When choosing a lead-acid battery, forklift users need to fully consider the tonnage of the forklift and the actual operating conditions in order to select the most suitable battery, maximize the efficiency of the forklift and reduce operating costs.

In the operation system of forklift, lead-acid battery is the core power source, and its performance is directly related to the operation efficiency and service life of forklift. With the continuous expansion of forklift application scenarios, different tonnage forklifts have put forward differentiated demands for lead-acid batteries, and a series of innovative battery products have emerged, bringing a new choice for forklift users.

## Light tonnage forklift: small and efficient lead-acid battery

Light tonnage forklifts (usually 1-3 tons) are mainly active in warehouses, supermarkets and other relatively compact places, characterized by frequent start and stop, short distance handling. This type of forklift requires higher space occupancy and charging and discharging efficiency of lead-acid batteries. A new type of thin plate and high specific energy lead-acid battery is an ideal choice. The thin plate design increases the number and surface area of the plate, so that the battery has more active substances in a limited space, and improves the charge and discharge performance of the battery. At the same time, the use of advanced lead paste formula and tight assembly process, effectively improve the specific energy of the battery, so that the battery can still output strong power under the small volume, to meet the light tonnage forklift truck frequent start and stop of the instantaneous large current discharge, and significantly shorten the charging time, reduce the standby time of the forklift truck, significantly improve the working efficiency.

## Medium tonnage forklift: balanced durable lead-acid battery

The application scenarios of 3-8 tons of medium tonnage forklifts are more extensive, such as logistics transfer centers, manufacturing workshops, etc., which undertake the handling and loading and unloading tasks of medium weight goods, and the operation intensity is larger. For such forklifts, long life, high capacity and balanced performance of lead-acid batteries are the key. Some manufacturers have introduced lead-acid batteries with special alloy grid frames, which have excellent corrosion resistance and can effectively resist the corrosion caused by the battery charging and discharging process and extend the battery life. In terms of capacity, by optimizing the electrolyte formula and plate structure, the battery capacity is increased to ensure that the forklift can maintain stable power output under long-term, high-intensity operation. In addition, this type of battery also pays attention to the stability of the charge and discharge process, can adapt to the current changes under different working conditions, and provide reliable power support for medium tonnage forklift trucks.

## Heavy tonnage forklift: strong and durable lead-acid battery

Heavy tonnage forklifts of more than 8 tons are often used in ports, large construction sites, etc., which need to handle super-heavy goods, and the working environment is complex and the power requirements are extremely high. The lead-acid battery suitable for heavy-tonnage forklift truck needs to have super high current discharge capacity and long endurance. Lead-acid batteries with large capacity and high rate discharge have become the mainstream choice. With thicker plates and higher active material content, these batteries can release huge currents in an instant to meet the powerful power needs of heavy-tonnage forklifts when starting and moving heavy loads. At the same time, by improving the structural design and sealing technology of the battery, the loss of the electrolyte is reduced, the energy conversion efficiency of the battery is improved, the driving range is extended, and the forklift is ensured to operate steadily for a long time in harsh operating environments, reducing the charging frequency and improving the overall operating efficiency.

In the face of the diverse needs of forklifts with different tonnage, new lead-acid batteries continue to innovate and break through in design, technology and performance, providing a more accurate and efficient power solution for the forklift industry. When choosing a lead-acid battery, forklift users need to fully consider the tonnage of the forklift and the actual operating conditions in order to select the most suitable battery, maximize the efficiency of the forklift and reduce operating costs.
