PREPARATION FOR CHARGING
Before charging check that the capacity of the battery (Ah) is not less than 20 Ah, that the
battery is suitable type for charging with this charger and the voltage of the battery is suit-
able for charging with this charger.
Remove the caps of the battery charger (if fitted) to let the gas produced escape.
Check that the level of the electrolyte covers the plates of the battery. If not add distilled
water to cover them
WARNING! PLEASE WEAR EYE PROTECTION AND USE THE EXTREME CAUTION DURING
THIS OPERATION AS THE ELECTROLYTE IS A HIGHLY CORROSIVE ACID.
Please remember that the correct charging status of the battery can be determined by using
a hydrometer which permits to measure the specific gravity of the electrolyte.
The following density values (kgs/1 at 20 C) as a reference point:
1.28 = Fully charged battery
1.21 = Half Charged battery
1.14 = Flat battery
Check that the charger is turned off and is disconnected for mains supply. Connect the posi-
tive charging lead to the appropriate output terminal on the charger for the type of battery
to be charged ie 12 or 24 volt.
CHARGING
Connect the red clamp to the positive terminal (+) of the battery and the black clamp to the
negative terminal (-).
Select the mode switch to the charge position
Select a suitable charge setting.
Connect the mains cable to the mains and set the switch in “ON” position.
The ammeter of the battery charger will indicate the current delivered to-
wards the battery (beginning of charge).
Note: THE CORRECT CHARGE RATE CAN BE DETERMINED BY DIVIDING THE AH CAPACITY
OF THE BATTERY BY 10. EXCEEDING THIS CAN REDUCE THE LIFE BATTERY.
During the charge the pointer of the ammeter will decrease slowly according to the capacity
and condition of the battery.
Note: BOOST FUNCTION CAN BE USED FOR A SHORT PERIOD TO BOOST A BATTERY TO
ASSIST IN STARTING.
Periodically check the specific gravity to determine the state of charge.
