Ways to Properly Charge Stationary Lead-Acid Batteries
After hundreds of site visits, multiple battery systems tests, and the examination of numerous maintenance records, I would say that almost 50 percent of all stationary lead-acid batteries are not being properly charged. Constant-Current Charging: Not generally used for stationary batteries except during the manufacturing process. Constant-Potential / Constant Voltage Charging: Used in ...

Hydrogen Detection and Control
How Lead-Acid Batteries Release Hydrogen Lead-acid batteries produce hydrogen and oxygen gas when they are being charged. These gasses are produced by the electrolysis of water from the aqueous solution of sulfuric acid. A Vented Lead-Acid (VLA) battery cell, sometimes referred to as a “flooded” or “wet” cell, is open to the atmosphere through a flame-arresting vent, and ...

Why Do We Need Battery Monitoring If We Do Discharge Testing?
Introduction This is a question that is often asked, and the answer is relatively simple. A discharge test measures the capacity of the battery and a battery monitoring system is a maintenance tool. Let me explain further. The Importance of Capacity Testing A lead acid battery is a collection of lead-based electrochemical cells, each with a nominal voltage of 2 Volts, assembled in series to ...

“Sealed Maintenance-Free” Batteries. What a Myth!
The term “Sealed Maintenance-Free,” in my opinion, is a marketing-driven term. In the early 1980’s, when telephone Private Branch Exchanges (PBX’s) were being deployed into customer premises, computer mainframes were migrating out of dedicated computer rooms, and smaller computers were being situated in occupied office space. Consequently, users were demanding that the ...
