VRLA Battery Degradation

How a Single Bad Battery can cause Thermal Runaway

Our White Paper Valve Regulated Lead-Acid Battery Degradation: How a Single Bad Battery Can Cause Thermal Runaway was written as a guide for UPS owners on how to properly support UPS batteries to prevent a thermal runaway condition.

While a majority of our customers are aware of what thermal runaway is and how to maintain their batteries, we have come across a few instances where the batteries are in thermal runaway. In most of these cases, there isn’t a certain person left in charge of the unit. The responsibility is not on a single person, or even a team. This creates an environment where the UPS or batteries will go without maintenance until they are in alarm, at which point could already have a serious issue.

This White Paper will detail:

  • What a VRLA battery is

  • How they are utilized in an Uninterruptible Power Supply (UPS)

  • What thermal runaway is

  • How to prevent thermal runaway

  • NFPA 1 Chapter 52 and how it applies to a room with batteries

  • Proper installation of batteries
