Vented lead-acid battery electrolyte levels are affected during the charge and discharge cycle due to the chemical reaction taking place inside the cell. A battery that is starved of electrolyte will not perform as expected.
Failure modes for stationary power Vented Lead Acid (VLA) batteries and the cause of failure in Valve Regulated Lead Acid batteries (VRLA) have been increasingly understood as the industry has continually utilized them in Telecommunications, UPS, and Utility applications at a growing rate.
The most critical aspect of evaluating true health of a battery are the measurements of the internal cell conductivity of each individual battery. Correctly and accurately capturing these measurements for gathering of historical battery information to predict the health and service life of a battery must be of topmost importance.
In our industry we often hear, “Why does my 20 year battery only last 12 years?” Or, “Why does my 10 year battery only last 7 years?” Well, the answer lies in knowing the difference between battery “Design Life” vs “Service Life” expectations.
One thing is certain, we all rely on technology to keep our businesses, our homes, and our entire infrastructure operating on ’round the clock demand. Satisfying that demand requires dedicated maintenance, testing and monitoring of operational and backup systems -- particularly in the telecommunications, data center and utility industries.
All it takes is one disaster to reveal the weakness of an emergency backup system in a telecommunications network. A loss of backup power during an outage can cause not only lost business, but also lost employee productivity and costly repairs.
