How should UPS batteries be maintained?

How to maintain UPS battery? A very important part of UPS power supply is battery. Now, most small and medium-sized UPS power supplies are sealed with maintenance-free lead-acid batteries. Although it should not be maintained on the surface, if you do not pay attention, it may be problematic and expensive. Data from the UPS power patch indicates that approximately 30% of UPS power failures are actually battery failures. Therefore, the key to maintaining UPS power is to maintain the battery. Relatively speaking, the battery is more delicate, and it is required to work in an environment of 0~30°C, and the efficiency is highest at 25°C. Therefore, we must pay attention to the operating environment of the UPS power supply in winter and summer. High temperature will shorten battery life, and at low temperature, the nominal delay will not be reached. 1. Punctuality. Generally, UPS power supply should be given half a year to measure the battery voltage. Assuming that the voltage of 1V should be used to balance the constant voltage current limit (0.5A) charging, if there is no effect, only replace the battery. Assuming that the local power supply is uninterrupted for a long time, it must be manually supplied in time (3 months) to discharge the UPS power supply with load. Because the power has not been cut off for a long time, you always think that it is in normal operation. In fact, once power is supplied, it can only supply a very short delay, or even no delay at all, because the battery float charge is very long Time situation. 2. Beware of lightning strikes. Lightning strikes are the natural enemy of all electrical appliances. Care must be taken to ensure the effective shielding and grounding maintenance of the UPS power supply. In addition, the UPS power supply should be placed in a place with good ventilation and heat dissipation. 3. Should the battery of the UPS power supply be filled with water on time? UPS power supplies generally use lead-acid sealed maintenance-free batteries. This kind of battery uses common technology to greatly reduce the loss of battery electrolyte. Do not add water in time. This kind of battery also has the advantages of small size, high specific energy and no pollution. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
