Why can ordinary UPS power only take a few minutes?
UPS only two factors affect the use of time, one is your storage capacity (that is, total storage), and two is your power consumption. If UPS has no problem, I suggest you change a bigger power UPS.
The large UPS external batteries are all tons. A 20KVA UPS, with an external battery of about 1 tons (30 12V 100AH batteries in series). Hundreds of K UPS batteries are filled with a small room, taking into account the weight bearing problem, the battery room is much on the ground floor of the 1, battery room 4 to 8 tons of batteries are very common.
The voltage is on the low side, and the UPS can only be powered by batteries, accompanied by alarm. The new battery has not been out for only a few minutes. Monitor host will crash. When you measure the voltage is normal, should be the same line, there is a larger power load, there is a sudden start phenomenon. And the battery may be out of commission.
The battery is dead (it may be older, or the battery is too small, not a brand cell)
