Operating Environment and Placement
1. The charger shall be used in a well-ventilated and dry place free from direct sunlight or corrosive gas and
away from sources of heat.
2. Operate the charger as far away as possible from battery and ensure the charger and battery are placed on a
strong and stable surface.
3. Never place the charger directly on the battery or battery on the charger.
4. During charging, if the temperature of battery exceeds 104°F (40°C), current shall be reduced. If temperature
exceeds 113°F (45°C), charging shall be stopped. Charging should not be recommenced until the battery
temperature reduces to below 104°F (40°C).
Charging Operation
1. Check and top up battery electrolyte as required using distilled/demineralised water.
2. Ensure battery caps are in place and secure and that the cap vents are not obstructed or there is a risk of
deforming or bursting the battery casing.
3. Turn the “select voltage” switch and “select current” switch of the charger to the positions corresponding to
the voltage and capacity of the battery. Turn the “charge/start” switch to “charging” position and ensure the
power switch remains in the “OFF” position.
4. Clamp the red clip of charger to the + polarity of the battery and black clip to the - polarity of the battery
and confirm that connection is correct.
5. Connect the battery charger to the power supply.
6. Turn the power switch to “charging” position for charging. Observe whether the indication of current meter
is normal or not. Note:
a) This charger will only operate with a storage battery with a residual voltage of >4V. If the
residual voltage of battery is <4V, there is no current output.
b) The ammeter of this charger is not a precision instrument and only gives a rough indication of
charging current. Likewise the “state of charge” indicator is not a precision instrument. Measuring
the specific gravity of the electrolyte using a hydrometer will provide a more accurate determination
of charge state.
7. When “FULL” indicating lamp lights up, check the density of the electrolyte. If the density reaches 1.28,
charging is complete. If the battery charging is complete, switch the power switch of the charger to “OFF”
position and disconnect from the power supply. Remove the two clips on the + and – polarities of battery
(remove the negative clip first).
