Sunbattery SB6-1,2 User manual
Sealed lead batteries consist of cells that do not need
to be lled up with water for their entire working lives.
Pressure relief valves function as plugs, and any at-
tempt to open them will cause damage.
1. Before Service
Before being brought into service, all banks should
be checked: for mechanical damage; that the pola-
rity is correct; and that the connectors are rmly at-
tached. The following torque settings apply to screw
connectors.
2. Operation
Refer to EN IEC 62485-2 for operating and installa-
tion guidelines for these batteries. The battery should
be installed to avoid temperature shifts of > 3K.
2.1 Discharge
Do not discharge the battery below its cutoff voltage
for its designated discharge current. Unless the ma-
nufacturer species otherwise, do not draw more than
the nominal capacity. After discharge – even partial
discharge – the battery must be charged immediately
(it may be necessary to lift the pole covers). Before
charging the battery, make sure the charger is turned
off, polarity is correct (positive pole connected to the
positive connector) and separate loads are connec-
ted to a direct current power source. Turn the charger
on and begin charge as follows in point 2.2.
2.2 Charging
All charging procedures where the maximum and
minimum values correspond to DIN 41773-1 (IU
Kennlinie) may be used. Depending on the make of
the charger used and its charging curve, alternating
currents superposed to the direct current may ow
through the battery (< 0.1 C(A) ripple factor). The su-
perposed alternating currents and the contrary action
of loads can cause the battery to heat up abnormal-
ly and put additional strain on the electrodes – and
cause possible damage (see point 2.5). Depending
on the battery set-up, the following charging methods
can be used (corresponding to VDE 0510-485-2).
Batteries are not allowed to be charged upside down!
a) Continuous parallel supply and buffer supply.
In this case, the loads, direct current source and
battery are continuously connected in parallel. At the
same time the charging voltage is equal to the batte-
ry’s operating voltage and installation voltage. In con-
tinuous supply, the direct current source can always
supply the maximum load current plus the battery
charging current. The battery only supplies electricity
if the direct current source fails. The correct charging
voltage is 2.275 V ± 0.005 V (25°C) x the number of
cells connected in series, measured at the battery’s
terminal posts. In the case of buffer charging, the di-
rect current source is not able to supply the total load
current at any time. There are times when the load
current exceeds the nominal current of the direct cur-
rent source. During these times, the battery supplies
power. It is not always fully-charged, though the oat
voltage of 2.275 V/cell (25°C) x the number of cells
is sufcient to ensure recharge in a series connec-
tion. A load-and-cell-quantity-dependent calibration
should be provided, in any specic instance, by the
manufacturer.
b) On-off operation
Whilst being charged, the battery is disconnected
from its load. To decrease recharging time, the batte-
ry can be charged at 2.35-2.40 V during its rst char-
ging phase before the charging current is reduced
to 0.07 C(A) (t1). The rst charging phase lasts until
this value is reached. In the second charging phase,
a voltage of 2.355-2.40 V/cell is used. The charging
duration of this phase should be 50% of the rst
(t2=0.5T1). If the value of t > t1 + 0.5t1 is exceeded,
the charging voltage is reduced to 2.275 V/cell
(± 0.005 V) at 25°C.
c) Battery operation (charging / discharging cycle)
The load is only charged from the battery. The correct
charging procedure depends on the user and should
be claried with the manufacturer.
2.3 Maintaining full charge (oat charging)
Appliances tting the criteria set out in DIN 41773-1
should be used. They should be set up so that the
average cell voltage is 2.275 V ± 0.005 V.
2.4 Top-up or equalisation charging
To prolong battery life, it is advisable to do a top-up
charge before running the batteries, providing the
batteries have been stored for more than 6 months –
but not longer than 9 months – with reference to the
date of manufacture. The batteries should also have
a terminal voltage of less than 2.1 V/cell. The top-up
charge should be carried out using the values speci-
ed. For batteries retrotted to form a replacement
battery bank for standard oat charging, no equalisa-
tion charging is needed to bring the terminal voltage
in line with the other batteries.
