How to estimate the remaining UPS battery capacity?

How to estimate the remaining UPS battery capacity? Regarding UPS power supply, UPS battery is also one of the important components. How to estimate the remaining battery capacity? The dynamic calculation of battery capacity is calculated through the integration of battery current over time, which reflects the capacity of the battery charged or discharged. At the same time, it is sometimes necessary to roughly understand the quality of the battery, so it is necessary to estimate the capacity. Users can start capacity estimation to predict capacity. The basic method of capacity estimation is: After obtaining the 0.05C10A discharge voltage curve of a set of intact standard batteries, discharge the battery with a current of 0.05C10A, and compare the discharge terminal voltage and the discharged capacity at regular intervals. For example, it took 200 minutes for a standard battery 0.05C10A to discharge to 12.5V, and the measured battery 0.05C10A to 12.5V only took 150 minutes, then the static capacity of the battery is 150/200*100u003d75 of the rated capacity. In many cases, if you don't know how long the UPS battery can support after a power outage, it is too late if it is only then discovered that the battery capacity is not enough. So I hope to be able to make an estimate of the UPS battery capacity. The battery can be tested online manually when the UPS is turned on or running. This test, especially the line test with an important load, is to take risks. It is recommended that the battery only supports a short period of time. Fortunately, the energy required by the load is shared by the mains and the battery, which can prevent UPS from being caught off guard due to insufficient battery capacity. Output interruption problem. However, many UPS capacity estimates are based on the percentage directly estimated by the battery voltage. In any case, the capacity estimation is only an estimation, and the accuracy of 10 is generally quite good.
