USER MANUAL FREN
Before beginning to charge check that the capacity of the battery (Ah) to charge is not inferior to that indicated on the
appliance.
1) Remove the battery’s caps (if not sealed) so that the gas produced can escape. Check that the level of the electrolytic
liquid covers the battery’s elements; otherwise add some distilled water up to 5 to 10 mm above the elements. Note that
the condition of charge of a battery is given by a battery hydrometer. The following density values (kg/l at 20°C) give
reference marks:
1.28 = battery charged
1.21 = half charged
1.14 = battery discharged
An off-load battery output inferior to 9V for a 12V battery indicates an insufficient charge.
Caution: take precautions when handling batteries, the electrolyte is a very corrosive and dangerous product.
2) The power supply cable not being plugged into the power supply, select with the switch (option according to model)
the voltage of the battery to charge.
3) Put the red cable pliers on the (+) terminal of the battery and the black cable pliers on the (-) terminal;
Comment: If the battery is charged in place, first connect the charging cable to the battery terminal that is not grounded
(car body), the other connection should be done on the car body, far from the battery and fuel pipes.
Plug the power supply cable into the electric source and switch the main button to the“ON”position. The ammeter
indicates the current sent to the battery (beginning of charge); during the load the pointer deflects slowly towards very
small current values, depending on the battery.
When the battery is completely charged, the liquid starts to boil; charging should be stopped as soon as the boiling starts
to keep the battery in good condition and to avoid risks of explosion of the gasses emitted.
Comment:
Case of “no maintenance”type batteries, often sealed.
Charging should be carried out with the greatest vigilance possible.
Charge slowly and closely watch the voltage at the battery’s terminals with a multimeter (not supplied).
Stop the charging when you obtain the following values: 7.2 V for a 6V battery, 14.4 V for a 12V battery and 28.8V for a 24V
battery.
Simultaneously charging several batteries
Serial or parallel connections are used to simultaneously charge several batteries. A serial connection is preferable for it
allows controlling with the ammeter the current passing in each of the batteries.
Note: For the serial connection of 2 batteries the voltage selected should be doubled,
Example: for two 12V batteries select 24V.
End of charge: When the charging is finished, first put the main switch on the OFF position “O” and unplug the power
supply cable from the electric source. Then remove the cable pliers from the battery’s terminals. Do not forget to put the
caps back on the battery.
Comment: if the battery is charged in place, after having unplugged the power supply cable from the electric source first
remove the charger cable on the grounded terminal (car body). Protection (options according to model)
The fuse protects:
- From overloads (too much current supplied to the battery);
- From short-circuits between the cable pliers;
- From inversed polarities of the battery
A burnt fuse should be replaced with an exactly identical fuse otherwise serious risk of accident to people and
deteriorations of equipment are probable.
The replacement of a fuse is done with the charger unplugged from an electrical source and not connected to a battery.
BEFORE STARTING TO CHARGE:

Safety instructions:
- The appliance should be used in well ventilated premises to avoid the accumulation of gasses. Outdoor use is prohibited.
- Remove the caps from the battery’s elements before beginning to charge
- Check that the level of the electrolytic liquid covers the battery’s elements; otherwise add distilled water up to the level
indicated on the battery.
- Do not touch the battery’s electrolytic liquid it is very corrosive.
- Clean the battery’s terminals to ensure correct contact with the pliers.
- Avoid contact between the pliers when the charger is operating.
- If the charger is used for a battery that remains installed on a vehicle, comply with the instructions of the vehicle’s
manufacturer.
- Check that the charger’s features are compatible with the battery and the power supply network, a grounded power
outlet is necessary.
- Do not expose the appliance to rain, snow and/or humidity;
- The appliance and the battery should be used far from any flame and sparks, do not smoke
- Only charge rechargeable batteries. The charging of non-rechargeable batteries or other products is prohibited.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the
appliance by a person responsible for their safety.
The battery terminal not connected to the chassis has to be connected first, the other connection is to be made to the
chassis, remote from the battery and fuel line.
The battery charger is then to be connected to the supply mains.
After charging, disconnect the battery charger from the supply mains.
Then remove the chassis connection and the battery connection.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in
order to avoid a hazard.
