SETUP & PREPARATION

AUTOMATIC CHARGING

WARNING! READ AND UNDERSTAND THE WARNINGS BEFORE SETUP AND CHARGING.

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 that 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.

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:

Ah	80%
8	2h
20	5 h
40	10 h
80	20 h

Charging time/hours = Battery capacity in Ah/ Amperes (charging current)

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, shortcircuits, 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 customer service.
