Regardless of how or where you deploy your UPS, its batteries will have a finite service life. While a variety of factors can contribute to the length of time a battery will remain operational, there are seven primary factors that contribute to its overall lifespan. There are mainly seven factors that effects to the battery life time and these are:

Ambient Temperature: The conditions that maximize battery life and result in optimal performance is based on an ambient temperature of 25°C (77°F). Every 10°C (18°F) above the ambient temperature will reduce the life of the battery by 50 percent.

UPS Placement: Recommend installing the UPS in a temperature-controlled environment and within specified limits and not near open windows or areas that contain high amounts of moisture, dust, or corrosive fumes. Also, keep ventilation openings free.

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? That’s because the number and length of battery discharges affect a battery’s ability to deliver power. The more discharges, the deeper the discharges, the shorter the battery’s life will be.

Age: Batteries are electrochemical energy storage devices that convert chemical energy into the electrical energy that UPS’s need to operate. But, even with battery charging, over time the chemicals in the battery deplete, which cause the battery to deliver less power and for shorter periods of time for a given load. Hence, no matter how carefully you use a battery, at some point, it’s time for battery “retirement.”

Load Sizing: If a battery is undersized for a load, battery run time and life expectancy will be shortened. You can verify your sizing with the Load and Runtime Calculator to ensure you have a properly sized battery bank for your current load.

Maintenance: “Maintenance-free” UPS batteries do not require replacement fluid, but they do require periodic maintenance. So, visually inspect batteries for cleanliness and remove any dust, dirt, or debris. Leaking batteries or batteries with excessive swelling should be properly disposed of and replaced.
