How long is the UPS battery life, UPS battery replacement method. Nowadays, our UPS batteries are more and more use, and the UPS battery has always been the top priority of our instrumentation, and the battery is directly related to whether our equipment can be used normally. So how long is our battery life? What is the replacement method of the UPS battery? The UPS battery life length UPS service life depends on the environment, maintenance and maintenance of the operation, the company's attitude towards the old UPS, if it is inefficient, the capacity is not enough, the operation is poor, if the temperature is too high, the gray layer is too large, moist, etc.

Differentize the life of the UPS battery, maintenance and maintenance is not in place, and will shorten the life of UPS. UPS power supply - free battery, its life is generally 3-5 years. Some users will use long life models, such as 8 to 10 years, longest more than 20 years.

The normal life of the UPS is still relatively long. It can be used in 5-8 years, and the capacity will be significantly dropped in a reasonable use of electric maintenance every month. The capacity will be significantly dropped.

Affecting the important factors and precautions for UPS power storage battery life 1, the ambient temperature is too high, which will cause the battery to overcharge the gas, the ambient temperature is too low, the battery will be insufficient, which will affect the battery life. Therefore, it is generally required that the ambient temperature is about 25 ° C, and the UPS battery floating voltage value is also set according to this temperature. In actual application, the battery is typically charged in the range of 5 ° C to 35 ° C, which is less than 5 ° C or higher than 35 ° C, which greatly reduces the capacity of the battery, shortening the battery life.

2, the deeper the battery discharge depth, the less the number of cycles, so the depth discharge should be prevented during use. Although the Shart UPS power supply has battery low potential protection, the UPS will automatically shut down when the unit battery is discharged to about 10.5V.

However, if the UPS is in a light discharge or no-load discharge, the depth discharge of the battery is also caused. The so-called discharge depth refers to the percentage of the capacity of the battery in the battery group to use the battery pack discharge. 3.

Before installed, the battery's residual capacity should be determined according to the battery's open circuit voltage, and then supplement the battery to supplement the battery. Snant battery on the standby shelves, a supplementary charge should be performed every 3 months. It can be determined by measuring the battery open circuit.

Take 12V battery as an example. If the open circuit voltage is higher than 12.5V, it indicates that the battery energy is more than 80%.

If the open circuit voltage is below 12.5V, supplement charging should be performed immediately. If the open circuit voltage is less than 12V, it means that the battery storage electrical can be less than 20%, the battery is unable.

4, for example, 100AH ​​battery, c = 100A. Lead acid freely maintaining the best charging current of the battery is about 0.1c, the charging current cannot be greater than 0.

3c. The charging current is too large or too small to affect the battery life. The discharge current is generally required between 0.

05c to 3c, and the UPS can meet this requirement in normal use, but it should also prevent accidental conditions, such as battery short circuit, etc. 5. Since the UPS battery is a standby mode of operation, the main situation is in the normal conditions of the market, only when power is powered off.

In order to extend the service life of the battery, the UPS charger is generally controlled by constant voltage limit. After the battery is full, it is converted to a floating state, and each floating voltage is set to around 13.6V.

If the charging voltage is too high, the battery will be overcharge, and it will make the battery insufficient charging. 6, the valve controlled lead-acid battery due to the adoption of the absorbent electrolyte system, there is no gas during normal use, but if the user is improper, the battery is overcharge, the gas will occur, and the battery internal pressure is Will increase, open the pressure valve on the battery, severely burst the battery. So the UPS power supply with quality is critical.

Shante high quality strict workmanship production UPS power supply is worthy of your trust. 7, the UPS is in the operation, pay attention to monitor the end voltage value of the battery pack, the floating current value, the voltage value of each battery, the battery pack and the DC bus, and the insulation state. 8.

Do not add or reduce the load of several monomer batteries in the battery pack, which will result in uniformity of unbalanced cell capacity and charging, reduce battery life. 9, the battery should be installed as much as possible in clean, cool, ventilated, dry, and prevent the effects of sunlight, heater or other radiation heat sources. Battery should be placed correctly, non-inclined angles.

Each battery is connected to a firm connection. UPS Battery Replacement Method 1. 2, at the A and C points of the fuse fu 5 and the diode V (2CZ200A / 800V) .

3, check the wiring error after sending the battery fuse fu. 4, remove the fuse fu5, diode V string in circuit, combined SA3, check the diode cathode about 241V, the anode is about 218V, the diode reverse. The DC bus is powered by the charger 1 # u, the battery pack GB, GB ', but due to the low battery GB' voltage, the DC load is powered by the charging machine 1 # u, the battery pack GB.

5, disconnect SA1, remove the fuse fu3, fu4. The battery pack GB 'is powered by DC bus via diode V. 6, start the charger 2 # u, and adjust the voltage to the rated value, the DC bus is powered by the charger 2 # u, the battery pack GB 'is connected in parallel.

7. The old battery pack GB is removed from the battery screen, and the direct current screen connection number is close to the positive and negative electrode, the negative electrode corresponding to the positive and negative electrode of the charger 1 # u, respectively. 8, start the charger 1 # u, make it a voltage of the assembled old battery in parallel 241V.

9, deactivate the charging machine 2 # u, the voltage of the battery pack GB 'is short-time to 235V. 10, the SA1, the charging machine 1 # u, the old battery group GB, the new battery pack GB 'is connected to the DC bus, but the voltage is higher than the new battery pack GB by the charging machine 1 # u and the old battery group GB is higher than the new battery pack GB' The voltage, so the load current is powered by the charging machine 1 # u and the old battery pack GB, but due to the reverse step of the diode V, it will not charge to the new battery pack GB '. 11, disconnect SA3, remove the new battery pack GB 'to the battery screen.

12, will be connected and connected to the diode V at both ends of the fuse fu followed by the fuse fu3. 13, fuse fu4, charger 1 # u, the new and old battery pack is connected to the DC bus, due to the use of diode V, the charging machine 1 # u, the old battery pack is only powered by the DC bus, and does not reverse the new battery pack Charge. 14, disconnect SA1, the new UPS battery group is powered by diode V to DC bus.

15, fuse fu3, diode V is short. At this time, the diode V has been lost, and it should be charged. 16, remove the old battery pack.

17, SA1, charger 1 # u and new battery pack, parallel to DC bus. Some people often think that during use of the UPS power supply, do not maintain the so-called "maintenance" battery; in fact, due to the lack of maintenance of the battery, the problem of all the faults in the UPS is quite high. The regular maintenance of the UPS power supply is important, which is not only able to maintain a good performance, but also extend the service life, and the company's safe power and power supply.
