In contrast, the maintenance of lithium batteries requires more professional techniques and equipment, and the maintenance cost is relatively high.

(2) Performance advantages

Stable power output: Lead-acid batteries can provide stable voltage and current during the operation of forklifts, ensuring smooth power output for the forklifts. Whether the forklift is climbing a slope fully loaded with goods or performing rapid cargo loading and unloading operations, lead-acid batteries can continuously provide sufficient power for the forklift, ensuring its working efficiency and stability. This stable power output characteristic enables the forklift to operate reliably in various complex logistics and warehousing operation environments.

Excellent low-temperature performance: In some logistics and warehousing sites in cold regions, the ambient temperature is relatively low, which poses a severe test to the performance of batteries. Lead-acid batteries can still maintain good performance in low-temperature environments. Although their capacity will decline, compared with some other battery types, the decline is relatively small. This enables forklifts equipped with lead-acid batteries to operate normally in low-temperature environments, meeting the demands of logistics and warehousing operations.

(3) Safety advantages

Mature technology, safe and reliable: Lead-acid batteries have a development history of over a hundred years, and their production and manufacturing technologies as well as application technologies are all very mature. After long-term practical tests, lead-acid batteries have a relatively high level of safety under normal use and maintenance. For instance, its internal structure is reasonably designed, which can effectively prevent electrolyte leakage and avoid safety accidents caused by electrolyte leakage.

Less likely to cause serious accidents such as fire and explosion: Compared with other batteries like lithium batteries, lead-acid batteries are less likely to cause serious safety accidents such as fire and explosion during use. Due to their chemical properties, lithium batteries may trigger intense chemical reactions when subjected to abnormal conditions such as overcharging, overdischarging, and short circuits, leading to fires and explosions. The chemical properties of lead-acid batteries are relatively stable. Under normal usage conditions, the probability of such serious accidents occurring is relatively low, providing a safer guarantee for logistics and warehousing operations.

3. Challenges Faced by Forklift Lead-Acid Batteries in the Logistics and Warehousing Industry

(1) Low energy density

The energy density of lead-acid batteries is relatively low, which means that they can store less electrical energy under the same weight or volume. Therefore, when forklifts are equipped with lead-acid batteries, their driving range is often limited. For some high-intensity and long-term logistics and warehousing operations, the endurance capacity is obviously insufficient.

(2) Long charging time

The charging time of lead-acid batteries is relatively long, usually taking 8 to 10 hours to fully charge the battery. This is a significant issue in the logistics and warehousing industry, as forklifts cannot operate during charging periods, which can lead to operational disruptions. Especially during peak business hours, forklifts are frequently used. If the charging time is too long, it will seriously affect the overall operational efficiency of logistics and warehousing. To alleviate this problem, enterprises often need to be equipped with multiple sets of batteries so that when one set of batteries is being charged, another set can continue to power the forklift, but this will increase the cost input of the enterprise.

(3) Environmental protection pressure

The issue of used battery disposal: Lead-acid batteries contain harmful substances such as lead and sulfuric acid. If used batteries are not properly disposed of, they will cause serious pollution to the environment such as soil and water sources. With the rapid development of the logistics and warehousing industry, the usage of lead-acid batteries in forklifts is constantly increasing, and the generation of used batteries is also increasing accordingly. At present, although China has established a relatively complete recycling system for used lead-acid batteries, there are still some non-standard behaviors in the actual recycling process. Some used batteries flow into illegal channels and have not been properly handled.

Pollution during the production process: The production process of lead-acid batteries also generates certain environmental pollution, such as the discharge of pollutants like waste gas, waste water, and waste residue. Although in recent years, lead-acid battery manufacturers have continuously increased their investment in environmental protection and improved their production processes to reduce pollutant emissions during production, the pressure of environmental protection still exists.
