How to confirm the age limit of the UPS battery in the equipment room?

The UPS battery usage time in the computer room far exceeds the normal usage time. The battery can generally be used for more than 1 year in normal use. It can be judged whether the battery is scrapped or not according to the conditions of use and operating conditions. When the following phenomena occur, it can be judged that the battery has reached its final working life and should be scrapped. 1. The actual discharge capacity of the UPS battery is less than about 60% of the rated capacity, and the battery whose performance cannot be restored after repair must be scrapped. Generally, when the capacity of a battery decays to about 60%, its performance will be greatly attenuated, and it will quickly lose its charge and discharge capabilities. Its performance is that it overflows quickly in a short time, and then discharges quickly, unable to store power, and discharge The time is short. 2. Severe heat when charging the battery and deformation of the casing. When the plate of the UPS battery softens and deforms, the active material falls off, and the electrolyte in the pool becomes black, and it cannot be repaired if it is seriously invalid. At this time, the battery charges and discharges quickly. 3. When the battery life ends, use a multimeter and ammeter to detect its voltage and current. Their values u200bu200bare very low, the performance of the battery decreases, and there may be short-circuit or open circuit in the battery. The battery should be replaced in time.
