What determines the length of spare time?
It is determined by the UPS energy storage device. Now UPS generally uses a fully sealed maintenance-free lead-acid Vida battery as an energy storage device, and the size of the battery capacity is determined by. Ampere hours (AH)& # 39; This indicator reflects that its meaning is the time of discharge according to the specified current. The same voltage of the battery, large ampere-hours of large capacity; The battery with the same ampere hours has a large capacity with a high voltage, and the capacity of the battery is usually expressed by the voltage and ampere hours, such as 12V/7AH, 12V/24AH, 12V/65AH, 12V/100AH, 120AH.
The backup UPS generally has a built-in 4AH or 7AH battery, and its backup time is fixed; Online and online interactive UPS have built-in 7AH battery standard models, there are also long-term models with large capacity batteries, users can determine how much capacity of the battery according to the need to achieve the backup time 1, good safety performance: no electrolyte leakage under normal use, no battery expansion and rupture.
2, good discharge performance: smooth discharge voltage, smooth discharge platform.
3, good shock resistance: fully charged state of the battery is completely fixed, with 4mm amplitude,16.7Hz frequency vibration for 1 hour, no leakage, no battery expansion and rupture, open circuit voltage is normal.
4, good impact resistance: fully charged state of the battery from a height of 20cm naturally fell to 1cm thick hardwood 3 times. No leakage, no battery expansion and rupture, open circuit voltage is normal.
5, good overdischarge resistance :25 degrees Celsius, fully charged state of the battery for a fixed resistance discharge for 3 weeks (resistance value equivalent to the battery 1CA discharge requirements of the resistance), the recovery capacity of more than 75%.
6, good overcharge resistance :25 degrees Celsius, fully charged state of the battery 0.1CA charging for 48 hours, no leakage, no battery expansion and rupture, open circuit voltage is normal, capacity maintenance rate of more than 95%.
7, good resistance to high current: fully charged battery 2CA discharge for 5 minutes or 10CA discharge for 5 seconds. No conductive part is fused, no appearance deformation.
