Will the service life of the lithium battery be longer when the UPS battery is replaced?

Taking into account factors such as load conditions, use environment, service life and cost, in order to ensure the reliable, stable and safe operation of the system, it is generally recommended to replace the UPS battery every 5 years, depending on the actual situation. The maintenance-free storage battery for UPS power supply generally has a life span of 3 to 5 years. Some users will also be equipped with long-life models, such as 8 to 10 years, the longest can reach more than 20 years. The normal life of the UPS battery is relatively long. It can be used for 5-8 years if it is properly used once a month and is discharged on time for maintenance. After that, the capacity will drop significantly and it is necessary to consider replacing the UPS power battery. UPS lithium batteries have a strict number of charging cycles, usually around 1000-1200 times, and their life span is 3-5 years. Lithium batteries can generally be charged and discharged 300-500 times. It is best to discharge the lithium battery partially rather than completely, and try to beware of frequent full discharge. Generally speaking, the service life of lithium battery UPS is about 6-10 years, while the conventional lead-acid battery needs to be replaced in 2-3 years. Although the price of lithium battery is more expensive than that of lead-acid battery, it is considered comprehensively. Generally speaking, lithium batteries are more cost-effective. The life of a lithium battery is generally 300 to 500 charging cycles. Assuming that the power supplied by a complete discharge is Q, if the reduction in power after each charging cycle is not considered, the lithium battery can supply or supplement 300Q-500Q of power in its life. From this we know that if you charge 1/2 each time, you can charge 600-1000 times; if you charge 1/3 each time, you can charge 900-1500 times. By analogy, if it is charged randomly, the number of times is uncertain. In short, no matter how it is charged, it is constant to add a total of 300Q to 500Q of power. The current universal lithium iron phosphate battery UPS power supply is charged 1500 times without memory effect, about 85% of the storage capacity after 1500 times, while the life of lead-acid batteries is about 500 times, and the memory effect is distinct. Therefore, the UPS battery life will be longer after replacing it with a lithium battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
