Battery Technology for Data Centers and Network Rooms: Site Planning

Posted by on June 18, 2012  |  No Comments

White Paper 33

Batteries for uninterruptible power systems (UPS) are almost universally of the lead-acid type and are of one of the following three technologies:

  1. Vented (flooded or wet cells
  2. Valve regulated (VRLA)
  3. Modular battery cartridges (MB)

Please refer to White Paper 30, Battery Technology for the Data Centers and Network Rooms: Lead-Acid Battery Options , for more details.

Executive Summary:

The site requirements and costs for protecting information technology and network environments are impacted by the choice of uninterrupted power supply (UPS) battery technology. This paper will discuss how battery technologies impact site requirements.


  • Adaptability
  • Planning issues


IT systems present a rapidly changing requirement for data center infrastructure. Fast response to this change can be difficult but can be facilitated by the appropriate selection of UPS battery technology.

The different battery technologies now available vary considerably in their site planning requirements and in their ability to create battery systems that can adapt to changing requirements.

A typical data center design process focuses on power and runtime as the drivers in battery selection and cost. An alternative approach is to focus on how adaptable the battery system needs to be to changing requirements. This approach can give rise to dramatic savings over the life of the system.
