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).
• Pay attention to the operation instruction and
fix them close to the battery.
• Work on batteries to be carried out by skilled
personnel only!
• Use protective glasses and clothes when wor-
king on batteries. Pay attention to the accident
prevention rules as well as DIN EN 50272-3 and
DIN EN 50110-1.
• No smoking!
• Do not expose batteries to naked flames,
glowing embers or sparks, as it may cause the
battery to explode.
• Acid splashes in the eyes or on the skin must be
washed with water. In case of accident consult
a doctor immediately!
• Clothing contaminated by acid should be
washed in water.
• Risk of explosion and fire, avoid short circuits!
• Caution: Metal parts of the battery are always
live. Do not place tools or other metal objects
on the battery!
• Electrolyte is highly corrosive.
• Batteries and cells are heavy.
• Ensure secure installation! Use only suitable
handling equipment e.g. lifting gear in accor-
dance with VDI 3616.
• Dangerous electrical voltage!
• Pay attention to the hazards that can be caused
by batteries.
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 replace-
ment 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 it is below the anti-surge baffle or 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 Oerlikon 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.
