How long should a UPS battery last?
three to five years
Because the chemicals deplete over time, even UPS batteries that are well cared for will still need to be replaced. Most batteries have an expected lifespan of three to five years under ambient conditions.
What factors reduce battery life?
There are five primary factors that affect UPS battery life: ambient temperature, cycling, battery chemistry, application and maintenance.
- Ambient Temperature. The rated capacity of a battery is based on an ambient operating temperature of 25°C (77°F).
- Cycling.
- Battery Chemistry.
- Application.
- Maintenance.
Why do UPS batteries go bad?
Undercharging or low voltage can cause sulfate crystals to form on the battery plates. Overcharging with a float voltage that is too high can cause excessive hydrogen and oxygen gases and can lead to internal dryout that, once accelerated, can cause thermal runaway – resulting in failure or even fire and explosion.
How often do you need to replace UPS battery?
Typical UPS battery life is 3 to 5 years. This is dependent on a number of factors, including: Temperature where the unit is located.
What is the life of battery?
Battery life is a measure of battery performance and longevity, which can be quantified in several ways: as run time on a full charge, as estimated by a manufacturer in milliampere hours, or as the number of charge cycles until the end of useful life.
Are there any UPS batteries that don’t last?
Ambient temperature may not be a problem for UPS batteries used in air-conditioned data centers, but it could be a problem in industrial locations, unprotected environments or hot climates. 2. Number of Discharges: Have you been noticing that your UPS battery power isn’t lasting as long as it did when you first bought it?
What is the expected life of my APC UPS battery?
A battery which would last for 4 years at 25 ° C (77 ° F), will only be good for 2 years if operated at 33 ° C (95 ° F). Keep in mind that the battery temperature inside your UPS will always be warmer than the ambient temperature of the location where the UPS is installed.
How often should I charge my ups battery?
To prolong a battery’s storage life, we recommend you charge it every three to four months of storage. If you don’t, you could see a permanent loss of capacity in as little as six months. You can also prolong your unused battery’s storage life by storing it at a temperature of 50°F (10°C) or less.
What’s the energy efficiency of a UPS UPS system?
Energy inefficiency is one of the largest controllable costs in a UPS. A new UPS system can vary in efficiency from 85% to 98% in true, online mode. However, UPS systems, particularly when underutilized, can be enormous energy hogs, with as low as 40-50% efficiency in some legacy systems.
