FEATURES

• Button-less automatic battery voltage selection. This charger is suitable
for 6 Volt, 12 Volt and 24 Volt DC automotive batteries. When the charger
is connected to a battery and switched on, the unit will take approximately
1 minute to test and initialise the correct voltage program. This occurs
automatically with no user input required.
• Button-less automatic battery chemistry selection, suitable for GEL, LEAD ACID,
AGM, and Maintenance Free, Calcium types of automotive batteries. To charge
12V lithium batteries, please hold the mode button for 3 seconds to switch to
12V Lithium charging. This will display on the LED screen.
WARNING: Do not attempt to recharge dry cell batteries.
• Large easy to read LED display shows the charging stage status, volts and amps
output and battery capacity.
• Inbuilt protection systems for safe operation.
• Zero volt start up, enabling recovery and charging of a completely deep
discharged battery. But any load must be removed from the rechargeable
battery.
• 13.5V DC power supply for 8A, 12A and 16A output currents with overload and
short circuit protection.
• Internal or external short circuit, reverse connection (Yellow LED), over
temperature, overload and over voltage protection.
• For these products, the charger can be hung with a hook, and the power cable
can be wound on the back.

OPERATING INSTRUCTIONS

Charging Process:
Fully automatic 7 stage charging system:
• Analysis / Desulphation (Charging stage 1 illuminated) – 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. Stabilises
electrolyte consistency and minimises the battery temperature rising by
charging, recovers battery capacity and can help extend battery life.
• Soft Start (Charging stage 2 illuminated) – 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 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.
