Storage
The batteries are pre - charged before leaving the factory. Please note the following points before installation:
1. Stored batteries can generate flammable gases. Therefore, keep the batteries well - ventilated and away from sparks and open flames.
2. After opening the package, check the quantity and appearance of the accessories. Upon arrival, check whether the battery packaging (carton) is damaged. Then carefully open the carton without damaging the battery.
3. Open the battery packaging near the battery installation site. Hold the bottom of the battery and take it out. Do not lift it by the terminals. Note! If you apply force on the terminals to move the battery, the sealant may crack.
4. After opening the package, check the quantity and appearance of the accessories.
Manintenance
1. After verifying no abnormality in the battery,install t on the prescribed location(e.g.cubicle of battery stand)
2. If the battery is to be accommodatedin a cubicle,place it at the lowest place of the cubicle whenever it is practicable.Keep at least 15mm distance between the batteries.
3. Alwaysavoid installing the battery close to aheat source(such asa transformer).
4. Since a storage battery may generate ignitable gases,avoid installing close to an item that produces sparks(suchasswitchfuses)
5. Before making connections,polish the battery terminals to brightmetal.
6.When amultiplenumber of the batteries are used,first connectthe inter-battery ina correctmanner,and
then connect the battery to thecharger or the load.
In this case, the positive terminal of the battery should be connected to the positive terminal of the charger or load, and the negative terminal to the negative terminal.
If the battery is incorrectly connected to the charger, the charger may be damaged. Be sure to avoid incorrect connections. Each connection nut and bolt must be tightened with the torque as shown in the following table:

M5 |
2.0~4.0N*m(20~40kgf*cm) |
|
M6 |
4.5~8.0N*m(45~80kgf*cm) |
|
M8 |
11~13N*m(110~130kgf*cm) |
Check batteries regularly and make notes
* In order to prevent battery damage, check the battery regularly and make records in the following ways
| Time | Content | Method | Check standards | Handling of exceptions |
| Monthly check | Total voltage in float charge | Measure the total voltage with a voltmeter | Float charging voltage * number of batteries | Adjust to float charging voltage * battery number |
| Half-yearly inspections | Total voltage in float charge | Measure the total voltage with an electric voltmeter with an accuracy of 0.5 or more | The total voltage is (float charging voltage * number of batteries) | If the voltage value is high, adjust the voltage |
| Single cell battery voltage during float | Measure the total voltage with an electric voltmeter with an accuracy of 0.5 or more | Within the 2.25+0.1v/ grid | Ask us to correct errors, any battery that exceeds the allowable value should be repaired and replaced | |
| surface | Check the electric tank and upper cover for damage or acid leakage | No damage or acid leakage from replacement of electric tank or top cover | If so, replace it | |
| Check whether the battery is contaminated by dust | The battery is free from dust pollution | If the pollution is cleaned with a wet cloth | ||
| Check the battery rack, cable connecting plate, connection cable , and terminal for rust | The battery rack, connection plate, and connection cable terminal are free from rust | Find the cause and proceed Cleaning, rust removal and repair |
|
Annual inspection (in addition to the semi-annual inspection items, the following items should also be added) |
||
|
adapting piece |
Tighten the nuts and bolts |
Check (connect the screw and the bolt torque) |
