREPARATION
Caution ! Ensure you wear appropriate personal protection including safety
goggles as some electrolyte spillage may occur during the following
procedure
It is advised before charging, to disconnect and remove the battery from the vehicle
to prevent damage to sensitive on-board equipment.
Caution ! Before removing or replacing your battery ensure you read the
vehicle handbook and carefully follow the instructions relating to battery
removal and fitting.
3.1.1 If the battery is not a sealed unit, remove the filler caps and check the
level of the electrolyte. If it is below the recommended level, top up using
distilled water. Do not use tap water under any circumstances.
3.1.2 To prevent acid splashing during the charging process, replace the filler
caps but do not tighten them, allowing gases to escape.
3.1.3 If sealed unit, it is unnecessary to carry out these checks.
3.2 CONNECTION
3.2.1 To avoid sparks which could cause an explosion, ensure the charger is
disconnected from the mains supply before making or breaking
connections.
3.2.2 Connect the crocodile clips to the battery in the following order:
a) Connect positive charging lead (RED) to the positive post of the battery
(marked P or +).
b) Connect the negative lead (BLACK) to the negative post of the battery
(market N or -). It is important that the crocodile clips make good
contact with the battery terminals. If necessary use a small wire brush
to clean the terminals.
3.3 CROSS POLARITY AND SHORT CIRCUIT PROTECTION
3.3.1 The battery charger has an internal protective device, if the charger is
connected so that polarities are crossed or there is a short circuit, it will
shut off the charger. The charging LED's will light up then will turn off.
If this happens turn off the charger at the mains, remove the mains
plug and disconnect from battery removing the negative clip first. Leave
for a couple of minutes to allow the charger to cool down then re-connect
crocodile clips to battery as in 3.2.2. Insert the plug back into the mains
supply and continue charging the battery. The charger should be fully
operational.
3.4 CHARGING
3.4.1 Plug the charger into the mains supply (230V AC only).
3.4.2 Switch on supply to commence the charging procedure.
3.4.3 The rate of charge will now be displayed by the LEDs on the front of the
charger.
The larger the number of LEDs illuminated, the lower the charge state of
the battery and higher the current flowing into the battery. As the battery
charges, less current will be drawn and less LEDs will be lit. When the
battery is fully charged, no LEDs will be illuminated. When a flat battery is
initially connected to the charger, the charging rate should build up
quickly. As the battery becomes more charged the rate of charge will
drop, this is normal.
 WARNING! Do not attempt to start the vehicle whilst connected to the
charger as this will damage the unit.
3.4.4
Regularly check the specific gravity of the electrolyte using a hydrometer,
until a reading of fully charged is reached.
A charging time of no more than 10hrs is advised for batteries of 34 to 45
Ah capacity.
3.4.5 When charging is complete, switch off the mains supply. Unplug the
charger and disconnect the leads from the battery removing the negative
clip first. Inspect the electrolyte levels in each of the battery cells and top
up if necessary using distilled water. Replace the filler caps ensuring they
are fully tightened or pushed home. Any surplus fluid on the . . surface of
the battery should be wiped off (this should be done with extreme care as
it may be acidic).
4 FAULTS
 WARNING! DO NOT use the charger if damaged or
thought to be faulty (Contact Service Agent).
