6 Use of battery
6.1 Supplementary charge
During the delivery and storage, the battery will lose part of the capacity due to self discharge, so
please supplement charge before use;
If storage occurs before installation / connection, supplement charge regularly;
Supplementary charge according table 2 below before use:
Table 2 the time interval of supplementary charge and storage temperature
Storage
temperature
Time interval of
supplementing
charge
Supplementing charge way
200C or less Every 9 months a) Charging at a constant voltage of 2.23-
2.30V/cell and initial current to be less than 0.3C (A) for 2-3
days
b) Charging at a constant current of 0.3C(A) and a constant
voltage of 2.30-2.40V/cell for 10-16 hours
c) Charging at a constant of 0.1C(A) for 8-10 hours
Three options for choice
200C ~300C Every 6 months
300C ~400C Every 3 months
Note:
Current value C is rated capacity of battery.
Example: rated capacity of 2V300AH battery is 300AH, 0.1C (A) = 0.1X300 = 30A;
6.2 Discharge

6.3 Capacity discharging test
Examples.
6.3.1 Off-system test method
a) Settle the battery group for 1 hour from the system after full charge, adopt the test load connect
method and proceed the discharge test at 10hours discharging rate under the ambient
temperature 25±50C .
b) Terminal voltage, ambient temperature, and start time should all be checked and recorded before
commencing discharge.
c) Terminal voltage, discharge current, room temperature should be checked and recorded
throughout the discharge period. Testing interval is 1 hour; discharge current shall not exceed
1% of the stipulated data. Reduce the time intervals to every 5mins as the test nears completion,
Or approaches end point voltages.
d) Discharge current multiplied by discharge time gives the capacity taken from the battery. When
battery discharge at 10hour discharging rate, if the temperature is not 250C, then it should be
calculated according to the below formula on the base of the capacity obtained in the test.
Ce = Cr/﹛1+K (t-250C )﹜
t-refers to the temperature;
K-refers to the temperature coefficient (K = 0.006/0C when discharging at 10H discharging rate,
K = 0.008/0C when discharge rate is 3H. K = 0.01/0C when discharge rate is 1H.)
e) Battery should be recharged by 1.1-1.3 times of the initial new specification
after finishing discharge.
6.3.2 On-system test method
a) In the direct current power system, adjust the out-put voltage of the inverter to protection voltage
(e.g.46V), battery supply the power to the load, then identify and test the battery with the lowest
voltage, and worst capacity.
b) Open the inverter and charge the battery, then wait 1hour after full charge.
c) Precede test at 10hour discharge rate on the worst battery identified in a). Terminal voltage,
temperature, discharge time, and room temperature should be tested and recorded before and
after the test and every hour. Notes should be taken at the moment the final voltage is showing to
record the discharge time accurately.
d) Discharge current * discharge time = capacity of the battery group. If the room temperature is not
250C, the capacity should be calculated according to the formula in (A).
JUBILEE STORE L.L.C

Page - 15 - of 23
e) After finishing the test, re-charge the battery to recover its capacity.
f) Draw the discharge curve according to the test data.
6.3.3 Check-aimed discharge test method
In order to control the estimated capacity of the battery group at any time, it is necessary to carry out the
check-aimed discharge test.
a) In DC power supply system, adjust the output voltage of the rectifier to protection voltage (for
example 46V), and the battery supply electricity to communication load. Terminal voltage,
temperature, room temperature and discharge time of the single battery should be tested and
recorded before and after the battery discharge. Until 30-40% of the rated capacity is released.
b) Re-charge the battery after finish discharge, the charged value should be 1.2times that of the
discharged value.
c) Draw discharge curve according to the notes, and keep record for comparing with future test.
Remark:
1) Off-system test method is not recommended for UPS system battery group.
2) When operating the on-system test method and check-aimed capacity test, if the tested UPS
equipment equipped with discharge performance itself, the test performance of discharging
should be opened. If it is without discharge test performance, its AC input should be
disconnected before proceeding with discharge test.
Note:
1) The above mentioned capacity test are the most frequently used in daily maintenance, but
whatever method is used, it is very important to keep a feed to the system during the test
period. Therefore, before processing the test, we should investigate whether there is plan to
stop electricity and the standby generator should be ready to work at any time.
2) Apply multi meter, inner-resistant instrument, conductance instrument to make a definitive
test before the capacity discharge test.
3) In order to make sure that accuracy of the capacity test, professional on-system test
instrument and test load should be adopted.
6.3.4 Judgment on lagged battery
Terminal voltage of the laggard battery is lower, so it should be tested under the discharging condition. If
the terminal voltages are lower on the average during the three continuing discharging cycle test, it can
be judged as the laggard battery of the group. Equalizing charge should be applied when laggard battery
is identified

battery appearance and battery life; pay more attention to charging voltage.
The used charger should have digressive automatic constant voltage device, please contact us if
use other kind of charger.
If the ambient temperature is not 250C , temperature compensation should be applied on the voltage,
using the formula is U=U250C - K×(T -25)
T—ambient temperature; K—temperature compensation coefficient
Judgment on charge end point, usually, if the battery charge can meet any one of the below listed
condition, it can be regarded as the charge end point.
a) Charged value is not less than 1.2 times of the released value.
b) The current is less than 0.005C10A (C10 = rated capacity of the battery) during the final
period of charging.
c) The current is steady for 5 hours during the final period of charging.
