To avoid overloading the electric cables and
contacts as well as the inadmissible generation
of gases, only connect the battery to a charger
rated and approved for the battery's capacity.
EPzV batteries have a low charging gases emis-
sion. In the gassing stage the current limits given
in EN 62485-3 must not be exceeded. If you
purchased your charger separately, you are
advised to have the manufac turer's aftersales
service verify its suitability.
Properly extract all gases generated when
charging the battery. Open or remove the lids or
covers from battery trays or compartments.
Ensure proper ventilation pursuant to EN 62485-
3. Check that the charger is off and connect the
battery leads to the correct poles (plus to plus
and minus to minus). Do not turn on the charger
until after that.
While charging, the temperature inside the bat-
tery will rise by about 10 K. Before starting a
charging cycle, you should therefore allow the
temperature to drop to less than 35 °C. To
ensure proper charging results, check that the
temperature is 15 °C or higher before you start
charging. Provide appropriate means of con-
stant charger voltage control if the temperatures
are permanently higher than 40 °C or lower than
15 °C.
The applicable correction factor is -0.004 V/Z
per Kelvin (K). The reference temperature is
30 °C.
Note on operating batteries in danger zones:
These batteries are exposed to explosive atmos-
pheres and belong to equipment category Ex I or
Ex II pursuant to EN 60079. Check the warning
signs affixed to the battery.
2.3 Equalizing charge
Applying an equalizing charge is meant to main-
tain the battery's service life and capacity. Such
charge should be applied after a normal charg-
ing cycle and must be applied after a total dis-
charge and if recharging is repeatedly found to
be insufficient. Equalizing charges must be
applied by means of the chargers approved by
the battery manufacturer only.
Check the temperature.
2.4 Temperature
A battery temperature of 30 °C is called the
nominal temperature. Higher temperatures will
shorten the battery's life, lower temperatures will
reduce its capacity. Operating the battery at its
temperature limit of 45 °C is not allowed.
2.5 Electrolyte
Sulfuric acid fixed in gel serves as the electro-
lyte. Thus, electrolyte density cannot be meas-
ured.
3.
Maintenance
Do not water the battery.
3.1 Daily
Recharge the battery after every time of use.
3.2 Weekly
Inspect the battery for dirt and mechanical dam-
age. Clean the battery, as necessary. Have
qualified persons immediately repair any dam-
age you find.
3.3 Quarterly
Fully recharge the battery, allow not less than 5
hours of downtime, the measure and keep a
record of the following parameters:
• Total voltage
• Individual voltages
Contact Aftersales Service for immediate verifi-
cation/repair if you discover major differences
from previous measurements or differences
between the cells.
3.4 Annually
DIN EN 1175-1 demands that a skilled electri-
cian the vehicle's and the battery's insulation
resistance as necessary but at least once a year.
Measure the battery's insulation resistance in
conformity with DIN EN 1987-1. Pursuant to DIN
EN 62485-3, the insulation resistance reading
should not be lower than 50 Ω per volt of nomi-
nal voltage. Thus, the minimum resistance is
1000 Ω for batteries up to a nominal voltage of
20 V.
4.
Care
To prevent the occurrence of leak currents, keep
the battery dry and clean at all times. ZVEI's
Code of Practice No. 6 "Battery Cleaning"
describes how to clean batteries. Visit the ZVEI
web site for a free download. Drain and duly
discharge of the liquid in the battery tray. If you
find the tray insulation to be damaged, clean and
repair the damaged spots to ensure insulations
to DIN EN 62485-3 and to avoid tray corrosion.
You are advised to contact the Aftersales Ser-
vice in case cells need to be removed.
5.
Storage
Fully recharge a battery prior to any extended
downtime period and keep the battery in a dry
and frost-proof room. The following recharge
cycles will ensure that the battery remains ready
for use:
1.
Fully recharge every three months as
described in section 2.2. Fortnightly
recharging may be necessary if consumers
such as measuring or control equipment is
connected.
2.
Trickle charging at a charging voltage of
2.30 V x number of cells.
Consider the time of storage when assessing the
battery's service life.
6.
Problems
Immediately contact the Aftersales Service if you
discover any battery or charger problems. Read-
ings taken as described in section 3.3 will help
you locate a problem and troubleshoot the bat-
tery. A Service Level Agreement with GNB will
support the early detection of problems and
extend the life of the battery.
7.
Transport and installation of individual
cells
Transport and install individual cells in upright
position (pole connectors facing upward). Do not
transport, install or operate cells that are lying on
their side as this will provoke an irreversible loss
of capacity and early battery failure.
