POWER ON LAMP:
If the power lamp is lit with a:
1.steady light
The mains is connected to a wall socket
2. Flashing light
The charger has entered the energy saving mode,
This happens if the charger hasn’t been connected to a battery within 2 minutes of being
turned on.
FAULT LAMP
If the fault lamp is solid,check the following
Has the charging stage been interrupted in stage 1,2 or 4?
Restart the charger by pressing the on/off button.
If the charger is still being interrupted check the battery.
STEP 1. The battery may be faulty and may need replaced.
STEP 2. Bulk charging has timed out and stopped after 10 hours of being charged.(replace
battery)
Step 3. If fault light is flashing chargers internal temperature is higher 65 oC (disconnect
charger from battery and allow fan to cool charger)

CHARGING INSTRUCTIONS
Connect the charger to the battery and turn on charger
Charger will go into diagnostic mode and check itself before beginning the charge process.
During the charge process the charging and stage lamp will flash in various patterns this
indicates the state of charge that the battery is in. When the stage lamp is on this is known
as float stage and this can be left on the battery without overcharging.
DISCONNECTING:
Turn off charger.
Remove BLACK lead from battery first , then remove RED lead from battery.
MOUNTING INSTRUCTIONS
Stage chargers are designed for indoor use out of the weather
Ensure the battery and charger are installed in a well ventilated area
During charging.
If permanently mounting the charger be sure to allow a minimum of 10 cm clearance from
end plates this will allow adequate ventilation for the cooling fan.

ALWAYS PLACE THE12V AUTOMATIC LITHIUM BATTERY
CHARGER IN AN ENVIRONMENT WHICH IS:
A. WELL VENTILATED.
B. NOT EXPOSED TO DIRECT SUNLIGHT OR HEAT SOURCE.
C. OUT OF REACH FROM CHILDREN.
D. AWAY FROM WATER / MOISTURE, OIL OR GREASE.
E. AWAY FROM ANY FLAMMABLE SUBSTANCE.
F. SECURE NO RISK OF FALLING.
ŸThe charger is designed for charging 12V Lithium-ion batteries with LiFePO4 batteries .
ŸDo not use the charger for any other purpose.
ŸCheck the charger cables prior to use. Ensure that no cracks have occurred in the cables
or in the bend protection. A charger with damaged cables must not be used.
ŸA damage cable must be replaced by a professional representative.
ŸNever charge a damaged battery.
ŸNever charge a frozen battery.
ŸNever place the charger on top of the battery when charging.
ŸAlways provide for proper ventilation during charging.
ŸAvoid covering the charger.
ŸA battery being charged could emit explosive gasses. Prevent sparks close to the
battery. When batteries are reaching the end of their lifecycle internal sparks may occur.
ŸAll batteries fail sooner or later. A battery that fails during charging is normally taken
care of by the chargers advanced control, but some rare errors in the battery could still
exist. Don’t leave any battery during charging unattended for a longer period of time.
ŸEnsure that the cabling does not jam or comes into contact with hot surfaces or sharp
edges.
ŸThis appliance is not designed for use by young children or people who cannot read or
understand the manual unless they are under the supervision of a responsible person to
