How to choose backup batteries for data center?
26 Aug 2021
Data centers are collections of servers used to host online information so that it’s accessible from anywhere. Every data center is on a quest to maximize uptime and one of the most important components of data center uptime is data center batteries. When it comes to battery types, there is two main battery types for data center that businesses use: VRLA batteries and lithium-ion batteries.
Important factors while choosing battery backup for data centers:
1) Cost consumption: The main benefit of the Lead Acid battery, however, is its cost. Many data center operators are unwilling to switch to the newer Li-ion tech because the overall cost is much too high. Lead Acid batteries are far easier to come by and much simpler to replace.
2) Charging efficiency: Lead Acid batteries have been suited to the role of back-up batteries due to their ability to provide high power over a longer period of time. For UPS systems, the need for constant power is imperative. In new Lithium-ion battery technology, the batteries are able to quickly discharge large amounts of energy and charge up much faster, essentially eliminating the need for a longer-lasting power supply.
3) Required space: The footprint of Lead Acid systems is massive and they weigh at least three times more than Lithium battery, meaning systems above ground level need reinforced floors and storage space can take up several rooms, adding to rent costs.
4) Weight: Li-ion batteries are much lighter and smaller than Lead Acid cells and their footprint is much smaller, saving you space no matter what your set-up is. This could save companies renting space and could also help the need to reinforce floors in battery rooms.
5) Cooling capacity: Lithium batteries can perform at the same efficiency at 30 degrees as Lead Acid batteries do at 20 degrees. That means data centers adopting Lithium batteries can switch from Air conditioner to natural air, meaning further savings to your overall maintenance.
6) Life time: VRLA batteries have a service life in the range of 3-6 years, whereas lithium-ion batteries can have a service life in the range of 10-15 years, making savings in replacement over a longer period of time.
While standard data centers will most often use Lead Acid battery cells, major corporations already made the move to the more modern Lithium-ion batteries .EverExceed has specially optimized lead acid batteries and lithium batteries to build safe, reliable and scalable data center. The most common and recognizable Lead Acid batteries used in data centers are the Valve-Regulated Lead Acid (VRLA) cell which have long life and deep cycling ability . Whereas Lithium-ion batteries are not just a viable alternative to VRLA; in many cases, they are becoming the preferred option. EverExceed UPS Lithium batteries deliver energy and power density multiple times as compared to VRLA batteries.
