Vertiv EXSV-EBC2 External Battery Cabinet 37.5 Ah | VRLA UPS

When backup time matters, an external battery cabinet gives the UPS more room to do its job. The Vertiv EXSV-EBC2 adds 37.5 Ah of VRLA battery capacity in a 2-string configuration, helping extend runtime for critical infrastructure that cannot afford a short transfer window. It is a practical choice for data rooms, network closets, and edge sites where every additional minute of power support can prevent disruption. This cabinet is designed for teams that need more than a standard internal battery set can provide. By moving runtime expansion into a dedicated external enclosure, it supports better planning for graceful shutdowns, generator start intervals, and short-duration outages. That makes it especially useful in environments with distributed IT, remote facilities, or systems that must stay online long enough for operators to respond. Compared with smaller battery options, an external cabinet gives you a cleaner path to runtime expansion without replacing the UPS platform. It is the right move when the load is important, the outage window is uncertain, and backup capacity needs to scale with the environment.
