Eaton Lithium-ion Batteries

FAQ - Lithium Ion Batteries

The most common reason cited by our customers is the significantly longer service life. With lithium-ion, IT professionals can easily deploy lithium-ion UPSs without the maintenance and refresh challenges of traditional lead acid batteries. The extended battery life enables users to align their UPS refresh cycles with the rest of their IT stack, saving time and money spent on labour and battery replacement. This "set it and forget it" value proposition is especially conducive at sites where operations are critical yet IT resources are constrained. Lithium-ion also provides a greater cycle life (the number of charge/discharge cycles extends into the thousands, versus approximately 500 for VRLA batteries), as well as a longer standard warranty. Additionally, lithium-ion UPSs can provide more runtime in the same footprint without the need for external battery modules (EBMs). Many customers have also found the lighter weight of a lithium-ion to be an added benefit.

With lithium-ion, UPS operators can play a role in helping energy providers balance power generation and consumption with the EnergyAware solution. EnergyAware enables facilities to support sustainable energy solutions, optimise the cost of powering their buildings and create additional revenue streams from their power protection assets.

Yes, we are comfortable and confident that all the vendor products we offer are safe, when used with our UPS, installed per the manufacturer's recommendations, and when their environmental requirements are observed. The battery management system (BMS) is one component which ensures the safe operation of the battery, by monitoring temperature, voltage balance, etc. and it has the ability to disconnect the battery string if conditions warrant. The other component is the design of the battery cells and battery modules. All of our vendors comply with UL1642 (Battery cell safety); UL1973 (Battery module/cabinet safety). The BMS complies with UL1973 which pulls in UL991 and UL1998 (Software safety) as appropriate.

Yes, Eaton offers lithium-ion battery retrofit systems, which include new cabinets and batteries, for several of our UPS products. The field engineer will need to make minor firmware modifications to the UPS. However, we cannot deploy a mix of VRLA and lithium-ion batteries for the same UPS system.

The longer lithium-ion battery life of the UPS – 2x battery life vs VRLA – can eliminate the cost of procuring replacement batteries as well as the labour cost for in-person battery replacement. So while it is true the capital expenditure is higher for lithium-ion, the lower OPEX costs can offset the up-front investment for many customers.
