What are the detection and maintenance methods of Shante UPS power battery

Santak UPS power battery detection method: 1. Use a multimeter to measure the terminal voltage of the battery. Practice has proved that measuring the floating charge terminal voltage of the UPS power battery with a multimeter cannot determine whether the old battery has failed. Therefore, it is generally necessary to measure the terminal voltage of the battery offline or online. The terminal voltage of the tested battery is about 12V (for a 12V battery), and the minimum cannot be lower than 10.5V. A battery with less than 10.5V is an undervoltage or a failed battery. If this kind of battery still does not reach 12V after charging or activation charging, it is a failed battery. 2. Detect whether the UPS battery has the characteristic of outputting large current at the moment of startup. The switching time of the backup UPS power battery from the mains power supply to the inverter power supply is required to be less than 7ms, and the general design is about 4-5ms. This means that once the mains power supply is interrupted, the UPS battery must output the current required by the load in less than 4-5ms. Some failed batteries can meet the requirements of terminal voltage and capacity, but they cannot reach the requirements of large current in less than 4-5ms. They are also unqualified batteries. The characteristic of UPS battery's instantaneous output of high current can only be detected when the mains is closed. There is a certain risk if the battery performance is not known, and it is generally not carried out. 3. Judging the capacity of UPS battery The traditional method of judging the battery capacity of UPS power supply is the same as the method of judging the general battery. The whole battery pack is separated from the communication power system and connected to the resistance wire, discharged at a constant current rate of eight or ten hours, and then discharged at a maximum rate of eight or ten hours. The discharge time and current of a single battery that reaches the end-of-discharge voltage first can be used to estimate its capacity. Four maintenance methods for Santak UPS batteries: 1. Maintain a proper ambient temperature. Generally speaking, the major factor that affects UPS battery life is the ambient temperature. The excellent ambient temperature required by general battery processing manufacturers is between 20-25°C. 2. Regularly charge and discharge the float voltage and discharge voltage in the UPS power battery. Both have been adjusted to the rated value at the factory, and the discharge current is increased with the increase of the load. The load should be adjusted reasonably during use. , Such as controlling the number of electronic devices such as microcomputers. Under normal circumstances, the load should not exceed 60% of the UPS rated load. Within this range, the battery discharge current will not be over-discharged. 3. Utilize the communication function. At present, most large and medium-sized UPS batteries have operational performance such as communication with a microcomputer and program control. Install the corresponding software on the microcomputer, connect the UPS through the serial/parallel port, and run the program, you can use the microcomputer to communicate with the UPS. Generally, it has functions such as information query, parameter setting, on-time setting, automatic shutdown and alarm. 4. Replace the used/bad batteries in time. When one or some of the batteries in the battery pack are damaged, the maintenance personnel should inspect and detect each battery to remove the damaged battery. When replacing a new battery, you should try to buy the battery of the same manufacturer and the same model, and it is forbidden to mix the use of acid-proof batteries, sealed batteries, and batteries of different specifications. 5. Operating environment Sunte UPS power supply battery should be installed in a clean, cool, ventilated, and dry place as much as possible, and should not be affected by sunlight, heaters or other radiant heat sources. The battery should be placed upright and not inclined at an angle. The terminal connection between each battery should be firm.
