Operating Instruction
Stationary, valve regulated lead acid batteries
(VRLA/AGM)
Description / Type:
RPower / OGiV
Valve-regulated lead acid batteries consist of cells
which do not require water topping during the
operation. For plugs there are used pressure control
valves, which can not be opened without
destruction.
1. Start up
Check all cells/blocks for mechanical damage,
correct polarity and firmly seated connectors.
The following torques apply for screw connectors:
M5
M6
M8
M 10
2 - 3 Nm
4 - 5,5 Nm
5 - 6 Nm
14-22 Nm
If necessary the terminal cover are to be raised.
Connect the battery with the correct polarity to the
charger. The charger should not be switched on
during this process, the load should not be
connected (pos. pole to pos. terminal). Switch on
charger and start charging following instruction no
2.2.
2. Operation
For the installation and operation of the batteries
DIN VDE 0510 is mandatory. Battery installation
should be made such that temperature difference
between individual units does not exceed 3 degrees
Celsius/Kelvin.
2.1 Discharge
Discharge must not be continued beyond the level
specified for the specific discharge current. Deeper
discharges must not occur unless specifically
agreed
with
the
manufacturer.
Recharge
immediately following complete or partial discharge.
2.2 Charging
Applicable are all charging procedures with their
limit values according to DIN 41773 (IUU
0
-
characteristic).
According
to
the
charging
equipment
specification
and
characteristics,
alternating currents (< 0,1C(A)) flow through the
battery super-imposing into the direct current during
charging operation. These alternating current and
the reaction form the loads lead to an additional
temperature increase of the battery,
and strain the electrodes with possible damages
(see 2.5). Depending on the installation, charging
(acc. to DIN VDE 0510 part 1, draft) may be carried
out in the following operations.
a) Standby Parallel Operation
and Buffer Operation
Here the load, direct current source and battery are
continuously in parallel. Thereby the charging
voltage is the operation voltage and at the same
time the battery installation voltage. With the
standby parallel operation, the direct current source
is at any time capable of supplying the maximum
load current. The battery only supplies current
when the direct current source fails. The charging
voltage should be set at 2,275V ± 0,005V (20°C) x
number of cells in series measured at the terminals
of the battery.
With buffer operation, the direct current source is
not able to supply the maximum load-current at all
times. The load current intermittently exceeds the
nominal current of the direct source. During this
period the battery supplies power. The battery is
not fully charged at all times but the float-charge of
2,275 V/cell ±0,005V (20°C) x number of cells in
series provides a reasonable recharge duration
under normal conditions. Dependent on load and
number of cells in series, it is recommended to
consult the battery manufacturer in any doubtful
case.
b) Switch-mode-operation
When charging, the battery is separated from the
load. To reduce the charging time, a three phase
boost charge mode can be applied by charging the
battery at 2,45 - 2,5 V/cell until the charging current
drops to 0,07 C(A) (trip point for the first phase of
charging t1). The duration of charging of the first
phase is measured by a timer so that the second
phase should be half of the first phase (t2 = 0,5 t1)
when the batteries are kept on charger at 2,45
2,5V/cell. After the total charging of t=t1+0,5t1 has
elapsed, the charger reduces the voltage to a
normal float-charge level of 2,275V/cell (±0,005V)
at 20°C.
c) Battery operation
(charge/discharge operation)
The load is only supplied by the battery. The
charging process depends on the application and
must be carried out in accordance with the
recommendations of the battery manufacturer.
2.3 Maintaining the full charge
(float charge)
Devices complying with the stipulations under DIN
41773 must be used. They are to be set that the
average cell voltage is 2.275V±0,005V.
2.4 Supplementary and Equalizing charge
To ensure maximum service life, a supplementary
charge may be required prior to installation on
condition that the batteries have been in storage for
more than 6 months or more, latest after 9 months
age from the date of production and that the open
circuit voltage is less than 2,1 Volts per cell. A
supplementary charge should be applied in
accordance with figures shown in the table:
• Nominal voltage UN:
Cells 2V:
Cells 12V:
• Nominal capacity C20:

• Nominal temperature TN:

•
Observe these Instructions and keep them located near the battery for future reference.
•
Work on the battery should be carried out by qualified personnel only.
•
Do not smoke. Do not use any naked flame or other sources of ignition. Risk of explosion
and fire.
•
While working on batteries wear protective eye-glasses and clothing.
•
Observe the accident prevention rules as well as EN 50272-2, DIN VDE 0510, VDE 0105
Part 1.
•
Any acid splashes on the skin or in the eyes must be flushed with plenty of clean water
immediately. Then seek for medical assistance. Spillages on clothing should be rinsed out of
water.
•
Explosion and fire hazard, avoid short circuits.
•
Electrolyte is very corrosive. In normal working conditions contact with the electrolyte is
impossible. If the cell or monobloc container is damaged do not touch the exposed
electrolyte because it is corrosive.
•
Cells/bloc batteries are heavy! Always use suitable handling equipment for transportation.
Handle with care because bloc batteries are sensitive to mechanical shock.
Non-compliance with operating instructions, repairs made with other than original parts,
or repairs made without authorization (e. g. opening of valves) render the warranty void.
Disposal of batteries
Batteries marked with the recycling symbol should be processed via a recognized
recycling agency. By agreement, they may be returned to the manufacturer.
Batteries must not be mixed with domestic or industrial waste.
