What’s UP(S) with lithium-ion batteries?
Webinar on demand
Uniquely qualified to handle edge computing's load requirements, lithium-ion UPSs represent a significant progression in UPS battery technology, which for decades has been dominated by valve-regulated lead acid (VRLA). As lithium-ion batteries offer an 8- to 10-year life cycle — as opposed to their lead acid counterparts, which generally need to be replaced every 3 to 4 years — the technology offers several advantages.
For instance, IT professionals can easily deploy lithium-ion UPSs without the maintenance and refresh challenges of those utilizing lead acid. The extended battery life provided by lithium-ion enables users to align their UPS refresh cycles with the rest of IT stack, saving time and money spent on labor and replacement batteries. Furthermore, lithium-ion UPSs boast a “set it and forget it” value proposition, which is especially conducive at sites where UPSs protect critical network operations yet IT resources are not extensive.

Common FAQs
- Do lithium batteries pose a higher fire risk than VRLA batteries?
While any battery has the potential to catch fire if abused, lithium has a reputation for more dramatic ‘thermal events.’ However, in UPS applications, the presence of a Battery Management System (BMS)—which controls charge rate, voltage and temperature—makes lithium batteries less likely to enter thermal runaway than traditional UPS batteries. With proper storage, charging, and discarding procedures, it is unlikely for lithium-ion batteries to fail or catch fire. - Can lithium be mixed with other types of batteries (for example, VRLA)?
No, lithium cannot be put in series or parallel with other types of batteries. - Do lithium-ion batteries have recycling and/or disposal issues?
Eaton has launched its first Lithium-ion battery recycling program in APAC, with the signing of a partnership agreement with TES, one of the world’s leading providers of sustainable technology lifecycle services.
