2.6 Charging currents
The charging currents are not limited to
2.4 V/ cell. When exceeding the charging
voltage of 2.4 V/cell greater water decompo-
sition occurs.
The charging currents per 100 Ah nominal
capacity shown in Table 1 may not be
exceeded.
2.7 Temperature
The recommended operating temperature for
lead-acid batteries is 10°C to 30°C. The tech-
nical data apply for the nominal temperature
20°C. The ideal operating temperature is
20°C +/_ 5 K. Higher temperatures shorten
the service life. Lower temperatures reduce
the available capacity. The maximum temper-
ature of 55°C may not be exceeded.
2.8 Temperature-related charge voltage
A temperature-related adjustment of the
charge voltage within the operating tempera-
ture of 10°C to 30°C is not necessary.
Should the temperature range be lower than
10°C and/or higher than 30°C a temperature
related adjustment of the charge voltage
should be made. The temperature correction
factor is (-0.004 V/C per K).
Should the temperature constantly rise above
40°C, then the factor is (0.003 V/C per K).
2.9 Electrolyte
The electrolyte is diluted sulphuric acid. The
nominal electrolyte density is based on 20°C
and the nominal electrolyte level when fully
charged maximum +/ _ 0.01 kg/l.
Higher temperatures reduce the electrolyte
density, lower temperatures increase the
electrolyte density. The associated correction
factor is 0.0007 kg/l per K.
Example: electrolyte density of 1.23 kg/l at
35°C corresponds to a density of 1.24 kg/l at
20°C or electrolyte density of 1.25 kg/l at 5°C
corresponds to a density of 1.24 kg/l at 20°C.
3. Battery maintenance and control
The electrolyte level must be checked regu-
larly. If it has dropped to the lowest elec-
trolyte level mark, purified water must be
added as under DIN 43530 Part 4, maximum
conducting capacity 30 _S/cm.To avoid leak-
age currents keep the battery
clean and dry. Cleaning the battery should
be carried out as specified in the ZVEI pam-
phlet on battery cleaning.
Plastic battery components, in particular the
vent caps, must only be cleaned with water
containing no additives. At least every 6
months the following must be measured and
recorded:
- battery voltage
- voltage of a few selected cells/monobloc
batteries
- electrolyte density of a few selected
monobloc batteries
- electrolyte temperature of a few selected
monobloc batteries
The following must be measured and record-
ed annually:
- voltage of all bloc batteries
-electrolyte density of all bloc batteries
- electrolyte temperature of a few selected
bloc batteries
Should the float charge voltage in one cell
deviate more than + 0.1 V or - 0.05 V from
the average value (see 2.3), customer serv-
ices must be called in.
Annual visual checks:
- on bolted connectors, check that unsecured
bolt connectors are firmly seated
- on battery installation or arrangement
- on ventilation.
4. Tests
Tests must be conducted according to DIN
43539 Part 1 and 4. In addition, special test
instructions such as under DIN VDE 0107
and DIN VDE 0108 must be observed. 5. Faults
Should faults be detected in the battery or
the
charging device, customer services should
be
called in immediately. Measurement data
under
Section 3 simplify fault detection and
removal.
A service contract with us facilitates the time-
ly detection of faults.
6. Storage and taking out of operation
Should cells/batteries be stored or taken out
of operation for a longer period of time they
mustbe placed, fully charged, in a dry, frost-
free room.
To avoid damage the following-charging
methods can be chosen:
1. Equalizing charges on a quarterly basis as
under Section 2.4. In average ambient tem-
peratures of more than 30°C monthly equal-
izing charges may be necessary.
2. Float charging as under Section 2.3.
7. Transport
Batteries which show no damage of any kind
are not treated as dangerous goods under
the road and railway transport regulations
(GGVS and GGVE) if they are secured
against short circuits, sliding, overturning or
damage and stacked and secured appropri-
ately on palettes
(GGV's margin No. 2801 a). The batteries
ready for dispatch must not show any exter-
nal dangerous traces of acid.
For all sealed batteries and cells whose ele-
ments are leaking or damaged the exception-
al regulation No. 69 applies.
8. Technical data
The nominal voltage, the number of blocks,
the nominal capacity (C10 = CN) and the
battery type are obtained from the type plate.
Other capacities (Cn) at different discharge
voltages (In) with the corresponding dis-
charge times (tn)can be obtained from the
OGi tables.
