Overview
The connections of the charger may contain a maximum of 15V.
Non-rechargeable batteries may not be charged with this equipment.
Mains- and charger units must be kept out of children’s reach.
In commercial facilities, the Health and Safety Regulations relating to electdcal work carried
out, must be followed.
In schools, educational facilities, hobby- and DIY workshops it is recommended that the
usage of mains- and charger units are supervised by trained personnel.
l&LEAD .
Lead acid accumulators consist of two electrodes, which are housed in ‘an electrolyte,
therefore an accumulator is a chemical element inside which chemical reactions are
occurring. Due to the reversible nature of these processes, accumulators can be recharged.
This accumulator is designed for charging lead acid accumulators. In lead acid accumulators
the positive electrode consists of lead oxide and the negative electrode of metallic lead.
Diluted sulphuric acid is used as an electrolyte.
The voltage of a lead acid accumulator cell is 2V. The total voltage for the accumulator is:
amount of cells x 2V. Most manufactured lead acid accumulators carry a voltage of 2V, 6V
and 12V. Unloaded this voltage may be greater. During charging the voltage drops
dependent on the condition of the accumulator. This is caused by its inner resistance.
When opening casing or dismantling parts, voltage laden components are being released.
Connecting points may also be loaded. Before an adjustment, service, installation or
exchange of parts, the equipment must be disconnected from all electrical sources.
Opening of the housing and exchange of parts of the equipment, adjustment, service or
installation must be carried out by a qualified electrtcianlengineer, who is aware of possible
dangers and Health and Safety Regulations.
Condensators inside the device may still be charged, even after the appliance has been
disconnected from all electrical sources.
It must be ensured that only fuses of the correct type and the correct rated voltage are being
used as replacements. The use of repaired fuses or bridghg of the safety bracket is
inadmissible.
II! ATTENTION Ill
To charge an accumulator, the so-called ‘loading capacity’ is needed, which is greater than
the ‘no load’ voltage. In addition, the amount of the voltage-input must be higher than the
charge which is withdrawn thereafter. This relation of supplied and used charge is called
‘charging factor’.
The withdrawn capacity, which largely depends on the electric discharge, directly affects
the condition of the accumulator. The charge input cannot be used as a form of measure
as part of it gets lost i.e. transformed into heat.
The capacity which is printed on the accumulator, is the maximal theoretical charge amount
which the accumulator can produce. This means that an accumulator with 7,2Ah can
theoretically produce electricity of 360 mA over 20 hours. These values depend very strongly
on various factors (i.e. condition of accumulator, discharged electricity, temperature etc.).
,The term c-rate is used widely when dealing with charging batteries. The c-rate is the value
of electricity, which is normally used for charging and discharging. This electric value
measured in amperes, equals the rated capacity in ampere hours, for example the c-rate
of an accumulator with 7,2Ah equals c=7,2A.
Storage batteries can discharge themselves over a period of time. This characteristic is
named ‘independent discharge’.

Exchange of fuses may only be carried out by a qualified electrician who is familiar with
possible dangers.
Never switch on your appliance immediately after it has been brought in from a cold room
to a warm place. This causes condensation which could destroy your device under
unfavourable circumstances. Keep your appliance switched off until it has adapted to room
temperature.
The wearing of metallic or conductive jewellery such as necklaces, bracelets, rings etc.
when working with mains- and charging devices is forbidden.
It is forbidden to use charging devices on humans and animals.
During use, care should be taken-to provide sufficient ventilation. The ventilation slits of
the housing unit must never be covered. The device is to be run in such a way that air can
circulate freely. Cooling of the appliance ensues mainly through convection (circulation of
warm air).
Charging devices and their connected accu-packs may not be used without supervision.

When working with charged components, only tools which are specifically designed for
such a purpose may be used.
Should the situation arise that safe use of the device is no longer possible, it must be placed
‘out of order’ and secured against possible further use.
The above mentioned applies:
- if the appliance shows visible damage
- if the appliance no longer works
- affer heavy transportation stress
A damaged mains plug (adapter) cannot be replaced; the device does no longer function.
Only use the appliance in dry, closed rooms.
The device may only be run at environmental temperatures of +lO”C to +35”C.
3, CHARACTERlSrlCS
This is a quick mode charging device for lead acid accumulators with a rated capacity of
12V and a loading capacity of 2,7A. Dependent on the accumulator manufacturer, the
minimum capacity ranges from 7,2Ah to 1lAh. The accumulator which is to be loaded
should not exceed a capacity of 60Ah.
The charger unit works in three different modes. An LED indicator light with three different
colours shows the mode the charge is in. Unlike the so-called ‘taper chargers’ (chargers
with constant voltage), this model charges with a constant current in the first mode. When
the battery voltage during charging reaches 14,7V (max. cycle voltage) the charger does not
change immediately to standby-mode. Instead, the charger starts a timer and remains in
constant voltage mode (14,7V) for a preset period of time (2 hours). By the time the timer
is started, the battery is already charged to 70-95% of the full capacity.
The time-boost period at 14.N ensures. that the remaining 5-30% capacity is charged
within a short time. The LED display changes from red to yellow when the timer starts and
then to green when the pre-set time (2 hours) has elapsed. At this point the constant voltage
level is reduced to 13,8V at which the battery can be left without risk of overcharging and
to avoid resulting production of gases within the accumulator. The accumulator can remain
connected constantly to the charger, without resulting damage. This mode is called
‘Standby’.
A new charging cycle begins when the charging current rises to the constant current level
(approx. 2.7A). This occurs when the battery voltage drops due to loading of the battery.
It is unnecessary to discharge this appliance before recharging. The lead acid accumulator
will fully recharge from its present charging condition to 100% .
The type of lead acid accumulator used in this charger is of importance. Make sure only
lead acid accu-packs with a rated capacity of 12V are connected to this unit. Ensure the lead
acid accu-pack to be charged is suitable for a charging with 2,7A. If in doubt, check with
your supplier.

