The 4th edition of Batteries in a Portable World contains large volumes of firsthand information that is not available in the 3rd edition of the book with same title. The 4th edition would have grown beyond 360 pages had the...
Learn how extreme cold and high heat reduce charge acceptance, and the battery must be brought into moderate temperature conditions before charging. Learn how to extend battery life by moderating ambient temperatures.
Find information about charging Nickel-cadmium batteries, full-charge detection by temperature & voltage signature and charging flooded Nickel-cadmium batteries. Learn how to maximize charge, minimize heat and reduce memory.
Learn about primary batteries. They fill an important niche market in applications such as wristwatches, remote controls, electric keys and children’s toys.
Learn what is the C-rate; created by Charles-Augustin de Coulomb, today the battery industry uses C-rate to scale the charge and discharge current of a battery.
Explore why some battery packs pose odd voltages and how this affects the user. The voltage varies depending on the metals and acid solution (electrolyte) used.
Review simple guidelines for charging Lithium-based batteries and prolong battery life such as; a portable device should be turned off while charging and more. Find out how to prolong battery life by using correct charge methods.
Review battery charge and discharge rates and read about different discharge signatures and explores how certain patterns can affect battery life. Learn how certain discharge loads will shorten battery life.
A good charger provides the base for well-performing and durable batteries. In a price-competitive market chargers often receive low priority. The battery and charger must go together like horse and carriage (Figure 1), and this is not always the case...
Electrolyte serves as catalyst to make a battery conductive by promoting the movement of ions from the cathode to the anode on charge and in reverse on discharge. Ions are electrically charged atoms that have lost or gained electrons. The...
The reusable alkaline was introduced in 1992 as an alternative to disposable batteries. The battery was promoted as a low-cost power source for consumer goods. Attempts were made to open markets for wireless communications, medical and defense. But the big...
Learn about modern Lead battery systems such as; the Firefly Energy battery, the Altraverda, the Axion Power e3 Supercell, CSIRO Ultrabattery and the EEStor.
Discover advancements made in lead acid batteries and how they benefit industry. Batteries covered are: Firefly Energy, Altraverda Bipolar, Axion Power and more.
Learn about the differences within the lead acid battery family; the sealed lead acid (SLA), also known as gel cell, and the valve-regulated lead acid (VRLA).
Read an essay on the sharing of battery knowledge and share your opinions. This interface gives me an advantage in learning how the battery behaves in the field.
Early batteries of the 1700s and 1800s were mostly encased in glass jars. As the batteries grew in size, jars shifted to sealed wooden containers and composite materials. There were few size standards, except perhaps the No. 6 Dry Cell...
Explore how batteries can be charged with solar power or a wind turbine. This is an exciting way to step outside our four walls and use renewable energy. Learn about charging your batteries from renewable resources and what it costs.
Invented by the French physician Gaston Planté in 1859, lead acid was the first rechargeable battery for commercial use. Early models were flooded, and during the mid-1970s the sealed or maintenance-free versions emerged in which the liquid electrolyte is transformed...
Discover the different battery formats that go back to the late 1800s; from the F cell to the AAAA cell to the 26650 Larger Li-ion battery for industrial applications.
Compare the pros and cons of the cylindrical cell, button cell, prismatic cell and the pouch cell which surprised the battery world with a radical new design.
Learn about the lithium-ion battery; its advantages, such as high energy density and low maintenance, and its limitations, such as transportation restrictions.
After fewer than 100,000 flight hours, two main batteries in the Boeing 787 Dreamliner failed. This contradicts Boeing’s estimate as part of certification that a smoke event involving the new Li-ion battery should only occur once in 10 million flight hours.
Learn about lithium-ion batteries and their different types. They have high energy density, relatively low self-discharge but they also have limitations.
Learn what causes Li-ion to fail and what to do in case of fire. Battery makers are obligated to meet safety requirements, but less reputable firms may cheat.
The fuel cell enjoyed the height of popularity in the1990s when scientists and stock promoters envisioned a world run on clean and inexhaustible resource – hydrogen. They predicted cars running on fuel cells and households generating electricity from back-yard fuel...
Watch for limitations when using a battery at adverse temperatures and how to overcome the effects. Explore the limitations when operating a battery at adverse temperatures and learn how to minimize the effects.
Learn about battery types and how different battery systems are used worldwide, explore future trends and discover which chemistries are most promising.
