Chapter Three Operation and Maintenance
1. Operation Conditions
Ambient temperature: AcmeG series optimum temperature is 15℃～25℃, the
higher and lower temperatures will impact battery performance
Operation temperature range
Ambient humidity：≤95％
Cabinet ventilation conditions: meet the standard EN 50272-2:2001
2. Capacity and Influencing Factors
2.1 The capacity of the battery is the capacity that battery can be discharged under
certain conditions, represented by the symbol ‘C’. The standard unit of measurement
for capacity is ampere-hour (Ah).
Capacity can be expressed in Rated Capacity or Actual Capacity. Please refer to
Table 1-1 for the Rated Capacity of Narada battery. The Actual Capacity is the
product of the discharge current and the discharge time i.e. Ah.
2.2 Factors that influence the Actual Capacity
Actual capacity is mainly related to the battery’s construction, manufacturing
process and operational environment. During operation, the factors that influence the
actual capacity are the discharge rate, end voltage, ambient temperature and discharge
time.
2.3 Discharge Rate
If the discharge rate (hour rate) is lower, the discharge current is larger, and the
discharge time is shorter, then the capacity that can be discharged will be lesser. For
example, the discharge current of 3 hours rate is larger than that of 10 hours rate; and
the capacity of 3 hours rate is smaller than that of 10 hours rate.
2.4 End Voltage
be able to discharge further. The end voltage of AcmeG series battery is typically
10.8V per block. Due to the characteristics of gel battery, the battery will not be able
to discharge even if the end voltage drops. The lower end voltage will harm the
battery, especially when the voltage drops to 0V and the battery cannot be recharged
The end voltage is the lowest working voltage below which the battery will not

in time. This will shorten the life of the battery.

3. Ambient Temperature, Capacity and Life
3.1 Relationship between Ambient Temperature and Capacity
VRLA batteries can be used in very low or high temperature (below -15ºC or
above 45ºC). However the battery data such as capacity life and floating voltage are
measured with temperature between 20ºC-25ºC as a standard. The capacity of the
battery will decrease with lower temperature as shown in Fig. 3-1 below.
As represented by the graph above, the capacity of the battery will decrease when
the temperature is too low. For example, if the temperature decreases from 25ºC to
0ºC, the capacity will be decrease to85% of the nominal capacity. The battery will be
in a less-charged state with lower temperature and this will lead to battery failure in
discharging and the active material in the negative plate to saltilize.

The capacity of the battery will increase when the temperature rises. For example,
the capacity will increase by 6% when the temperature increases by 10ºC. However
the high temperature will accelerate the corrosion of the grid and cause water loss in
the battery, thus shortening the battery life.
As such it is always important to control the ambient temperature at the customer
premises. Please ensure room ventilation and usage of air-condition is recommended
in high temperature working environment.
3.2 Floating Operation
Floating voltage is chosen with the assumption of battery operating under the
optimal working condition. If the floating voltage is too high, the battery floating
current will get larger and increase the grid eroding speed, thus reducing the service
life of the battery. When the floating voltage is too low, the battery will not be able to
maintain its fully-charged condition. This will create sulphate and reduces the battery
capacity, hence affecting the service life of the battery. The floating voltage of Narada
AcmeG series battery is 13.5V/block under 25ºC . The temperature compensation is at
-18mV/ºC /block.
Floating voltage under different temperature is calculated by the following
formula:
VT=13.5-(T-25)×0.003×6
VT—Floating voltage under T temperature
Table 3-2 Floating Voltage under Different Temperature
Note: If ambient temperature below 5℃ or above 40℃, temperature compensate is
no longer go on.

3.3 Equalization Charge
VRLA battery needs Equalization Charge regularly to ensure the battery
operating under 25ºC working condition. The equalization voltage of Narada AcmeG
series battery is 14.4V/block. The temperature compensation is at -30mV/ºC /block.
Equalization voltage under different temperature is calculated by the following
formula:
VT=14.4-(T-25)×0.005×6
VT—equalization voltage under T temperature
Table 3-3 Equalization Voltage under Different Temperature
Note: If ambient temperature below 5℃ or above 40℃, temperature compensate is
no longer go on.
3.4 Ambient Temperature and Life
High temperature is harmful to the battery and affects its service life. When the
ambient temperature exceeds 25ºC，the service life reduces by half for every 10ºC
increment in temperature. For example, the battery service life is 10 years under 25ºC
but if the operating temperature is 35ºC, the service life will become 5 years. The
formula to calculate the service life is as follows:
t25＝tT×2
（T－25）
/10
whereby T : actual ambient temperature
t
design life under T
T :

As such the ambient temperature should always be controlled.

