How to choose an efficient and durable lead-acid battery has become the focus of many enterprises.

In modern logistics and industrial production, electric forklifts have become the main force of material handling with their advantages of environmental protection and low noise. As the core power source of electric forklift, the performance of lead-acid battery is directly related to the working efficiency and service life of forklift. How to choose an efficient and durable lead-acid battery has become the focus of many enterprises.

Identify forklift operation requirements

Different forklift operation scenarios have different requirements for battery performance. For example, in large logistics warehouses, forklifts need to carry heavy loads frequently and travel long distances, which requires high capacity and long battery life. Taking a common 2-ton electric forklift as an example, if its daily working hours exceed 8 hours, frequent cargo handling and long-distance transportation, then equipped with a capacity of 500Ah or more lead-acid battery is more appropriate, can ensure that the forklift in the entire work shift stable operation, reduce the frequency of charging, improve work efficiency. On the contrary, in the small factory floor, the forklift operation intensity is low, the driving distance is short, the smaller capacity battery can meet the demand, but also reduce the cost.

Pay attention to battery technical specifications

Capacity: Capacity is a key indicator to measure the performance of lead-acid batteries, and the unit is ampere hours (Ah). The larger the capacity, the more electricity stored, the longer the forklift lasts. For example, the 4PzS560 lead-acid battery dedicated to Linde A15 forklift adopts advanced lead-acid technology and has higher energy density, which can output more energy under the same volume, extend the use time of a single charge, reduce the number of charges, and improve the overall working efficiency.

Voltage: The common voltage of the electric forklift is 24V, 36V, 48V, etc., which needs to be adapted to the electric system such as the forklift motor. If the voltage does not match, the forklift performance will be affected, and even the equipment will be damaged. When selecting, make sure to refer to the voltage parameters specified in the forklift manual to ensure that the battery perfectly matches the electrical system of the forklift.

Discharge characteristics: high-quality lead-acid batteries should have stable discharge characteristics, and can maintain stable voltage output under high load. Like the 4PzS560 lead-acid battery, even if the forklift is in high intensity operation, the performance will not be affected by the battery voltage drop, ensuring the continuity and stability of the work, avoiding the pause in the process of cargo handling, and improving the efficiency of the operation.

Consider battery durability

Material quality: The material quality of key components such as battery plate and separator determines its durability. The plate is made of high quality lead calcium alloy, which is resistant to corrosion and aging and can extend the service life of the battery. The separator is made of materials with high microporosity and low resistance, which can effectively prevent short circuit of positive and negative electrodes and improve battery performance and life. For example, some high-end lead-acid batteries use imported high-quality diagonal partitions with high porosity and low resistance, which greatly improves battery durability.

Manufacturing process: Advanced manufacturing process can ensure the stability of the internal structure of the battery and reduce the occurrence of failures. If the hot melt welding technology is used to connect the plate, the contact resistance can be reduced, and the charging and discharging efficiency and reliability of the battery can be improved. The vacuum acid filling process is used to make the electrolyte distribution more uniform and improve the overall performance and consistency of the battery.

Cycle life: Cycle life refers to the number of charge and discharge cycles of the battery under certain conditions. The longer the cycle life, the lower the economic cost of the battery. Generally speaking, the cycle life of high-quality lead-acid batteries can reach 1500 times. In the selection, priority is given to products with long cycle life to reduce long-term use costs.

Pay attention to battery safety performance

Leakproof liquid design: In the use of lead-acid batteries, if leakage occurs, not only corrodes the equipment, but also has security risks. Therefore, it is necessary to choose a battery with a good leak-proof design, such as the use of sealed shells, special sealing rings, etc., to ensure that the battery has no risk of leakage during normal use and transportation.

Explosion-proof function: The battery will produce flammable gas such as hydrogen when charging and discharging, which has the risk of explosion. The battery with explosion-proof function is provided with an explosion-proof device in the shell design, which can effectively prevent explosion and ensure operation safety when the internal pressure is too high or there is an open flame. If some battery shells are made of explosion-proof materials, the top plug is equipped with a special valve structure, which can discharge excess gas in time to avoid danger.

Over-charge and over-discharge protection: Over-charge and over-discharge can seriously damage the battery life and even cause safety accidents. The battery with overcharge and overdischarge protection function can automatically cut off the circuit to protect the battery when the charging reaches a certain voltage or discharge to a certain degree. Some high-end batteries are also equipped with an intelligent battery management system (BMS), which monitors the battery status in real time to ensure safe and stable operation of the battery.

Evaluate brand and after-sales service

Brand reputation: Well-known brands usually invest heavily in product quality, technology research and development, production process, etc., and product performance and reliability are more guaranteed. Choosing a brand with good market reputation and high user evaluation can reduce the purchase risk. For example, some brands with many years of production experience and reputation in the industry, the lead-acid batteries produced by them have undergone strict quality testing, stable performance, and are trusted by users.

After-sales service: High-quality after-sales service can solve the problems encountered by users and reduce maintenance costs. Choose a supplier that provides responsive, professional repair services to ensure that batteries can be repaired quickly when they fail. The supplier should also provide value-added services such as battery maintenance training and regular inspection to help users properly use and maintain the battery and extend its service life.

The selection of efficient and durable lead-acid batteries for electric forklifts requires comprehensive consideration of forklift operation requirements, battery technical parameters, durability, safety performance, brand and after-sales service. Only in this way can we choose the right "heart" for the electric forklift truck, improve operation efficiency, reduce operating costs, and help the efficient development of enterprises.
