Ignoring the operation instructions, repair with non-original parts or using additives for the electrolyte will render the
warranty void.
For batteries according to the ATEX directive 94/9 EC, the instructions for maintaining the appropriate protection class
during operation must be complied with (see relevant certificate).
1. Commissioning filled and charged batteries
For commissioning of unfilled batteries see separate
instructions! The battery should be inspected to ensure it is in
perfect physical condition.
The charger cables must be connected to ensure a good
contact, taking care that the polarity is correct.
Otherwise battery, vehicle or charger could be damaged.
For the assembly of harness cables or in case of the replacement of a connector the following torque must be applied:
M 10 perfect connector
25 ± 2 Nm
In case the interval between delivery (see manufacturing date
on type plate) and commissioning is longer than 8 weeks or
the electrolyte level sensor is indicating low electrolyte level
(see table point 3.1.1 ), the electrolyte level has to be checked.
If the battery is equipped with a single point water topping up
system (optional), for the removal of the BFS plugs only the
appropriate tool must be used. Otherwise the floats of plugs
may be permanently damaged, which can cause overflow
of the cells. If the electrolyte level is below the top of the
separator, it must first be topped up to this height with
purified water (DIN EN 43530-4).
The battery is then charged as in item 2.2.
The electrolyte should be topped up to the specified level
with purified water.
2. Operation
DIN EN 50272-3 “Traction batteries for industrial trucks” is the
standard which applies to the operation traction batteries in
industrial trucks.
2.1 Discharging
Be sure that all ventilation holes are not sealed or covered.
Electrical connections (e.g. plugs) must only be made or
broken in the open circuit condition. To achieve the optimum
life for the battery, operating discharges of more than 80% of
the rated capacity should be avoided (deep discharge). This
corresponds to an electrolyte specific gravity of 1.14 kg/l at
30°C at the end of the discharge. Discharged batteries must
be recharged immediately and must not be left discharged.
This also applies to partially discharged batteries.
2.2 Charging
Only direct current must be used for charging.
For the Hawker Perfect Plus batteries, procedures in
accordance with DIN EN 41773-1 and DIN EN 41774 are
permitted. Only connect the battery assigned to a charger,
suitable for the size of battery, in order to avoid overloading
of the electric cables and contacts, unacceptable gassing and
the escape of electrolyte from the cells. In the gassing stage
the current limits given in DIN EN 50272-3 must not be
exceeded. If the charger was not purchased together with
the battery it is best to have its suitability checked by the
manufacturers service department. When charging, proper
provision must be made for venting of the charging gases.
Doors, battery container lids and covers of battery
compartments must be opened or removed. During the
charge the battery must be removed from the closed battery
compartment on the truck. The ventilation must comply to
DIN EN 50272-3 standard. The vent plugs should stay on the
cells and remain closed. With the charger switched off
connect up the battery, ensuring that the polarity is correct.
(positive to positive, negative to negative). Now switch on the
charger. When charging the temperature of the electrolyte
rises by about 10°C, so charging should only begin if the
electrolyte temperature is below 45°C. The electrolyte
temperature of batteries should be at least +10°C before
charging otherwise a full charge will not be achieved.
A charge is finished when the specific gravity of the
electrolyte and the battery voltage have remained constant
for two hours. Batteries fitted with electrolyte circulation
system: if the warning light on the pump controller is
illuminated or if a defect signal on the electrolyte mixing
system appears, check that the piping system is connected
and examine the piping circuit for leaks or defects.
(see 3.4. Maintenance)
The air pipe should never be removed during charge.a
pay particular attention to the battery charging plugs and
cables. By special applications with charge with a IU
characteristic curve an equalising charge must be carried out
(see point 2.3).
3.3 Monthly
At the end of the charge the voltages of all cells or bloc
batteries should be measured with the charger switched on,
and recorded. After charging has been completed, the
electrolyte density, electrolyte temperature as well as the
filling level (when filling level sensors are used) of all cells are
to be measured and recorded.If significant changes from
earlier measurements or differences between the cells or
bloc batteries are found further testing and maintenance
by the service department should be requested.
This should be done following a complete charge and
minimum of 2 hours rest time.
