BBU and UPS Battery
What is a BBU Battery?
A BBU (Battery Backup Unit) battery refers to the high-performance backup power pack used in telecommunications and network infrastructure. BBUs are typically installed in cell towers, base stations, data centers, or remote nodes to provide DC power (often –48V) during grid outages. Modern BBUs rely on lithium‐ion (or LiFePO₄) cells for compact size and durability – in fact, industry experts note “there’s no better option for a Battery Backup Unit (BBU) than lithium‐ion” due to its high energy density and long life. Unlike simple UPS systems, telecom BBUs often include built-in intelligence: they monitor state-of-charge (SoC) and state-of-health (SoH) and can communicate battery status remotely. For example, 5G BBUs require sophisticated monitoring to report battery health and charge level so that the network can gracefully manage power in critical nodes.
What is a UPS Battery?
A UPS (Uninterruptible Power Supply) battery is the storage cell pack inside an AC backup system for computers, servers, and industrial equipment. In a UPS, the battery is coupled with power electronics (inverter/charger) so that if the mains fail, the UPS “always delivers power from a reservoir of clean power” without interruption. In other words, UPS batteries provide seamless AC output to devices by continuously converting stored DC power into filtered AC voltage. Because of this, a UPS typically offers more advanced protection than a simple battery backup – it conditions power (protecting against surges, brownouts, etc.) as well as storing energy. Large Power’s UPS battery modules use the same premium lithium technologies as our BBU packs, but are assembled to fit rack-mount or cabinet-style UPS systems used in critical facilities. We also serve industrial UPS and backup-power markets, customizing voltage and format (12V, 24V, 48V, etc.) and providing integration options so our packs can be dropped into servers, switchgear, or OEM systems with minimal adaptation.
