Battery packs achieve the desired operating voltage by connecting several cells in series, with each cell adding to the total terminal voltage. Parallel connection attains higher capacity for increased current handling, as each cell adds to the total...

Consumer market put aside, the largest users of primary (non-rechargeable) batteries are the military, specialty emergency services and forest fire fighters. High energy density, long storage and operational readiness are among their strong attributes....

Remote control (RC) enthusiasts are experimenting with all imaginable methods to maximize battery performance. A racecar motor draws 30A for about four minutes delivered by a 7.2V battery. This amounts to over 200W of power, a large amount from a small...

Declining Capacity Energy storage in a battery can conceptually be divided into three imaginary segments of the available energy,the empty zonethat can be refilled, and the unusable part(rock content). Figure 1 illustrates these three sections. Figure...

Why battery standby time more shorter than manufacturers claim All along, many consumers often complain that their laptop battery standby time is always shorter than the manufacturers claims. For this question, the laptop users must realize that. The...

The industry will be bombarded together with a number of personal computers these days and so making a choice about what sort of mobile computer to get can be quite a very puzzling knowledge and also frustrating knowledge. Many people tend to be conversant...

The performance and longevity of rechargeable batteries are to a large extent governed by the quality of the charger. In a price-competitive world, battery chargers are often given low priority, especially as consumer products. Choosing a quality charger...

A new and exciting market is opening for manganese that could provide the metal with explosive growth potential, and diversification away from it ties to the steel industry. This market is essential to the future, from high tech consumer goods, to the...

Safety is a sensitive issue that gets much media and legal attention, especially with Li-ion batteries. Any energy storage device carries a risk, and in the 1800s steam engines exploded and people got hurt. Carrying highly flammable gasoline in cars was...

Over the last decade or so, most of us have slowly found ourselves increasingly dependent on a single type of battery: a lithium battery. This has led to some interesting questions on why lithium has become the preferred choice, and what comes after lithium?...