Measure and record:
• total voltage
• voltage per cell
• if the voltage readings are irregular, also check the S.G. of
each cell
2.3 Equalising charge
3.4 Annually
Equalising charges are used to safeguard the life of the
battery and to maintain its capacity. They are necessary after
deep discharges, repeated incomplete recharges and charges
to an IU characteristic curve. Equalising charges are carried
out following normal charging. The charging current must
not exceed 5 A/100 Ah of rated capacity (end of charge - see
point 2.2). Watch the temperature!
2.4 Temperature
An electrolyte temperature of 30°C is specified as the rated
temperature. Higher temperatures shorten the life of the
battery, lower temperatures reduce the capacity available.
55°C is the upper temperature limit and is not acceptable
as an operating temperature.
2.5 Electrolyte
The rated specific gravity (S. G.) of the electrolyte is related to
a temperature of 30°C and the nominal electrolyte level
in the cell in fully charged condition.
Higher temperatures reduce the specified gravity of the
electrolyte, lower temperatures increase it. The temperature
correction factor is -0.0007 kg/l per °C, e.g. an electrolyte
specific gravity of 1.28 kg/l at 45°C corresponds to an
S.G. of 1.29 kg/l at 30°C. The electrolyte must conform to the
purity regulations in DIN EN 43530-2.
3. Maintenance
3.1 Daily
Charge the battery after every discharge. Hawker Perfect Plus/
Perfect Plus with electrolyte circulation: towards the end of
charge the electrolyte level should be checked and
if necessary topped up to the specified level with purified
water (according DIN EN 43530-4). The electrolyte level must
not fall below the top of the separator or the electrolyte ”min”
level mark.
NO WATERING IN THE FIRST 10 CYCLES.
3.1.1 Filling level sensors
In the case of batteries with filling level sensors, the
illuminated LED should be observed daily.
In accordance with DIN EN 1175-1 at least once per year,
the insulation resistance of the truck and the battery must be
checked by an electrical specialist. The tests on the
insulation resistance of the battery must be conducted in
accordance with DIN EN 1987-1. The insulation resistance
of the battery thus determined must not be below a value
of 50 Ω.per Volt of nominal voltage, in compliance with
DIN EN 50272-3. For batteries up to 20 V nominal voltage
the minimum value is 1000 Ω.
Batteries fitted with electrolyte circulation system: the
filter of the air pump has to be checked during the annual
maintenance and eventually to be cleaned or replaced.
Earlier replacement of the filter is necessary if for undefined
reasons (no leaks in the air pipes) the defect signal of the air
mixing system on the charger or on the battery (on DC air
pump or remote signal) is illuminated. During the annual
maintenance, check the correct operation of the air pump.
4. Care of the battery
The battery should always be kept clean and dry to prevent
tracking currents. Cleaning must be done in accordance
with the ZVEI code of practice “The Cleaning of Vehicle
Traction batteries”. Any liquid in the battery tray must be
extracted and disposed of in the prescribed manner. Damage
to the insulation of the tray should be repaired after
cleaning, to ensure that the insulation value complies with
DIN EN 50272-3 and to prevent tray corrosion. If it is
necessary to remove cells it is best to call in our service
department for this.
5. Storage
If batteries are taken out of service for a lengthy period
they should be stored in the fully charged condition in a dry,
frost-free room. To ensure the battery is always ready for use
a choice of charging methods can be made:
1. a monthly equalising charge as in point 2.3, or
2. float charging at a charging voltage of 2.27 V x the number
of cells.
The storage time should be taken into account when
considering the life of the battery.
6. Malfunctions
LED green
LED red blinking
level OK
level too low
Do not top up the cells even when electrolyte level sensor
shows a red blinking LED during first 10 cycles.
Check the electrolyte level (visual inspection by opening
the vent plug or by the position of the float indicator of the
aquamatic plug) and top-up with demineralised water at the
end of the charge.
Since the display always refers to a selected reference cell,
please also pay attention to the additional instructions under
“3.3 Monthly Maintenance.”
3.2 Weekly
Visual inspection after recharging for signs of dirt and
mechanical damage to all component parts of the battery,
If malfunctions are found on the battery or the charger our
service department should be called in without delay. The
measurements taken in point 3.3 will facilitate fault finding
and their elimination.
A service contract with us will make it easier to detect and
correct faults in good time.
OPTIONS
Aquamatic water refilling system (optional accessory)
1. Application
2.3 Working pressure
The water refilling system is used to automatically maintain
the nominal electrolyte levels.
