What kinds of batteries are commonly used for UPS power supplies?

What are the commonly used batteries for UPS power supplies? There are three types of UPS batteries: open-type liquid lead-acid batteries, maintenance-free batteries and nickel-chromium batteries. Currently, batteries supplied by UPS manufacturers are generally maintenance-free. The following is a brief introduction to the advantages and disadvantages of the three batteries: 1. Open lead-acid batteries: Advantages: less investment, longer life than maintenance-free batteries, and lower temperature requirements. Disadvantages: chaotic maintenance, special battery room, corrosive gas emission, on-site charging for 50-90 hours, special maintenance. 2. Battery without maintenance: Advantages: No need to add liquid and other maintenance, can be transported in full condition without special maintenance. Disadvantages: Failure to recycle and recharge in time will cause harm to the battery, the temperature is more active, the life is shorter, and it is more expensive than lead-acid batteries. 3. Ni-Cr batteries: Advantages: low maintenance requirements, long life, low temperature, no harmful gas emissions. Disadvantages: The most expensive of the three. Which is better to use lithium battery or lead-acid battery for UPS power supply? According to the figure. JPG lithium battery is a super new star, with its safety, light weight, long life, complete charge and discharge, low maintenance cost, no recall effect and other characteristics sensitively occupy the market, and gradually replace the traditional lead-acid battery. At present, most data centers and communication base stations use lead-acid batteries, but more because there is no better choice. With the opening of UPS battery technology, the improvement of lithium battery technology, the gradual improvement of cost performance, and the smaller and smaller standards, the planning of data centers will also have a vivid impact. The use of lithium batteries perfectly prevents the various effects of lead-acid batteries. The advantages of high energy density, small size, light weight, long life, and temperature planning make it dumped in the market. The IDC power supply system adopts the lithium battery UPS power supply system supplied by Emerson. Using lithium batteries, there is no risk of battery failure, and the failure of a single battery will not cause the entire UPS power supply battery to fail to operate. With the continuous development of lithium battery technology, the advantages of using lithium batteries as UPS backup power sources have become more and more obvious, and lithium battery manufacturing methods have been adopted by more and more companies. We can see that lithium batteries are gradually becoming an indispensable new friend in the data center computer room.
