Closed lead batteries consist of cells, which do not
allow refi lling with water over the entire service life.
Relief valves are used as sealing plugs, which can
only be opened by destruction.
1. Commissioning
Before the commissioning, all blocks must be checked
for mechanical damage, correct polarity, and tight seat
of the connectors. The batteries must not be installed
at more than 2,000m. The valve cover, which covers
the relief valve, must not be taken off or taped over.
The following torques apply to screw connections:
If necessary, the pole covers are to be placed on.
Connect the battery to the DC supply with correct
polarity when the charging device is switched off and
consumers are disconnected (positive pole on posi-
tive connecting clamp), switch on the charging device
and charge according to Point 2.2.
2. Operation
EN IEC 62485-2 applies to the design and operation of
these batteries. The battery must be installed so that
between the individual blocks an environmental tem-
perature difference of > 3K cannot occur.
2.1 Discharging
The end-point voltage of the battery must not fall
below the discharge current assigned to it. As long
as there are no special instructions from the manu-
facturer, no more than the nominal capacity must be
taken. After discharge, also partial discharge, it must
be immediately charged.
2.2 Charging
All charging methods can be used with their limit
values according to DIN 41773-1 (IU characteristic
curve). Depending on the charging device design
and charging device characteristic curve, alternating
currents fl ow through the battery during the charging
process, which are superimposed onto the direct
current (< 0.1C(A) effective ripple). These superim-
posed alternating currents and the reactions of the
consumers lead to an additional warming of the
battery and strain on the electrodes with possible
resulting damage (see Point 2.5). Depending on the
system, charging can take place with the following
operating modes (according to VDE 0510-485-2).
(Batteries must not be charged upside down!)
a) Standby parallel and buffer operation
Here the consumers, the DC source and the battery
are continually switched on in parallel. Thereby, the
charging voltage is the operating voltage of the bat-
tery and at the same time the system voltage. For
standby parallel operation the DC source is capable
at all times of supplying the maximum consumer
current and battery charging current. The battery
only supplies current when the AC source fails. The
charging voltage to be set is 2.275V ± 1% (20 °C) x
the number of cells in series connection, measured
on the end poles of the battery. In buffer operation,
the DC source is not able to always supply the maxi-
mum consumer current at all times. The consumer
current intermittently exceeds the nominal current of
the DC source. During this time the battery supplies
current. It is not always charged at all times, how-
ever, the maintenance charge voltage of 2.275V/cell
at 20 °C x number of cells in series connection is
suffi cient to ensure a recharge. A consumer-and-
cell-number-dependent tuning should be done in
individual cases with the battery manufacturer.
b) Switching mode
The battery is disconnected from consumers during
charging. To shorten the recharging time, in the fi rst
charging step the battery is charged with a voltage
of 2.35–2.40V/cell up to a point in time when the
charging current drops to 0.07C(A)(t
1
). The charging
time of the fi rst phase is measured to reach this va-
lue. During the second phase of the recharging, a vol-
tage of 2.35–2.40V/cell is used, whereby the rechar-
ging time of the second phase should be 50% of the
fi rst phase (t
2
= 0.5t
1
). When exceeding t > t
1
+ 0.5t
1
the voltage is reduced to the maintenance voltage of
2.275V/cell (± 1%) at 20 °C.
c) Battery mode (charge/discharge mode)
The consumer is only fed from the battery. The char-
ging method is user-dependent and to be agreed
upon with the battery manufacturer.
2.3 Maintaining the full charge condition
(maintenance charging)
Devices with the specifi cations according to DIN 41773-1
must be used. They must be set so that the cell voltage
has an average of 2.275V ± 1%.
2.4 Supplementary and equalising charge
Before the fi rst commissioning, a supplementary
charge of the batteries must be carried out and
logged. Equalising charges are required after deep
discharge and insuffi cient charging. The battery
surface temperature must not exceed 45 °C during
this; if necessary, the charging must be interrupted
or switched to charge maintenance. The end of the
supplementary/equalising charge is reached when
the charge voltage and charge current no longer
show any change within two hours. Batteries, which
are installed retroactively in a battery network as a re-
placement, must be fully charged before installation.
2.5 Superimposed alternating current (AC)
During the recharging up to 2.4V/cell according to
the operating modes Point 2.2, the effective value of
the AC may be briefl y 0.1C(A). After recharging and
further charging (maintenance charging) in standby
parallel operation or buffer operation, the effective
value of the AC must not exceed 2A/100Ah nominal
capacity.
2.6 Charging currents
In standby parallel operation or buffer operation
without recharge step, the charging currents are not
restricted. The charging current should be 10A to 20A
per 100Ah nominal capacity (reference value). In cycle
operation, the charging current should not exceed
0.3C(A) (30A/100Ah).