The charging gasses escape through the vent on each cell.
NO WATERING IN THE FIRST 10 CYCLES.
The water refilling system should be installed in such a way
that a water pressure of 0.2 to 0.6 bar is obtained (with at least
2 m height difference between the upper edge of the battery
and the lower edge of the tank). Any deviation from this
means that the system will not function properly.
2. Function
2.4 Purity
A valve and a float together control the topping up process
and maintain the correct water level in each dell. The valve
allows the flow of water into each cell and the float closes the
valve when the correct water level has been reached.
For fault-free operation of the water refilling system, please
note the instructions below:
The topping up water must be purified. The water used to
refill the batteries must have a conductance of not more
than 30 µS/ cm. The tank and pipes must be cleaned before
operating the system.
2.5 Pipe system on the battery
2.1 Manual or automatic connection
The battery should be topped up shortly before completion
of a full charge, as at this point the battery has reached a
defined operational state resulting in satisfactory electrolyte
mixing. Filling takes place when the connector (7) from the
tank is connected to the coupling (6) on the battery.
2.1.1
2.1.2
2.1.3
If manual connection is used the battery should only
be connected to the filling system once a week
(Hawker Perfect Plus).
If automatic coupling is used (with a magnetic valve
controlled by the charging apparatus) the charger
main switch selects the correct moment for filling.
Note: In this case we recommend a water refilling
at least once a week to ensure the right level of the
electrolyte (Hawker Perfect Plus).
In multiple shift and warm ambient temperature
operations, it may be necessary to have shorter
topping up intervals.
The pipe system to the individual battery cells must follow
the battery’s electrical circuit. This reduces the risk of current
leakage in the presence of electrolytic gas causing an
explosion (DIN EN 50272-3). A maximum of 20 cells may be
connected in a series.
The system should not be modified in any way.
2.6 Working temperature
In winter, batteries fitted with Aquamatic should only be
charged or refilled in a room temperature above 0 °C.
2.7 Flow control
A flow indicator built into the water supply pipe to the
battery monitors the filling process. During filling the water
flow causes the built-in disc in the flow indicator to turn.
When all the plugs are closed the disc stops, indicating that
the filling process is complete.
2.2 Filling time
Filling time depends on the utilisation rate and the
corresponding battery temperature. Generally speaking, the
top up process takes a few minutes and can vary according
to the battery range; after this, if manual filling is being used,
the water supply to the battery should be turned off.

Hawker electrolyte circulation system (optional accessory)
1. Application
2.2 Use with automatic connection of the pipe system
The electrolyte circulation system is based on the principle of
pumping air into the individual battery cells. This system
prevents electrolyte stratification and the battery charge
is optimised using a charge factor of 1.07. The electrolyte
circulation is particularly beneficial for heavy duty use, short
charge times, boost or opportunity charging and in high
ambient temperatures.
2. Function
The Hawker electrolyte circulation consists of a pipe system
fitted in the cells. A Hawker Aeromatic diaphragm pump is
fitted in the charger or separately mounted on the battery or
vehicle. This diaphragm pump sends a low rate airflow into
each cell which creates a circulating air stream inside the cell
box. The air stream is continuous or pulsed depending on the
battery voltage and pump type. The air supply is adjusted in
accordance to the number of cells in the battery.
The pipe system to the individual battery cells must follow
the existing electrical circuit. This reduces the risk of current
leakage in the presence of electrolytic gas causing an
explosion (DIN EN 50272-3).
Connecting the charge plug with integrated air supply automatically supplies air to the battery.
2.3 Maintenance of air filter
Depending on the working conditions, the pump air filter
should be changed at least once a year. In work areas with
high levels of air-pollution, the filter should be checked and
replaced more frequently.
2.4 Repair and maintenance
The system must be checked for leakage. The Hawker charger
will display an error message to indicate leakage. Sometimes
in the case of leakage the characteristic charging curve is
switched over to the characteristic standard curve (without
electrolyte mixing).
Faulty parts and faulty pipe sections must be replaced.
Only Hawker original spare parts may be used, as these are
designed for the pump air supply and will ensure correct
functioning of the pump.
2.1 Use with separate pipe system
Air is supplied when the charger pipe system is connected to
the battery pipe system (with blue ring).
