| | Operation Environment and Safety | Keep batteries away from any source of ignition, organic solvent, or direct sunlight [More] | Operating Temperature Range:
Max. Range: -40℃～+70℃ (See specific battery specifications)
Optimal Range: 25±5℃
Relative humidity ≦ 95%
Altitude ≦ 4000m
Keep batteries away from any source of ignition, organic solvent, or direct sunlight;
Keep the consistent ambient temperature; the temperature difference between each batteryof the same battery bank ≦3℃.
[Retract] | | Installation Cautions | Match batteries into battery banks, and group the batteries of the same or similar open-circuit voltage as a bank. The voltage difference of a single cell is recommended to be a grade. [More] | ☆ Match batteries into battery banks, and group the batteries of the same or similar open-circuit voltage as abank. The voltage difference of a single cell is recommended to be a grade.
☆ Check and make sure batteries are normal, then install batteries at the predetermined location (eg a batteryrack).
☆ Do not install batteries near any heat sources (eg a transformer).
☆ Because batteries may produce flammable gas during storage, keep away from any devices with possibilityof sparks (eg a fuss) during installing.
☆ Before connection, clean battery terminals and make them shine with metallic luster.
☆ Be careful not to short-circuit battery positive and negative terminals with conductive materials.
☆ In multiple use, make sure batteries are connected correctly and then connect batteries to the chargeor load. The positive terminals should be connected with the positive of the charger or load,while negative with negative. If batteries are not connected to the charger correctly, the charge will bedamaged. Make sure there is no connection error.
☆ Connect wires tightly and make sure every connection nut and bolt is screwed down. But do not overexertto prevent damages to terminals. The recommended tightening torque is as follows.
[Retract] | | Transportation and Storage | As batteries are relatively heavy, you must pay attention to the selection of the means of transportation. No rolling or throwing is allowed.[More] | ☆ As batteries are relatively heavy, you must pay attention to the selection of the means of transportation. No rolling or throwing is allowed;
☆ When carrying batteries, do not touch the terminal and safety valve;
☆ Batteries are already charged when delivered out of the factory. Therefore, you must prevent battery short circuit during transportation;
☆ Before batteries are installed, you can store them with the temperature of 0~35℃, but for no more than 6 months. Batteries that have been stored for more than 6 months must be equalizing-charged. The storage place must be clean, airy and dry;
☆ If you need to store batteries that have been used, make sure that you fully charge them before storage and then store them according to requirements.
[Retract] | | Battery Maintenance | Keep the battery appearances and operating environment clean and dry.[More] | Cleaning
☆ Keep the battery appearances and operating environment clean and dry.
☆ Do not cause static when cleaning batteries.
☆ Clean batteries with a wet cloth. It's prohibited to use gasoline, alcohol or any other organic solvents to clean batteries.
Cautions
☆ Every month, recommend inspection every battery voltage.
☆ Every three months, recommend equalization charge for one time.
☆ Effect of temperature on float charge voltage: -3mV/℃/Cell.
☆ Length of service life will be directly affected by the number of discharge cycles, depth of discharge, ambient temperature and charging voltage.

Monthly Inspection[More] | Inspection and Maintenance
1） Monthly Inspection | Item | Content | Benchmark | Maintenance | ① The total float
charge voltage
of the battery
bank | Inspect the voltage of the battery bank's
positive and negative
terminals with a
voltmeter | The float charge
voltage of a single
cell x battery
quantity | Adjust the deviation value
to the benchmark value | ② Battery
appearance | Inspect the battery case,
lid to check wether there
is leakage, blow-up, or damage | The appearance is normal | Please check the reason of
the unusual appearance;
and if it affects the normal
use, replace the battery | Inspect whether there is
dust or dirt | The appearance is
clean | Clean the dust and dirt with a
wet cloth | Inspect whether the
connection cables
and terminals get rusty | No rust | If there is rust, please clean
the rust, replace the rusty
connection cables, and apply rust inhibitor | ③ Connection
parts | Inspect whether bolts
and nuts get loose | Firm connection (see
the torque table) | Tighten the loose bolts and
nuts according to the
requested torque | Clean the battery
bank’s connection bars
and terminals | No corrosion | For slight corrosion,
disassemble the connection
bar and immerse it in water for
cleaning; for serious corrosion,
change the connection bar and after cleaning the connecting
points with a steel brush
reconnect and tighten the new one | ④ Safety Valve | Shake the safety valve
gently to check whether
it is fastened securely | Firmly, no loose | If the safety valve is loose,
fasten it | Check whether the
safety valve is
working: apply the
foaming liquid around
the safety valve to
observe its gas | Bubbles appear
periodically | It is abnormal if the safety
valve is in longtime closing or
opening and need to change
the safety valve (and check
the battery water loss
condition at the same time ) | ⑤ Switch | Cut off the AC power, and
switch to the UPS, power
cabinet or DC power | The AC power supply
switches to the
power cabinet or DC
power smoothly | Correct the possible deviation | | 2） Quarterly Inspection

please contact us | | | 3） Yearly Inspection | Item | Content | Benchmark | Maintenance | Verification
discharge
testing | Cut off the AC power and
discharge with load;
discharge 30%~40% of
