How to check the quality of UPS lithium batteries? I believe everyone will have this idea. Generally, battery manufacturers use specialized instruments to test and judge the quality of lithium batteries, but users do not have such specialized instruments. So how should users make judgments? Let's follow the manufacturer to find out.

How to judge the quality of UPS lithium batteries?

1. Simple surface recognition. Just like the four diagnostic methods of traditional Chinese medicine. When checking, the first thing to check is the consistency of the surface, such as the appearance of the lithium battery UPS, which has wood, deformation, or protrusions. If such a situation occurs, it indicates that the organic chemical structure inside the lithium battery has been destroyed, so it belongs to the team that must be cleaned first.

2. In addition to observing deformation, it is also necessary to observe the situation of water leakage, cracking, bursting, burning, or exposure of internal liquid at the screw connection of the wood. Generally, these rechargeable batteries have serious product quality issues. Not only should we not choose this batch of lithium UPS with defective appearance, but it is also not recommended to choose rechargeable batteries from the same manufacturer to prevent safety production accidents and various common faults during the entire application process.

3. Internal loads must be accurately measured. After confirming that there are no abnormalities in the appearance, the general next step is to make the lithium battery UPS withstand a certain load in working mode. If the charging and discharging time of this lithium battery UPS cannot meet all normal charging and discharging times, or if the battery still cannot respond to all normal standard reserved time after sufficient charging time, it indicates that this rechargeable battery is already fragile and there is no need to consider the daily application of lithium batteries.
