5 Considerations for Maximizing the Life of Your UPS Batteries

UPSWe often get asked:  How long will my UPS battery last? Well, it depends.

No battery lasts forever. And battery life can be maximized by operating your uninterruptible power supply under recommended conditions (check your user manual).

Generally speaking, the life of your UPS battery depends on:

  1. UPS Placement – We recommend in
    stalling 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.
  1. Ambient Temperature – The rated capacity of a UPS battery—the conditions that maximize its 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.
  1. Cycling Frequency – At installation, a battery is at 100 percent of its rated capacity. But each discharge cycle (in other words, every time it goes to battery) will slightly decrease its relative capacity. Understanding cycling frequency allows you to notice abnormal or frequent cycling so you can better predict its life. Many UPS models are also adjustable so you can reduce “nuisance trips” that can unnecessarily consume battery capacity.
  1. Maintenance – “Maintenance-free” UPS batteries do not require replacement fluid, but they do require periodic maintenance. 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.
  1. Battery Storage – To avoid the consequences of downtime, many UPS owners may purchase replacement batteries before they’re needed. Just make sure to charge stored batteries every six months or they will suffer a permanent loss of capacity within 18 to 30 months.
