button cell battery cr2025

　　How to install UPS batteries and how to manage them?

　　1. Installation of button cell battery cr2025

　　1. Design the connection plan in advance. It is recommended to remove the metal accessories on hand during installation.

　　2. Before the button cell battery cr2025 is put on the shelf, physical inspection must be carried out and the open circuit voltage must be measured to avoid rework. When one end of the cable is connected to the button cell battery cr2025, the other end should be insulated or held in the palm of your hand to prevent misplacement and sparking.

　　3. After one end of the wiring is connected, the other end should tap the pole to be connected when connecting to effectively avoid the impact of incorrect connections.

　　4. When two people are connected at the same time, there should be no connection or potential relationship between the corresponding button cell battery cr2025 packs. Because the two people have the same potential, if there is a potential difference between the batteries connected to each other, the battery and the two people will form a circuit, and an electric shock accident may occur.

　　5. After the PS battery pack is connected in series, the voltage between the total positive and total negative of the button cell battery cr2025 pack is relatively high. When connecting to the MCCB (battery switch), each wire should be connected to the MCCB first and then to the corresponding battery terminal. ; Or leave a breakpoint in the battery pack, and then connect the breakpoint after completing the connection between MCCB and button cell battery cr2025 pack. For multiple groups of battery packs connected in parallel, each group should have a broken end, and after connecting the MCCB terminal, use a multimeter to check the polarity and then connect the broken ends.

　　2. Management of UPS batteries

　　1. Charging for the first time. For brand-new batteries, everyone generally thinks that the overall performance is relatively good, so during the management process, they often feel that they do not pay attention to it. For the battery pack of UPS power supply, the initial charging needs to ensure that the charging time is more than 12 hours. If it is not used frequently, it must be charged before placing it. Otherwise, it will affect the function of the battery and affect the UPS. The power supply causes some damage.

　　2. Avoid excessive discharge. The life of the battery also has a certain relationship with the number of discharges, because during the use of the UPS, many staff have a certain degree of over-discharge due to lack of experience. During the discharge process of the UPS, it will also have a certain impact on the battery itself. Therefore, it is necessary to minimize the number of deep discharges. In addition, when the UPS power supply is supplying power to the battery pack, there will often be an alarm, and the alarm will last for 4-5 seconds. Based on the time and sound of this alarm, you can judge whether the power supply is normal or not, and thus whether the battery pack is in a deep discharge stage.

　　3. Maintain indoor temperature. The function of the battery is often closely related to the environment in which it is located, so the environment of the computer room will have a very direct effect on the performance of the UPS power supply. It can be seen from the corresponding requirements and regulations that the optimal temperature of UPS power supply is 25°C, the highest temperature should not exceed 40°C, and the lowest temperature should not be lower than 0°C. Generally speaking, the output capacity of the battery will often decrease due to the influence of temperature. In addition, when the temperature is too high, it will also have a certain impact on the inverter and stop running, thus causing a series of problems to the remote computer room equipment. negative effect.

　　4. Choose the appropriate charging method. At this stage, when charging UPS power supply, the constant voltage cutoff charging circuit is used by most charging systems, because the UPS itself is still a relatively sensitive system and has certain requirements for the charging voltage and current. When the charging voltage is too high or too low, it will have a certain impact on the battery pack. If the charging and discharging current value is too large, it will easily lead to deformation of the battery plates and a decrease in battery performance. Therefore, when performing actual charging, a suitable charger must be used, preferably with constant current and constant voltage functions, thereby maximizing the service life of the UPS power supply and further ensuring people's life safety. Reduce security threats.
