Lithium-ion batteries are a common power source for millions of consumer devices. But they are now being adopted for use with Uninterruptible Power Supply (UPS) applications, as a means of ensuring uptime for mission-critical infrastructure in data centers. For companies wishing to deploy distributed computing and edge networks, lithium-ion batteries are ideal for use with IT deployments in remote locations. Lithium-ion batteries offer more reliable performance, require less maintenance, and have a higher power density than lead acid batteries. Lithium-ion batteries last 2-3 times longer than lead-acid batteries, resulting in fewer battery replacements and lower labor costs. This white paper discusses the advantages of lithium-ion batteries, including a comparison of total cost of ownership.
