FEATURES
Automatic Charging
When in automatic mode the charger will stop charging the battery when the battery is fully charged.
You can leave the charger connected to the battery without risk of overcharging. Once the battery is full,
the battery charger will automatically start to maintain the battery. The charger monitors the battery voltage
and continues to top up the battery, keeping it fully charged and ready for use.
Manual Charging
The charger in this mode will continue to charge the battery until the timer finishes or is turned off and
requires the user to monitor the charging battery. When used by experienced users it can deliver an
equalization charge to balance the voltage in the battery's cells.

LED Voltage/Amp Display
The charger has a VOLT and AMP meter built in. When the charger is initially powered up the display will
show voltage. When the VOLT / AMP button is pressed the Amps will be displayed, press the button again
the display will go back to Volts. When Volts is displayed this indicates the state of charge of the battery,
when Amps is displayed this indicates how much charge is being accepted by the battery.
Override Button
The battery charger measures the battery voltage at the clamps to determine if the battery is correctly
connected. A reading above 3V will activate the battery charger. In some instances where the battery is
extremely flat, it is possible to have correct connection and the battery to be below the 3V limit. In this
instance check the battery leads to ensure they are connected correctly and press the OVERRIDE button
to activate the battery charger.
Multi Voltage
Suitable for charging 6V, 12V & 24V batteries.
