4.1.8.
The correct charging status of the battery may be determined by using a hydrometer which will measure the specific density of the
electrolyte. The following figures (kg/ltr) apply at 20°C:
WARNING! Be cautious and vigilant as the electrolyte is highly corrosive acid.

CONNECTING CHARGER TO BATTERY
4.2.1.
Ensure that the battery charger is unplugged from the mains power supply before connecting power leads to the battery.
4.2.2.
Select the charger voltage to match that of the battery by setting the rocker switch to either 12 or 24 volts. Initially, always set the
Charge Rate rocker switch to 'mIN'.
4.2.3.
Check the charger clamps and battery terminals to ensure that they are clean and free from oxidation.
4.2.4.
Connect the charger POSITIVE (Red or +) lead to the POSITIVE (+) terminal of the battery and the NEGATIVE (Black or -) lead to the
NEGATIVE (-) terminal of the battery.
CHARGING THE BATTERY
4.3.
4.3.1.
Connect the charger to the mains power supply and turn it on with the front panel mounted ON/Off switch.
4.3.2.
Check the current delivery to the battery by reading the ammeter on the front of the battery charger. During charging the pointer on the
ammeter will slowly move to the left according to the capacity and condition of the battery (see fig.1, meter face may vary according to
model.)
4.3.3.
If a boost charge is required, ensure that an initial charge has built up first before
moving the Charge Rate rocker switch to 'BOOST', see fig.2.
4.3.4.
To indicate that the battery is fully charged the reading on the ammeter should be at
the "0"output indicator. To correspond with this the electrolyte in the battery will begin
to gas. Stop charging at this point in order to protect the battery plates from damage.
WARNING! The charger will not switch off automatically. The state of charge should be
‰
regularly monitored by the person with responsibility for charging the battery.
DO NOT leave the charger operating unattended or overnight.

4.3.5.
Unplug the charger from the mains power supply and then disconnect the clamps from
the battery terminals. Clean and store the charger in a safe, dry area.
4.3.6.
Replace the battery electrolyte cover or caps. Wipe up any splashes or spillages,
remembering that the electrolyte is a corrosive acid. Return the battery to the vehicle,
secure according the manufacturer's instructions and re-connect the power leads.
4.3.7.
Check to ensure that all tools are removed before closing the bonnet or boot.
4.3.8.
SEALED BATTERIES
4.3.8.1.
Charge a sealed battery very slowly, carefully monitoring the voltage across the battery terminals using a normal tester.
4.3.8.2.
When the battery terminal voltage reaches 14.4V for 12V batteries or 28.8V for 24V batteries, stop charging.
4.4.
MULTIPLE BATTERY CHARGING
WARNING! DO NOT simultaneously charge different types of battery or batteries with different capacities or levels of discharge.
‰
4.4.1.
A number of batteries may be charged at the same time. To do so we recommend "parallel connection" as shown in fig.3.
4.4.2.
Two batteries may be charged in series using the 24V output as shown in fig.4.
