According to the different operation requirements and working conditions of forklifts, the appropriate battery capacity and voltage can be flexibly selected to meet the power demands of forklifts.

(4) High power output capacity

1. ** Instantaneous High Current discharge ** : When a forklift starts, accelerates, or moves heavy objects, the battery needs to be able to provide an instantaneous high current to meet the high power demands of the motor. Lead-acid batteries have excellent high-rate discharge performance, capable of releasing a large amount of electrical energy in a short period of time, providing strong power for forklifts, enabling them to start quickly and complete handling operations smoothly. For instance, in logistics warehouses, forklifts need to frequently load and unload goods. The high power output capacity of lead-acid batteries can ensure that forklifts complete the handling and stacking of goods in a short time, thereby enhancing work efficiency.

2. ** Stable power output ** : Throughout the entire operation of the forklift, the lead-acid battery can maintain a relatively stable power output, ensuring that the forklift's operational performance does not experience significant fluctuations. Even when the battery power gradually decreases, lead-acid batteries can still maintain a certain output power, enabling the forklift to continue completing its operation tasks and avoiding the impact on the normal use of the forklift due to a rapid decline in battery power.

2. Application Scenarios of Lead-Acid Batteries in Forklifts
