Lead-acid batteries have taken a dominant position in the power system of forklifts due to their advantages such as mature technology, controllable cost and convenient maintenance. However, if the lead-acid battery of a forklift is not properly installed and debugged, it will not only reduce the battery's service life but also may cause safety accidents, affecting the production efficiency of the enterprise. Therefore, mastering the key points of installation and commissioning of lead-acid batteries for forklifts is of great significance for ensuring the stable operation of forklifts.

I. Preparations before Installation

(1) Inspection of equipment and tools

Before installing the lead-acid battery of the forklift, a comprehensive and detailed inspection of the relevant equipment and tools is required. First of all, confirm that the battery compartment structure of the forklift itself is intact, without deformation, damage or other conditions, to ensure that the battery can be installed smoothly. At the same time, check the fastening devices inside the battery compartment, such as bolts and clips, to ensure they are tight and undamaged, preventing the battery from shifting during the operation of the forklift.

For the tools required for installation, such as wrenches, screwdrivers, multimeters, etc., make sure they are functioning properly. The wrench should be of the appropriate specification to prevent slippage and damage when tightening or loosening the bolt. The multimeter needs to be calibrated to ensure the accuracy of the measurement data, so that parameters such as battery voltage and current can be precisely detected during the subsequent debugging process.

(2) Battery specification verification

Strictly check the specifications and models of lead-acid batteries to ensure they match the design requirements of the forklift. The parameters such as the voltage, capacity and size of the battery must comply with the technical standards of the forklift. Different models of forklifts have specific requirements for battery voltage. If the battery voltage does not match that of the forklift, it may cause the forklift to fail to start normally and even damage key components such as the motor. In addition, the size of the battery needs to be compatible with the battery compartment. If the battery is too large, it cannot be installed. If the battery is too small, it is prone to shaking during operation, which affects the battery's performance and service life.

At the same time, check the production date and quality certification documents of the battery to ensure that it is in good working condition. Avoid using expired or substandard batteries to guarantee the reliability of installation and commissioning work from the source.

(3) Personnel safety training

Personnel involved in the installation and commissioning of lead-acid batteries for forklifts must receive professional safety training. Lead-acid batteries may produce corrosive substances such as sulfuric acid during use and pose an electric shock risk. Therefore, staff need to understand the chemical properties of the batteries and safety operation procedures. The training content should include the correct wearing of protective equipment, such as acid and alkali resistant gloves, goggles, protective suits, etc. Master the emergency treatment methods for sulfuric acid leakage, such as neutralizing it with alkaline substances like lime; And understand the first aid measures for electric shock to ensure that timely and effective handling can be carried out in case of unexpected situations.

In addition, it is necessary to explain the operation norms and precautions during the installation and commissioning process to the staff, enhance their safety awareness and operational skills, and avoid safety accidents and installation mistakes caused by human factors.

Ⅱ. Key Steps in the Installation Process

(1) Battery handling and placement

Due to the relatively large weight of lead-acid batteries, appropriate tools and methods should be used during transportation to prevent the batteries from falling or being damaged by collisions. Generally, forklifts or dedicated battery handling vehicles can be used for transportation. During transportation, it is necessary to ensure that the batteries are stable and avoid violent shaking.

When placing the battery in the forklift battery compartment, pay attention to the positive and negative pole directions of the battery. Operate strictly in accordance with the installation manual to prevent the positive and negative poles from being connected in reverse. At the same time, it is necessary to ensure that the battery is closely attached to the bottom and the periphery of the battery compartment to avoid any gaps, so as to reduce the vibration of the battery during operation. For the situation where multiple batteries are connected in series, it is necessary to ensure that the connection positions between the batteries are accurate and error-free to prepare for the subsequent electrical connection.

(2) Electrical connection

Electrical connection is one of the key links in the installation of lead-acid batteries in forklifts, directly affecting whether the battery can supply power normally and the operational safety of the forklift. When connecting battery cables, it is necessary to ensure that the specifications of the cables match those of the battery and the forklift's electrical system. The cross-sectional area of the cables should meet the requirements of the battery's maximum discharge current to reduce line loss and heat generation.