2.5 Superposed alternating currents
In the case of the operating scenarios outlined in
point 2.2, the effective value of the alternating current
can temporarily rise to 0.1 C(A) whilst being rechar-
ged at up to 2.4 V/cell. After recharging and ongoing
charging (oat charging) in a continuous battery pow-
er supply or oat battery supply, the effective value of
the alternating current should not exceed a nominal
capacity of 2 A / 100 AH.
2.6 Charging currents
In continuous battery supplies and oat battery sup-
plies, there is no charging current limit if there is no
recharging stage. The charging current should be 10
to 20 A for every 100 AH of nominal capacity (Bench-
mark).
2.7 Temperature
The recommended operating temperature range for
lead batteries is 10°C to 30°C. The ideal temperature
range is 20°C ±5 (according to EUROBAT). Higher

temperatures decrease battery life. The technical
specications apply to a nominal temperature of
25°C. Lower temperatures decrease available capa-
city. Exceeding the maximum allowable temperature
from 50°C is prohibited. Persistent operating tempe-
ratures above 40°C should be avoided.
2.8 Temperature-based oat charging voltage
and rapid discharge
The oat charging voltage of 2.275 V/cell ± 0.005 V/
cell applies to a temperature of 25°C. A temperatu-
re-based recalibration of the oat charging voltage is
required to avoid over-charging at higher temperatu-
res and under-charging at lower temperatures. The
recommended recalibration factor is -3 mV/cell/V°C
in a oat charging situation. To avoid a “thermal ru-
naway”, for temperatures above 40°C the oat char-
ging voltage must be recalibrated to the temperature.
A power-charging procedure can then be used if a
rapid recharge is needed. In this case, the charging
current should not exceed 0.01 C(A) and constantly
decreases until it’s below 0.01 C(A). Once a level of
±0.1 V/cell has been reached, it should be switched
to oat voltage charging.
2.9 Electrolyte
The electrolyte is diluted sulphuric acid suspended
in mats.
3. Battery care and inspection
The battery must always be kept in a clean and dry
condition to avoid leakage currents.
The battery should be cleaned according to the ZVEI
information leaet “Cleaning of Batteries”. The batte-
ry’s plastic parts should only be cleaned using water
without additives; using organic cleaning products is
not recommended. The following should be checked
and recorded at least every 6 months:
- Battery voltage
- Voltage of some individual cells/battery blocks
- Surface temperature of some cells
- Battery room temperature
If the cell voltage differs from the average oat char-
ging voltage by ±0.1 V/cell, or if the surface tempe-
rature of different cells/blocks differ from each other
by more than 5 K, please contact customer services.
The following must be measured and recorded yearly:
- Voltage of all cells/battery blocks
- Surface temperature of all cells
- Battery room temperature
- Leakage resistance according to EN 60896-21
Annual visual inspection:
- Screw connections. Unxed screw connections
should be checked that they are rmly attached.
- The battery rack / storage area
- Ventilation (both aeration and extraction) according
to EN IEC 62485-2
4. Inspections
Inspections should be carried out according to EN
60896-21. Please also refer to additional guidelines
e.g. EN 50172 and VDE 0100-710. Refer to the afo-
rementioned EN. In order to ensure a reliable power
supply, the whole battery should be replaced once its
expected service life – given its operating conditions
and temperature – has expired.
5. Problems
If you identify errors with the battery or the charging
set-up, contact customer services without delay. The
measurement specications in point 3 enable easier
fault-checking and troubleshooting. A maintenance
contract helps with the timely identication of problems.
6. Storage and decommissioning
If cells/batteries are put in storage or taken out of
service for a signicant amount of time, they should
be kept in a dry, frost-free room. To avoid damage,
maintenance charging should be carried out as spe-
cied in point 2.4.
7. Transport
Sun batteries are not hazardous materials as long as
they are secured against short circuits, slipping, falling
over and damage (Hazardous Material Act, GGVS, vo-
lume No. 2801a). This applies to transport by road, rail,
sea and air, and to IATA rules (Rule A67), ADR (Rule
598), IMDG (Rule 238.2), and UN 2800 special provisi-
ons. The transported goods should not carry any dan-
gerous traces of acid. All sealed lead batteries and cells
whose containers are no longer leak-proof or damaged
are subject to the corresponding special provisions.
