1. Connection and Disconnection Sequence When Charging the Electric Forklift Battery:

a. First, unplug the battery socket of the forklift.
b. Connect the battery port (the socket of the movable end on the vehicle) to the charger.
c. Finally, connect the AC power supply of the charger to the utility power supply of either AC380V or AC220V. Turn on the charging switch. When the working light is on, the charging starts. When the battery is fully charged, the "fully charged indicator light" will turn on to indicate that the charging is complete.

Note: Pulling out the charging plug during the charging process will generate an arc. The plug can only be pulled out after turning off the charger. After charging, a large amount of hydrogen will accumulate around the battery. Any open flame is not allowed. The cover plate on the battery should be opened during the charging process.

2. The battery should try to avoid overcharging and over-discharging as much as possible. When the voltage of a single battery drops to 1.70V, it should be charged in a timely manner. When the fuel gauge shows 70% or below, it is over-discharging. Frequent over-discharging will affect the capacity of the battery. When the battery is close to the over-discharging limit value, the forklift control system will automatically activate the protection function. First, the operation of the forklift lifting motor will be restricted, while the traveling motor can still continue to work. At this time, the forklift should be driven to the charging area for recharging.

3. The battery should be charged in a timely manner after each use, and the time interval should not exceed 24 hours.

4. The battery should be charged in a cool, ventilated environment away from open flames to avoid hydrogen explosion.

5. Prevent the battery from being stored in a discharged state, as storing a discharged battery is harmful to the battery. For batteries that are not used for a long time, they must be charged once a month (using the normal charging method).

6. The surface of the battery, the connecting wires, and the bolts should always be kept clean and dry.

7. The battery connections must be kept in good contact to avoid sparks that may burn out the terminal posts or cause the battery to explode.

8. No harmful impurities should fall into the battery. The instruments and tools used to measure the density, temperature, and liquid level of the electrolyte should all be kept clean.

9. No conductive objects should be placed on the battery cover to prevent the battery from short-circuiting.

I. Daily Inspection

1. Liquid Level: If the liquid level is lower than the rated level, it will shorten the service life of the battery. Moreover, too little electrolyte will cause the battery to overheat and be damaged. Therefore, it is necessary to always pay attention to whether the electrolyte is sufficient.

2. Terminal Posts, Wires, and Covers: It is necessary to regularly check the corrosion caused by oxidation at the joints of the battery terminal posts and the connections with the wires. At the same time, check whether the cover is deformed and whether there is any overheating phenomenon.

3. Appearance: A dirty battery surface will cause leakage. The battery surface should always be kept clean and dry.

II. Regular Maintenance

Check the liquid level (by opening the battery cover) and specific gravity of the battery electrolyte every half month or at the end of each month. If the liquid level cannot be seen, distilled water should be added in a timely manner until the liquid level can be seen (do not use tap water, mineral water, or electrolyte). When the specific gravity deviates from the specified value, it should be adjusted.
