Calculating the Charging Time
The charging time
depends on the
charge status of the
battery. If the battery
is fully discharged, the
approximate charging
time up to approx.
80% charged can be
calculated using the
following formula:
Note: The charging current should be 1/10 to 1/6 of the battery
capacity.
Overload Cut-Out
The charger has electronic protection against overloading, short-
circuits and swapped poles when the 12V STD, 12V AGM, 12V
Winter and 12V M programs are used. One or more fine fuses are
also fitted. If the fuse suffers a defect it must be replaced by a new
fuse with the same amp value. If necessary, please contact Ozito

WARNING! DO NOT USE FOR CHARGING LITHIUM ION
PHOSPHATE RECHARGEABLE BATTERIES (E.G. LiFePO4)
OR OTHER LITHIUM RECHARGEABLE BATTERIES.
The battery charger is a microprocessor controlled automatic
charger, it is suitable in particular for charging maintenance-free
batteries and for the long-term charging and maintenance-
charging of batteries which are not in constant use, e.g. for
classic cars, recreational vehicles, lawn tractors and alike. The
integrated microprocessor enables charging in several steps. The
final charging step, maintenance charging, maintains the battery
capacity at 95–100% and therefore keeps the battery fully charged
at all times. The charging operation does not need to be monitored.
However, do not leave the battery unattended if you charge it over
an extended period of time, so that you can disconnect it from the
mains power supply in the event of a fault in the charger.
The battery charger is designed for mobile use only and not for
installation in caravans, mobile homes or similar vehicles. Do not
expose the charger to rain or snow.

Connecting to a Vehicle Battery
Before charging make sure the battery terminals are really clean
as grease and dust could lead to poor connection. The battery
MUST be disconnected prior to cleaning. Check the battery and
connections for any cracks or damage before proceeding with
cleaning and charging. To help ensure a good connection of the
battery charger terminal clamps, clean the battery terminals with a
solution of baking soda and water, and wipe the battery terminals
with a cloth to remove any dirt and grease.
If the battery is still fitted to a motor vehicle, make sure that all the
electronics are turned OFF, and that the ignition is turned OFF.
1. With the vehicle engine not
running, connect the red
positive terminal clamp to
the positive ( + ) pole on your
vehicle 12V battery.
Note: The charger draws a very small amount of electricity from
the battery and the LCD comes on briefly. This is not a fault.
2. Connect the black negative
terminal clamp to an
unpainted piece of metal on
the bodywork away from the
battery.
3. Connect the charger to a
mains power socket.
