1. Simple surface recognition. Just like the four diagnostic methods in
traditional Chinese medicine. When checking, the first thing to consider is the
consistency of the surface, such as the appearance of the lithium battery UPS,
which may have 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 cleared first.
In addition to observing deformation, it is also necessary to check for
water leakage, cracking, bursting, burning, or exposure of internal liquid at
screw connections in 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 accidents
and various common faults during the entire application process.
3. It is necessary to accurately measure the internal load. After
confirming that there are no abnormalities in the appearance, the next step is
usually 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 very fragile and there is no
need to consider the daily application of lithium batteries.