When connecting, first clean the cable terminals and battery posts to remove the oxide layer and dirt on the surface to ensure good electrical contact. Then, use an appropriate wrench to firmly tighten the cable terminals onto the battery posts, ensuring a tight connection without any loosening. When connecting multiple batteries in series, they should be connected in the correct order one by one to ensure that the current can smoothly pass through the entire battery pack.

After the connection is completed, the electrical connection parts need to be inspected. Use a multimeter to measure the total voltage of the battery pack and confirm that the voltage value meets the design requirements. At the same time, check whether there are any abnormal conditions such as overheating or discoloration at the cable connection points. If any problems are found, they should be dealt with promptly.

(3) Fixation and Protection

After the battery is installed in place and the electrical connection is completed, it needs to be fixed to prevent displacement during the operation of the forklift. Use the fixing devices inside the battery compartment, such as bolts and clips, to firmly secure the battery inside. When tightening the bolts, follow the principle of diagonal tightening to ensure that the battery is evenly stressed and avoid damaging the battery casing due to excessive local stress.

In addition, protective treatment for the battery is also required. Install insulating protective sleeves on the battery terminals to prevent the terminals from coming into contact with external metal objects and causing short circuits. Organize and fix the battery cables to prevent them from rubbing against other components of the forklift, which could cause damage to the insulation layer. Meanwhile, insulating pads are laid in the battery compartment to further enhance the electrical insulation performance and ensure the safety of the operators.

Ⅲ. Key Tasks during the Commissioning Stage

(1) Voltage and capacity detection

After the installation of the lead-acid battery for the forklift is completed, the voltage and capacity of the battery should be tested first. Use a multimeter to measure the no-load voltage of the battery pack, and compare the measured value with the nominal voltage of the battery. The error should be within the allowable range. If the voltage value is too low, it may be due to insufficient battery power or internal faults in the battery, and further inspection is required.

For the detection of battery capacity, the method of discharge testing can be adopted. The battery is discharged through a dedicated battery discharge device at the specified discharge current and time, and the discharge curve and final voltage of the battery are recorded. Based on the discharge test results, evaluate whether the actual capacity of the battery meets the design requirements. If the battery capacity is insufficient, it may be necessary to charge or activate the battery to restore its performance.

(2) Charging and discharging performance test

Charging and discharging performance is one of the important indicators for measuring the quality of lead-acid batteries. During the commissioning stage, the battery needs to undergo charge and discharge tests to verify its charge and discharge efficiency as well as cycle life.

During the charging test, use a charger that meets the battery specification requirements and charge the battery according to the correct charging parameters. During the charging process, it is necessary to closely monitor the changes in battery voltage, current and temperature to ensure the safety and stability of the charging process. When the battery reaches a fully charged state, check whether the battery voltage has reached the saturation value and whether the charging current has dropped to the normal range.

The discharge test is conducted after the charging is completed, simulating the actual working load of the forklift to discharge the battery. During the discharge process, the voltage, current and temperature of the battery should also be monitored, and the discharge time and capacity of the battery should be recorded. Through charge and discharge tests, the performance status of the battery can be comprehensively understood, potential problems can be identified and dealt with in a timely manner.

(3) Matching and debugging with the forklift system

After the installation and commissioning of the lead-acid battery for the forklift are completed, it needs to be matched and debugged with the electrical system, control system, etc. of the forklift to ensure that the battery can provide stable and reliable power for the forklift. Start the forklift and check whether all the functions of the vehicle are normal, such as driving, lifting, turning, etc. Observe whether the parameters such as the battery level display and voltage indication on the dashboard are accurate. If there are any abnormalities, the connection lines between the battery and the forklift system as well as the control system need to be inspected and adjusted.

Meanwhile, test the operational performance of the forklift under different working conditions, such as full load, climbing slopes, and acceleration, to evaluate whether the power supply capacity of the battery meets the working requirements of the forklift. During the debugging process, the parameters of the battery should be fine-tuned according to the actual situation to optimize the matching degree between the battery and the forklift system, and improve the working efficiency and energy utilization rate of the forklift.

Ⅳ. Common Problems and Solutions
