Although energy storage lead-acid batteries and power lead-acid batteries both belong to the lead-acid battery system, they have significant differences in design concepts, performance focuses, and application scenarios, and together they constitute an important branch of lead-acid batteries in the fields of energy storage and power output.

Energy storage lead-acid batteries take deep cycle life and stability as the core design goals. The plates are made of thick plates and high-tin alloy technology. The proportion of active materials pays attention to uniformity and adhesion strength, and can withstand more than 3,000 deep charge and discharge cycles. The density of its electrolyte is controlled at a relatively low level of 1.21-1.24g/cm³. By optimizing the separator structure, the acid stratification phenomenon is reduced to ensure long-term reliable operation in scenarios such as off-grid energy storage and backup power supply. Typical applications include solar photovoltaic energy storage systems, backup power supplies for communication base stations, and grid energy storage projects for peak shaving and valley filling. The capacity of individual cells is usually in the range of 200-1000Ah, and 2V individual cells are used to form battery packs to meet high-voltage requirements.

Power lead-acid batteries focus on instantaneous power output and starting performance. They adopt a thin plate and multi-plate structure design. Conductive materials such as graphite are added to the positive plates to increase the reaction speed, and expansion agents are introduced to the negative plates to inhibit the crystallization of lead sulfate. Its plate grid adopts a radial or chain design to reduce internal resistance, capable of releasing a large current of 2-5 times in a short time. It is suitable for scenarios such as starting electric vehicles and driving low-speed electric vehicles. The voltage of individual battery cells is mostly 12V, and their capacity is concentrated in the range of 30 to 200Ah. Different power demands are met through series and parallel combinations. To adapt to the vibrating environment, the battery casing adopts a reinforced rib structure and the terminal post sealing process enhances the anti-vibration performance.

There are also differences in maintenance requirements between the two types of batteries: energy storage batteries need regular equalization charging to eliminate voltage deviations of individual cells, while power batteries pay more attention to the control of discharge depth to avoid sulfation of the plates due to excessive discharge. Although lithium-ion batteries have replaced lead-acid batteries in some fields, lead-acid batteries still hold an important market share in energy storage and low-speed power sectors due to their mature recycling system, low cost advantage and wide temperature adaptability. With the continuous improvement of lead-acid battery technology, such as the application of colloidal electrolyte and carbon additives, its performance has been constantly enhanced and its application scenarios have been further expanded.
