Widely used in today’s consumer electronics, lithium-ion batteries are now being adopted as a backup energy source for Uninterruptible Power Supplies (UPS) in data centers. In UPS applications, lithium-ion batteries can provide a savings in Total Cost of Ownership (TCO) of 10-30% over lead acid batteries over a 15-year UPS system life. While the initial capital cost is still slightly higher than lead acid batteries, they can provide significant TCO savings due to lower operating costs.
