Add runtime where it matters with the Vertiv MPL 2U Li-Ion External Battery. Built for rack-based power environments, this external battery module gives compatible MPL systems additional energy storage in a compact 2U form factor. For IT teams balancing uptime, density, and service access, that matters. Lithium-ion battery technology is a strong fit for modern infrastructure because it supports a smaller footprint than many traditional battery approaches while helping simplify long-term power planning. In edge rooms, micro data centers, and distributed network sites, an external battery module can be the difference between a controlled shutdown and an abrupt interruption. This module is designed for organizations that need more than basic ride-through. It supports backup power expansion for critical switches, servers, storage, and communications gear, while preserving rack space for the rest of the stack. When uptime is measured in business continuity, a dedicated external battery solution is a practical investment — especially when the cost of downtime exceeds the cost of doing power right the first time.