LED Display
The three-coloured LED display installed in the charging device signals the following
operations:-
* RED
the charger is in constant current mode with a maximum charge
current (approx. 2,7A). The battery voltage is lower than than the cycle
voltage level (<14,7V).
l YELLOW
l GREEN
the charger is in time/constant cycle voltage mode. The charge current
is lower than the maximum value (e2.7A). Battery voltage equals cycle
voltage level (=14,7V). The charger remains in this mode until pre-set
time (2 hours) has elapsed.
the charger is positioned in float charge mode. The charge current is
usually very low (<<2.7A). The charge voltage is equivalent to a float/
standbychargeofabout 13,8V. The batteryisfullyloaded to 100%. The
charger will switch to quick charge mode, when the battery is loaded.
In this mode, the battery can be left connected to the charger
indefinitely.
The charger unit is fitted with an internal inert fuse (cut-out) of 1,6A, which will bum out in
case of a charger fault. Damages of this kind may only be repaired by qualified technical
personnel.
!!I ADVICE: Sulphate batteries Ill
Older sulphate batteries usually have a diminished capacity and are difficult to recharge.
The charge current will diminish rapidly, just as if the battery had been fully loaded. Although
this kind of battery is able to store a minimal wattage it should be replaced.

DPERATINGINSTRUCTIONS
III WARNING It!
Explosive gases, Avoid fire and sparking. Be aware that sufficient ventilation is available
during the charging process.
Battery acid is strongly corrosive. If acid comes into contact with clothing, rinse immediately
under running water. If acid comes into contact with skin or eyes, rinse affected areas
immediately under plenty of running water. If necessary consult a doctor.
LOADING INSTRUCTIONS
Refillable lead acid batteries: Check the electrolyte level ofthe accumulator. If necessary,
fill up with distilled water to 5-IOmm above the plates
observing safety instructions.
Ensure that the accumulator is not sulphated or affected by a short-circuit of the inner cells.
Only insert plug of the charger unit into the socket, after the accumulator has been
connected. This avoids sparking which could possibly cause ignition.of flammable gases.

L
Take note of the polarity and connect the correct conductor leads of the charger to the
corresponding terminal of the accumulator. This means, connect the positive terminal (+)
of the charging unit (red wire) to the positive terminal (+) of the accumulator and the negative
terminal (-) of the charging unit to the negative terminal (-) of the accumulator If loading
an accumulator which is already fitted in the vehicle, connect the accu terminal (connected
to vehicle chassis) to the chassis of the charger last.
Connect the corresponding charger conductor to the chassis of the vehicle, keeping
sufficient distant to the accumulator and all fuel leads.
Only now one may insert the mainsplug into the socket.
After the charging process has finished, the charger plug must be disconnected first. Only
then the connection cable of the battery may be removed. When loading a battery which is
built into the vehicle, unplug the charging cable fitted to the chassis of the vehicle, first.

which are suitable for a rated voltage of 12V must be used . Other types may not be charged.
If in doubt, consult with accumulator supplier.
A continuous red LED indicator light will show that quick-charge is in progress when the
constant voltage level is less than the maximum voltage, the LED changes to yellow. The
battery is now loaded up to 70-95% of its capacity. After completion of the full loading Cycle,
the LED display switches to the colour ‘green’. The accumulator is now fully charged.
III Advice III
Used or damaged accu-packs do not belong in the rubbish bin!
For reasons of environmental safety, accus must be disposed off in battery-collection bins,
which should be available in every reputable electrical appliance store or recycling centre.

R&urn&
Une battetie est constitue de deux electrodes, qui sont plades dans une dlectrolyse. nous
obtenons une reaction chimique. Ce processus chimique est reversible, c’est ainsi que
les accumulateurs peuvent &tre charges.
Le chargeur sert a charger des batterie au plomb. Ce type de batterie se compose dune
electrode positive d’hydroxyde de plomb et d’une electrode negative de metal de plomb.
L’electrolyte est composee d’acide sulfurtque.
La tension d’une cellule est de 2 volts.La tension totale de la batterie est de 2V x le nombre
de dllules. Les tension les plus repandues sont de 2V, 6V,12V. Sans charge est cette
tension globalement plus grande. En charge, la tension diminue plus ou mains rapidement
selon I’etat de la batterie.
Pour charger une batterie, on utilise une tension appelee tension de charge, qui est
superieure a la tension de repos, ainsi la tension de charge est plus Blevee, que c’elle
pouvant &tre accumulee. Ce rapport entre ces deux valeurs est appele facteur de charge.
La capacite accumulee, qui depend directemnet du courant de charge est determinant pour
le bon &at des accumulateurs. Ce facteur de charge ne peut 6tre considere comme regle
absolue &ant donne qu’une partie sera transform&e en perte (Ex.: en chaleur etc.).
La capacite ins&e sur les accumulateurs correspond theorlquement a la quantite de
courant disponible, ainsi une batterie de 7,2Ah peut foumir en theorie pendant une duree
de vingt heures un courant de 36OmA. Cette valeur depend de I’btat des accumulateurs,
du courant de sortie, de la temperature etc.
Ainsi pour cette valeur sera utilise I’appelation . c’, qui correspond au courant de charge
et de d&charge. Ce rapport est interpret& en amperes /charge et en amperes- heures pour
la d&charge, ainsi pour un accumulateur de 7,2Ah : C=7,2A.
Avec le temps les accumulateurs se dechargent, dans ce cas on parle d’autodecharge.
