[0002] UPS lead-acid battery is a device used to store electrical energy in UPS system. It is composed of several batteries connected in series and is widely used in many fields. When the mains power is normal, the lead-acid battery converts electrical energy into chemical energy and stores it internally. When the mains power is interrupted, the UPS system will convert the chemical energy in the battery into electrical energy through the inverter to supply the load and ensure the continuous operation of the equipment. Therefore, lead-acid batteries for different application scenarios have different design concepts to meet different discharge performance and warranty requirements. For UPS backup power supply, small UPS power supply generally has a warranty of 1 to 2 years, and medium and large UPS has a warranty of 3 to 5 years. The matching lead-acid batteries need to meet the same warranty period.
[0003] However, when the city power is cut off, the UPS needs to be able to provide 5 to 15 minutes, or even longer equipment working time. Therefore, the battery needs to be able to provide the power required by the equipment, and must be a high-rate discharge time. However, the lead-acid battery required for high-rate discharge generally increases the manufacturing cost in the design. The high-power discharge will also increase the internal resistance of the battery. Therefore, when the equipment is discharged with a large current, the battery energy consumption will increase, thereby reducing the performance of the lead-acid battery and shortening the service life of the lead-acid battery.

The battery module 2 is provided to provide power to the device, and the capacity of the used battery module 2 is increased, so that the internal resistance of the lead-acid battery can be reduced during discharge, thereby enhancing the discharge power of the lead-acid battery, and at the same time not only improving the high-rate discharge performance of the lead-acid battery, but also extending the service life of the lead-acid battery.
[0027] The positive plate 21 and the negative plate 22 are configured to be thin sheets, the thickness of the positive plate 21 is between 2.0 mm and 2.3 mm, the thickness of the negative plate 22 is between 1.4 mm and 1.6 mm, the width of the positive plate 21 and the negative plate 22 is set to 39 mm, and the width of the separator 23 is set to 48 mm. Improving the number, thickness and width of the positive plate 21 and the negative plate 22 can increase the capacity of the lead-acid battery, thereby enabling the lead-acid battery to reduce internal resistance during discharge and enhance the discharge power of the lead-acid battery.