4. Charging Request
4.1 Equalization Charging
Equalization charging should be carried out in the following situation:
a. There are more than two batteries which voltage is under 13.0V in one group.
b. More than three months after floating operation.
Equalization charging is recommended as follows:
Charge the battery group with constant current not exceeding 0.1C10A till the
average voltage increases to 14.1V/block(25ºC)，then change into constant
voltage of 14.1V/block charging. The equalization charging time should be 24
hours.
4.2 Battery Charging
Battery Charging should be carried out in the following situation:
a. The batteries should be recharged in time after discharge.
b. After battery system is installed.
c. Battery storage period exceeding three months or open circuit voltage lower
than 12.6V/block.
Battery charging is recommended as follows:
The batteries should first be charged on the constant current of 0.10C10A till the
average voltage of the batteries increases to 14.1V, then the batteries should be
charged with constant voltage of 14.1V till the charging has completed.
On some occasions, the batteries have to be fully charged immediately, then fast
charging could be adopted. The value of limit current should not be larger than
0.2C10A, and the charge voltage should be 14.1V/block(25ºC).
We can determine if the batteries are fully charged by one of following two
conditions:
a. After charging 18～24hours. The charging time will be lesser if it is not deep
discharged. For example at 20% DOD (refer to Table 2-1 for the Depth of
Discharge vs Charging Time), the charging time can be shorten to 10 hours.
b. Under the condition of constant voltage, the value of charge current has no
variation for continuously three hours.
5. Storage
All gel batteries experience self-discharge in open circuit. The result is that the
voltage of open circuit is decreased, and the capacity also decreases. Please note the

following during storage period:
5.1 The self-discharge rate is related to the ambient temperature. The degree of
self-discharge is smaller when the ambient temperature is lower, otherwise it will
be larger. The required temperature for Narada batteries’ storage is 5ºC to 30ºC.
The storage place must be clean, ventilated and dry.
5.2 An important parameter in storage is open circuit voltage, which is related to the
density of the electrolyte. In order to avoid permanent damage to the plate caused
by self-discharge, the batteries should be recharged as storage period shown in
following table. The equalization charge method should be adopted.
5.3 During storage, if the open circuit voltage is lower than 12.6V/block, the batteries
should be recharged before usage. The equalization charge method should be
adopted.
5.4 All batteries should be fully charged before storage. It is recommended to record
the storage time in the periodic maintenance record and to note down the time
when the next necessary recharge should be carried out.

Chapter Four Maintenance
1. Regulated Maintenance
1.1 Instruments and tools:
1.1.1 Digital Voltage Meter.
1.1.2 Insulated wrench.
1.1.3 Internal resistance, conductive and instant loading experiment instruments.
1.2 Monthly Maintenance
— Keep the battery-room clean.
— Measure and record the ambient temperature of the battery-room.
— Check each battery’s cleanliness, check damage and trace of overheating on
the terminal, container and lid.
— Measure and record the total voltage and floating current of the battery
system.
1.3 Quarterly Maintenance
— Repeat monthly inspection.
— Measure and record floating voltage of every on-line battery. If there is more
than one battery with voltage of less than 13.1V after temperature adjustment,
the batteries have to go through equalization charged. If the problem persists
after adopting the above-mentioned measure, the batteries will require yearly
maintenance or even three years’ maintenance. If all methods are ineffective,
please contact the manufacturer.
1.4 Yearly Maintenance
— Repeat quarterly maintenance and inspection.
— Check whether the connectors are loose or not annually.
— Perform a discharge test to check the exact load every year and discharge
30-40% of the rated capacity.
1.5 Three-year Maintenance
— Perform a capacity test every three years and every year after six years’ of
operation. If the capacity of the battery decreases to lower than 80% of the
rated capacity, the battery should be replaced.
2. Precautions
2.1 Insufficient Charge

E.&O.E.
If the floating voltage is not set correctly i.e. too low or not amend according to
the temperature, the battery system will have an insufficient charge state for a
long period of time. When the electricity is cut, the battery may not be able to
work because the active material is saltilized and the capacity is decreased.
2.2 Over Charge
Please ensure the rectifier transfers floating charge to equalization charge. If the
rectifier is not able to transfer charge modes, the battery system will always be in
an equalization charge state which may cause battery water loss, decrease in
service life, overheating and deformation.
2.3 Extreme Temperature
Maintain the correct temperature to ensure the performance of the battery.
Extremities in temperature will be detrimental to the battery life and performance.
2.4 Low End Voltage
The end voltage is an important parameter for battery. The normal end voltage is
10.5V and in some cases 9.6V. The battery will stop discharging when it reaches a
certain voltage. If the end voltage is too low, it will be difficult to recharge the
battery and decrease the charging efficiency, thus affecting the battery life.
2.5 Charging Battery Immediately after Discharge
If the battery is left uncharged for a long period of time i.e. > 2 hours after
discharging, it will affect the capacity and battery life. This is due to large size
PbSO4 being created in the negative and will be difficult to transfer to active Pb.
