How to buy lead-acid UPS batteries?

How to choose a lead-acid UPS battery 1. Whether it is a dedicated battery for UPS. There are many types of sealed lead-acid batteries. Different types of batteries have different processing points and performance characteristics; the fixed battery equipped with UPS is a wet-charged product. It requires low self-discharge, long floating charge life, and strong overcharge resistance. The starter battery for automobiles is a ready-to-use product, which focuses on the performance of dry-charged high-current start-up and cycle times; therefore, choose UPS system When using lead-acid batteries, first pay attention to whether it is a UPS dedicated battery. 2. Judging the quality of the battery. The open circuit voltage of lead-acid batteries has a great relationship with the proportion of internal acid. For batteries of different series and the same capacity, the higher the open circuit voltage, the higher the proportion of sulfuric acid after formation, and the less resistant to corrosion and battery life. Relatively short. 3. Charge and discharge detection Whether the capacity of the lead-acid battery reaches the nominal value can be tested by the charge-discharge test. After the newly purchased lead-acid battery has been continuously charged for more than 8 hours, the discharge test shall be carried out with a resistive load of a certain resistance. , When discharging, the terminal voltage of the battery should be measured every time according to the time. According to this, the ratio of the terminal voltage drop with time is drawn, and the battery with a slow voltage drop is preferred. 4. Observe the drop of open circuit voltage of the battery. If the situation permits, you can observe the change of the battery terminal voltage during the standing period of the lead-acid battery. The faster the drop, the worse the purity of the internal material and the faster the battery self-discharge. The worse the life span.
