If that sounds like your ideal New Year’s celebration, then perhaps – Covid permitting – you should head to Scotland to welcome in 2022. Unlike the majority of the United Kingdom, where Christmas is the center of the holiday season, in Scotland, Hogmanay, as the New Year’s celebration is known, has traditionally been the time […]

Since the only way to truly determine battery performance is to conduct a load test, we have put together this simple 7-Step Guide to Connecting our SLB Series Constant Current DC Battery Load Tester to a Battery Bank: 1. Connect the load bank to AC power and turn the unit ‘on.’ Make sure breakers are […]
Since the early days of civilization, the method by which the craft skills have been taught was through an apprenticeship program. A young person would work under an older craftsman, learning the skills to eventually ply a trade and succeed – maybe not always in the way they might have thought. After all, some of […]

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 communications, UPS, […]

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 […]

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. Capacity Testing A lead acid battery is a collection of lead-based electrochemical cells, each with a nominal voltage […]

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 battery manufacturers come […]

There are a myriad of codes, standards, guides and practices associated with lead-acid and nickel cadmium stationary batteries. A former colleague of mine and a code expert, used to say that, “the good thing about codes and standards is that there are so many of them to choose from.” The following is an extract from […]

Did you know that 85% of UPS and power system failures are due to battery failures or the improper management of them?1 Here are the five primary purposes that proper lead acid battery maintenance serves: Prolongs the life of the battery Ensures satisfaction of design requirements Determines potential failure and predicts need for replacement Ensures […]
Having just endured one of the hottest Julys on record, many people have been subjected to extremely hot environments lately. And, in some cases, where their bodies have produced or absorbed more heat than they could dissipate, people have been experiencing an abnormally high body temperature due to the failure of their body to […]
Monitor hydrogen levels and prevent hazards with the HGD-5000 Hydrogen Gas Detector. Reliable, easy to install, and equipped with alarms and real-time indicators, it ensures safety in critical environments.
