Best Practices for Battery Maintenance and Testing

Date: Thursday, March 22nd, 2012

Location: SRP Information Services Building (ISB), 1600 N Priest Dr, Tempe, AZ 85281

Speaker: Len Holets, Megger

Topic: "Best Practices for Battery Maintenance and Testing"

Batteries are often installed and ignored. As natural disasters demonstrate, battery maintenance cannot be taken for granted. This presentation will cover safe testing methods for battery systems. Aside from the fact that battery chemistry changes over time, you have to have a plan in case of disaster. Run the "what if" scenarios. What if my batteries die after a storm event? What if a tornado strikes and takes out the grid? Do I have backup banks? Do I have maintenance records? We will look at some of these scenarios and you can assess your readiness plan. We will look at some normal battery failure modes without a natural disaster to affect their performance. We will look at positive grid corrosion, plate sulfation, sediment, and dry-out (with VRLA batteries), and how these things can happen: Could this be a pre-cursor to thermal runaway? If you know what to look for and have the right tools, batteries should be easy to maintain.
