How to extend the life of UPS battery

How to prolong the life of UPS battery power ●Try not to connect inductive loads. Because the starting current of the inductive load will often exceed 3 to 4 times the rated current, this will cause instantaneous overload of the UPS and affect the life of the UPS. Inductive loads include electric fans and refrigerators commonly used in summer. ●It is not suitable for full load or excessive light load. Do not use it according to the rated power of the UPS, and do not think that the empty interface should not be connected to other electrical appliances. The long-term full load state will directly affect the UPS life. Under normal circumstances, the load of the online UPS should be controlled at 70% to 80%, and the load of the backup UPS should be controlled at 60% to 70%. Note that excessive light load is not good, although not as serious as overload. ●Protect the battery. A very important part of the UPS is the battery. At present, most small and medium UPSs use sealed lead-acid batteries that do not require maintenance. Although on the surface it does not need to be maintained, but if it is not well taken care of, it will also have problems, not to mention this kind of battery is quite expensive. Data from the UPS maintenance department shows that about 30% of UPS damage is actually just a broken battery. Therefore, the key to maintaining UPS is to maintain the battery. In comparison, batteries are more delicate and require working in an environment of 0 to 30°C, with the highest efficiency at 25°C. Therefore, we must pay attention to the working environment of UPS in winter and summer. High temperature will shorten battery life, and low temperature will not reach the nominal delay. ●Regular maintenance. Usually, the terminal voltage of the battery should be measured for UPS in half a year. If the voltage exceeds 1V, you should use a balanced constant voltage current limit (0.5A) for charging. If it does not work, you can only change the battery. If there is no power outage in the local area for a long time, the power supply must be interrupted artificially at regular intervals (three months) to discharge the UPS with load. Because it has not been powered off for a long time, you always think it is working normally, but in fact, once the power is off, it can only provide a short delay or even no delay at all. The reason is that the battery is in a floating charging state for a long time. . ●Pay attention to lightning protection. Lightning strikes are the natural enemy of all electrical appliances, so care must be taken to ensure the effective shielding and grounding protection of the UPS. In addition, the UPS should be placed in a place with good ventilation and heat dissipation. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
