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 […]
All too often, stationary batteries are purchased many months before they are destined to be put into service and they are put in temporary storage. This storage can be either away from or at the installation location. Also, sometimes batteries are installed at their intended location but are not connected to the charging system. This […]
Realistic Battery Life Stationary batteries of all chemistries are usually rated in watts or Ampere-hours (Ah) which indicates the amount of power (current) that can be delivered over a period of time. These ratings are dependent upon operating temperature and depth of discharge. They are also rated in terms of expected years of useful service […]
The Lead-Acid Battery is a sacrificial design with unavoidable degradation over time. The inside of a battery cell is a highly chemically active environment. Lead is soft, so in order to make the plates more rigid, in most of the early designs, antimony was added as a hardening agent. The percentage of antimony was high, […]
In this episode, George Pedersen of The Battery Blarney Duo answers questions about the basic concept and workings of battery backup for electric substations and their critical components. He touches on topics including ensuring the stability and reliability of the electricity grid, reducing the risk of equipment damage, keeping communications systems powered and preventing costly […]
The discussion about the chemistry and applications of batteries continues in this episode with Al Warner, Dan Lambert, and The Battery Blarney Duo. They compare flow and lead acid batteries in terms of their reliability and need for maintenance. They examine the problems with energy-storage batteries, such as a zinc manganese battery, as well as […]
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, the Battery Blarney Duo, George and Allen, discuss the challenges of battery warranty and why battery maintenance is important. Many battery problems can be attributed to a lack of maintenance, as well as other things like operating temperature, how long they are on a shelf before put into use, the way the […]
The Battery Blarney duo of George and Allen welcome Ed Rogers, National Service Support Manager at EnerSys, to talk about the critical nature of stationary battery charging. The topic of proper battery charging is one of Allen’s passions and they discuss what happens when you undercharge and overcharge a battery. All batteries are not equal […]
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 […]
In the first section of this episode, George and Allen discuss the importance of battery maintenance. They talk about the problems they have seen due to a lack of maintenance, and how catastrophic it can be. The costs due to the battery failure can reach millions of dollars. Lives could be lost potentially. But there […]
