4. OPERATION
WARNING! The charger does have an on/off switch. The on and off commands are controlled by the on/off switch on the back of the
‰
unit which is only operational once the ac plug of the spbc30 & spbc40 has been plugged into the ac electrical wall socket.
4.1.
BATTERY CHARGER PROTECTION SYSTEMS
4.1.1.
Over-charging protection
The battery charger contains an advanced microchip monitoring and controlling system to ensure that the battery does not become
overcharged which can result in the loss of electrolyte or in internal short circuit which can cause damage to the battery.
4.1.2.
Overload protection
Overload protection will activate when the current exceeds 120% of the maximum working current.
4.1.3.
High temperature protection
High temperature protection will activate when the internal temperature of the charger rises above 50°C. If this occurs, the charger
output is automatically reduced. Once the temperature is below approximately 35°C, the charger output will return to normal. This
feature is designed to protect the battery and the battery charger when they are being used in environments with very high ambient
temperatures.
4.1.4.
Even charging function
By slowly raising the voltage, the batteries cells with a lower voltage are not charged too quickly which can overheat individual battery
cells, compared to battery cells with a higher voltage.
Reverse polarity protection
4.1.5.
When reverse connected, the screen LED will flash and the output power will be cut off. This protection will protect both the charger
and the battery from damage. If you have accidentally made a reverse polarity connection, please switch battery charger off from AC
power, and correct the battery clamp connections to the correct polarities.
4.1.6.
Short circuit protection
No output when clamps are connected together, power output only occurs when connected to a battery. This prevents charger
malfunction if clamps accidentally come in contact with each other.
4.2.
BATTERY CHARGING INSTRUCTIONS
4.2.1.
Step 1. Connect battery charger cables to battery charger, using the supplied nuts to the correct polarity terminals on the front of the
charger – (Red + Positive) / (Black – Negative). Please DO NOT over-tighten nuts on front panel.
4.2.2.
Step 2. Electrolyte Level Check (where applicable). For sealed maintenance free batteries check the state of charge indicator.
NOTE:
Refer to the vehicles manufacturers' owner manual.
4.2.3.
Step 3. Connect battery charger to battery.
NOTE:
Refer to the vehicles manufacturers' owner manual.
Ensure the battery is in a safe location on a stable surface with adequate ventilation.
Ensure the correct Personal Protective Equipment is being worn i.e. Gloves and Eye Wear.
Plug the battery charger into the mains power source ensuring that the power is OFF.
Connect the RED lead (Battery Clamp) to the Positive Terminal (+/positive) on the battery.
Connect the BLACK lead (Battery Clamp) to the Negative Terminal (-/negative) on the battery or to a metal grounded non-moving part
of the vehicle.
Turn the mains power source ON, and switch the power switch on the rear of the unit to ON to commence charging.
4.3.
LITHIUM BATTERY ONLY – Press and hold MODE button for 3 seconds until LITHIUM LED indicator lights up. Lithium Mode
will automatically turn off when charger power is disconnected.
The battery charger will commence working automatically without the need for any further user input. Once the battery is fully charged
turn the power switch on the rear of the unit OFF, and disconnect the mains power source.
Disconnect the BLACK lead (Battery Clip) from the Negative Terminal (-/negative).
Disconnect the RED lead (Battery Clip) from the Positive Terminal (+/positive).
Refit battery into vehicle and correctly reconnect using the vehicle manufacturer's recommendations, or If required, replace or tighten
the vent caps on the battery
Step 4. Charging Sequence
4.3.1.
•
Once connected the LED Battery Charge display will illuminate and show:
•
Charging Voltage
•
Percentage of Charge
•
Charging output current
•
Lithium mode (on or off)
•
Power Supply mode (on or off)
•
Charging Stage progress (charging graph)
•
If there is a fault with the battery or one of the battery's cells, the battery charger will automatically switch off; no charge will be sent to
the battery.
•
If the battery leads are placed on the reverse polarity terminals of the battery the Screen LED will flash, indicating that the battery
charger has been incorrectly connected to the battery. Immediately disconnect the battery charger from the battery terminals and
correctly fit the battery cables to the correct battery terminals.
4.4.
CHARGING STAGES
4.4.1.
Analysis / Desulphation
A small voltage pulse is applied to the battery to ensure it can effectively and safely accept a charge. Desulphation uses pulse
reconditioning to gently remove any sulphation build up on the battery plates and prevents oxidization. Stabilizes electrolyte
consistency and minimises the battery temperature rising while charging, recovers battery capacity and can help extend battery life.
Soft Start
The soft start function improves the batteries charging capability, reduces gas and heat build-up and can improve electrolyte
consistency which can become uneven in the battery's cells from day to day use. A steadily increasing current is applied over a set
time so as not to initially overload the battery. This stage prepares the battery for the more intense charging stages to follow.
Bulk charge
4.4.2.
Maximum charge current is delivered to the battery to minimize charge times.
