UPS batteries provide continuous power to UPS systems during power outages. They keep computers running for several minutes after the power has been cut off, allowing users to save their work and perform a proper shutdown before the computer loses power. They usually come with indicator lights for monitoring remaining power.
Types of UPS Batteries
Kinds of UPS Batteries include the following:
Electrolytic UPS batteries
Electrolytic UPS batteries are also known as flooded wet cells. They generally have a high initial cost, but they are very reliable and durable. They can last from 15 to 20 years.
Vented UPS batteries
Vented UPS batteries are less expensive than the flooded wet cells, but they do not function as well. They can last from three to five years only. They require configuration into separate battery strings with DC breakers. One string is isolated from the UPS system to keep the system online during maintenance or replacement.
Choosing UPS Batteries (Buying tips)
Surge protection: Choose a UPS battery equipped with a surge protector to protect both the computer and the UPS system against power surges.
Warranty: Choose a UPS battery that comes with at least one year of warranty from the date of purchase. Make sure it covers all forms of damage and includes parts replacement and labor costs.
