How to select UPS batteries and maintenance methods
The unstable quality of switching power supply often leads to the destruction, failure and loss of key raw materials in the hardware structure of computer equipment. Continuous power management system has gradually become a kind of standard weapon equipment which is not enough to obtain computer equipment. However, how to buy ups is often confused with users, and the key component of switching power supply is the battery, in order to choose a good ups, we need to choose a good, well-known brand battery. The following methods will teach you how to buy
1. Whether a specific battery
There are many kinds of sealed lead-acid batteries, and the importance and function characteristics of different types of batteries in production and production are not consistent; Stationary battery for wet charging products, it deprived of lithium battery life, long floating life, strong overcharging ability; Automotive starting batteries for instant products, focusing on dry charging high current starting and circulation system frequency role; Therefore, the ups management system focuses on whether the battery is specialized or not.
2. External query
Because there is no way to distinguish the quality of the battery from the application of a certain period of time, so before obtaining direct brand images only from the outside, the buyer needs to see whether the battery outer packaging box is robust and exquisite, whether the battery shell and the terminal of the connection is clean and bright, whether the seal is good, whether the terminal welding is firm, whether there is no leakage, deformation, crack, corrosion, etc., The quality of the battery is reflected from the outer surface.
3. Query the battery charging
The capacity of the battery can be measured according to the battery charging test. The newly purchased battery is charged continuously for 8 hours. The test is carried out under the inductive load, and the resistance value is inevitable.
4. Continuity issues
Under float charging conditions, the VRLA rechargeable battery is a negative absorption heat pump management system. Within 6 months after the first use, the float charging operating voltage will be unstable and gradually balance. After 6 months, the floating charge operating voltage difference of each rechargeable battery should not exceed 10 m V.
