Batteries are the heart of the UPS system that protects your computers and other electronic equipment from power fluctuations. UPS units use high-current batteries that can handle power spikes, dips, blackouts and line noise. Most UPS batteries are sealed lead acid and designed to last from five to eight years.
UPS Battery Life
A UPS battery reaches the end of its useful life when it can no longer supply 80 percent of rated capacity. After this point, capacity and backup time degrade quickly. For example, a battery that normally provides 15 minutes of backup may have seven minutes at 80-percent capacity. This degradation is most often due to corrosion of the positive grid's inner wires. You can prolong your battery's life by keeping it clean, maintaining connectors and cables, and regularly checking performance.
Sealed Lead Acid Batteries
Sealed UPS batteries don’t require you to add water although they do need preventive maintenance. Absorbed glass mat (AGM) batteries are ideal for UPS
