Therefore, it is of great significance for enterprises to correctly select lead-acid batteries and adopt scientific methods to extend their lifespan.

In the field of industrial production, forklifts, as important handling equipment, cannot operate efficiently without stable power support, and lead-acid batteries are the core power source for many forklifts. The performance and lifespan of lead-acid batteries directly affect the working efficiency and usage cost of forklifts. Therefore, it is of great significance for enterprises to correctly select lead-acid batteries and adopt scientific methods to extend their lifespan.
1. Key Points for Correctly Choosing Lead-Acid Batteries
(1) Match capacity requirements
The working intensity and duration of forklifts vary, and so do their demands for battery capacity. If the battery capacity is too small to meet the daily working requirements of the forklift, frequent charging will increase the burden on the battery and shorten its service life. However, if the capacity is too large, it will not only increase the procurement cost, but also may not match the installation space of the forklift due to the large volume and weight of the battery, affecting the normal operation of the forklift. Therefore, when making a choice, it is necessary to calculate the appropriate capacity range based on factors such as the power of the forklift, working time and operation frequency, and select a lead-acid battery within this range.
(2) Pay attention to brand and quality
High-quality brand lead-acid batteries have stricter quality control and more advanced production techniques during the manufacturing process, which can ensure the stable performance of the batteries. The material of the plates and the purity of the electrolyte of this type of battery are more guaranteed, with high charging and discharging efficiency and a long cycle service life. On the contrary, some low-quality batteries produced by small workshops, although inexpensive, are prone to problems such as incomplete charging, rapid discharge, and leakage. These not only affect the normal operation of forklifts but also pose potential safety hazards. Therefore, it is very necessary to choose brand products with good reputation and high market recognition.
(3) Check the appearance and parameters
When making a purchase, carefully inspect the appearance of the battery to see if there is any damage, bulging, leakage or other conditions. At the same time, it is necessary to verify all the parameters of the battery, such as rated voltage, rated capacity, production date, etc., to ensure that the parameters match the requirements of the forklift. The production date should not be too long. Even if lead-acid batteries are not in use, they will still have self-discharge. Storing them for too long will affect their performance.
2. Methods for Extending the Lifespan of Lead-acid Batteries in Forklifts
(1) Standardize charging operations
Charging is a key link that affects the lifespan of lead-acid batteries. Use the original or matching charger to avoid overcharging or undercharging the battery due to inconsistent charger parameters. When charging, ensure good ventilation in the environment and keep it away from fire sources and heat sources. When the battery power is charged to about 90%, the charging time can be appropriately reduced to avoid overcharging. In addition, do not charge the battery only when it is completely drained. It is recommended to charge it in time when there is 20% to 30% of the battery left.
(2) Use discharge reasonably
When using a forklift, it is necessary to avoid deep discharge of the battery. Deep discharge can cause excessive corrosion of the battery plates, shortening their service life. Try to stop using the forklift before the battery level drops to 20% and charge it in time. At the same time, it is necessary to avoid forklifts working for long periods under high-intensity conditions such as heavy loads and climbing slopes, and reduce the occurrence of large current discharges to lower battery wear and tear.
(3) Do a good job in daily maintenance
Daily maintenance is indispensable for extending the lifespan of the battery. Regularly check whether the connection wires of the battery are firm. If any are loose, tighten them in time to prevent poor contact from causing poor battery discharge or insufficient charging. To keep the battery surface clean and dry, avoid the adhesion of dust, oil stains and other impurities, and prevent short circuits of the battery. For maintainable lead-acid batteries, it is necessary to regularly check the electrolyte level. When the level drops below the minimum mark, distilled water should be replenished in time. Be careful not to add tap water or electrolyte to avoid affecting the battery performance.
3. Frequently Asked Questions and Answers
(1) Does the lead-acid battery of a forklift need to have its electrolyte replaced regularly?
Under normal circumstances, the electrolyte of lead-acid batteries in forklifts does not need to be replaced regularly. The main function of the electrolyte is to participate in the chemical reactions of the battery. As long as distilled water is replenished in time during daily maintenance to keep the electrolyte level normal, the concentration of the electrolyte can be maintained within an appropriate range. If the electrolyte is frequently replaced, it will instead disrupt the chemical balance inside the battery, affecting its performance and lifespan. Only when the electrolyte is severely contaminated or deteriorates and other special circumstances occur, does it need to be replaced, and the replacement must be carried out by professionals.
(2) What are the special precautions for the use of lead-acid batteries in forklifts in winter and summer?
When used in winter, due to the lower temperature, the capacity of lead-acid batteries will decrease and their discharge capacity will also weaken. Therefore, it is necessary to pay attention to maintaining the working environment temperature of the battery and avoid storing it for a long time at too low a temperature or using a forklift. When charging, you can appropriately extend the charging time, but do not overcharge. In summer, when the temperature is relatively high, batteries are prone to overcharging and the evaporation rate of the electrolyte accelerates. It is necessary to strengthen the inspection of batteries, replenish distilled water in a timely manner, and avoid charging and using forklifts in high-temperature environments to prevent problems such as battery bulging and leakage.
In conclusion, by making the right choice of lead-acid batteries, managing charging and discharging well and maintaining them on a daily basis during use, and paying attention to the usage characteristics of different seasons, their lifespan can be effectively extended, providing a reliable guarantee for the efficient operation of forklifts and reducing the operating costs of enterprises.
