The battery pack is an important part of the UPS system, and its cost is also high. Therefore, when the UPS system runs for a certain period of time and needs to be replaced to ensure the reliability of the UPS system, the user will always ask what is the standard for replacing the battery pack, and are there any relevant specifications and requirements? ? In fact, there is no mandatory requirement to replace the battery pack. The following are two reference indicators of battery life that have been edited and arranged for customers to refer to.

1. Floating charge life refers to the number of years that the battery can be used when the battery can be discharged at a standard temperature with continuous floating charge and discharge not less than 80% of the rated capacity.

2. The number of 80% deep cycle charge and discharge is the number of times the battery with full capacity is fully charged after being discharged to 80% of the rated capacity.

According to relevant regulations, when the rated capacity of the battery pack is lower than 80% of one of the two cases, it is recommended to replace the battery pack.

So how to judge the capacity of the battery pack? To judge the battery capacity, you can use a battery internal resistance tester to test the current internal resistance of the battery. When the internal resistance of the battery increases to 1.5 times the internal resistance of the factory, it means that the battery capacity has dropped below 80%, and it is recommended to replace the battery pack.

The above is the edited and sorted UPS battery replacement standard. You can refer to this. Since there are too many industries and scenarios for UPS applications, with different standards and requirements, it can be flexibly referenced and implemented in different industries.
