What is an electrical substation? It is that part of the electrical generation, transmission and distribution grid, that contains equipment that transforms line voltage from high to low and vice versa. The locations can also contain other elements such as protection and communications equipment. All of these critical elements are backed up by batteries. It […]
Understanding Thermal Challenges in Stationary Battery Systems Stationary lead-acid batteries are designed to operate under certain environmental conditions such as temperature, humidity and cleanliness. Operating outside these constraints has many effects on batteries. Most battery warranties are based upon operating conditions This webinar will define the desired conditions and what happens to the battery during […]
Navigating the Latest Codes and Standards for Lead-Acid Batteries Things change, and that certainly applies to rules and regulations, codes and standards. This webinar will bring stationary battery users, installers and maintainers up-to-date on what is happening in the regulation minefield that surrounds your batteries. What documents apply? What is enforceable by law? Where do […]
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. Lead Acid Battery Charging Techniques Constant-Current Charging: Not generally used for stationary batteries except during the manufacturing process. Constant-Potential / Constant Voltage […]
Listen in this episode of DC Power Hour as our Battery Blarney Duo of George and Allen welcome George Turner, another industry veteran who recently joined Eagle Eye as an advisor/EEU instructor. They discuss and recollect the evolution of batteries over the span of their careers. Episode Highlights 0:59 – I (George Turner) started in […]
Introduction Originally, lead-acid batteries consisted of pure lead grids; but lead is very soft, difficult to work with and to transport. Gaston Planté, who is credited with the invention of the lead-acid battery, refined the lead plate. A modern form of pure lead plates, the Planté plate, named after him, although expensive to manufacture, is […]
First of all, a definition Ripple is the AC component of a system’s charging voltage imposed on the DC bus. It can also be reflected from load equipment. It could be caused by poor charger design, poor inverter design, failing capacitors, or by the interaction of load equipment connected to the DC bus. The result […]
These type of batteries should never be referred to as “sealed” or “maintenance-free” batteries because they are neither. Definitions The Absorbed Glass Mat (AGM) technology is also sometimes referred to as “Absorbed Electrolyte”, “Immobilized Electrolyte” or “Starved Electrolyte.” They derive the name from the methodology used to immobilize the liquid dilute sulfuric acid electrolyte. A […]
Your battery is only as good as how you charge it All too often, stationary batteries are not correctly or adequately charged. This leads to a shortened battery life and may also cause a premature and sometimes catastrophic battery failure. It is the author’s experience that almost 50 percent of all stationary batteries are not […]
The Battery Blarney Duo are joined by industry experts Al Warner and Dan Lambert to discuss lead acid, lithium, nickel cadmium and other prominent battery chemistries and their proper applications. They discuss the pros and cons of these popular chemistries as well as the prospect of other interesting options, like that of zinc manganese. The […]
In this episode, George and Allen set the record straight on lead-acid batteries. They talk about the origin and history of batteries, including French physicist Gaston Plante and his invention of the rechargeable battery. George and Allen discuss battery lifespan and challenges with different battery types over the years, as well as the importance of […]
