In general, the backup time of commercial UPS battery is not as long as in industrial applications, usually in the 10-30 minutes or so, the charging capacity does not require the capacity increasing design. UPS battery charger is generally designed to be able to back the lead-acid batteries, which back up time is 15-30 minutes, to the capacity of 95% in 8-10 hours.Compared with the commercial UPS, in industrial applications, charging capacity must have higher ability, because the battery backup time from 60 minutes to 8 hours or more, which requires the charger in the UPS system has enough battery recharge capacity. In many cases, the use of backup time for 4-8 hours of battery configuration. In the industrial field of UPS, in order to better adapt to the demand of high and low temperature environment, nickel cadmium batteries have been widely used, in addition to meet the industrial grade UPS charger for lead-acid batteries, also need to meet the charge and discharge characteristics of the nickel cadmium battery.
