The rechargeable battery is actually also known in other circles as a storage battery and within the structure of this battery is actually two or more secondary cells, which means that these batteries can reach their full kinetic and electrical potential with the application of electrical energy to recharge it. In the words of the scientist, the electromagnetic and electrochemical reaction that is released within the battery is completely reversible, so it can be said that the battery is a sort of an accumulator in a sense.
There are many and varying chemical make ups of these cells and the materials used are quite different and can range from lead, sulphuric acid, alkaline, nickel cadmium, nickel hydrogen and lithium of course - being the newest member of the family to outperform everything else before that. The benefits of rechargeable batteries are one and many in the sense that they give an obvious environmental benefit to the atmosphere. With rechargeable batteries, less of them gets thrown away and of course the materials used can be quite toxic to the environment in the sense that disposal can be quite disposable. Also, there are plenty of economic benefits in the sense that the cost to dispose of them properly and without any damage to the environment can be quite high and looking at the former reason, these two are intrinsically tied and corporations sometimes look for cheaper and more dangerous ways to dispose of these batteries.
Lithium Ion Tools
Some of these batteries have a service like of more than 3, 000 charge cycles - so you can see just how much savings an individual person can make on their own just by buying these and nor purchasing normal alkaline and stand alone primary cells for use with their electronic devices. The applications for these batteries are plenty and they include automobile starters, consumer devices, even some light vehicles powered by large batteries, handphones, music players and digital cameras. These are some of the products that are being used in conjunction with rechargeable batteries. Grid energy storage, a new technology in some applications actually are using rechargeable batteries for 'load leveling', where they store much of the days electric energy for use when and during peak load periods, where energy demands are the greatest as well as for renewable energy uses, such as the act of storing power generated from photovoltaic arrays during the course of the day to be used when the sun goes down at night.
By charging batteries during the latent periods of low demand and giving back this energy to the grid at large volumes during periods of high electrical need , load-leveling is a technique that helps to eliminate the need for costly peaking power plants and helps amortise the value of generators over more and extended hours of operation. These are some of the technical aspects and the uses for rechargeable batteries, and as you can see, they far out reach the normal applications and go into the arena of industrial and scientific levels.

About DEWALT
Raymond E. DeWalt followed in his father's footsteps by holding mill and constructions jobs from the time he left school. No matter what the job, the question of high labor costs always concerned him. To help cut these costs, occasionally he rigged up a machine to meet some special need. Eventually, Mr. DeWalt was offered a position as head of a woodworking mill that manufactured almost everything from boxes to full-fledged houses. He designed a yoke and attached it directly to a motor and saw, then mounted it on a standard arm. The saw could be raised, lowered, slid back and forth, moved to any angle, or tilted to any bevel. It instantly lowered costs and increased productivity, and was the first DEWALT tool. Today the DEWALT power tools line consists of over 200 electric power tools and over 800 accessories including: drills and hammer drills, screwdrivers, circular, chop, miter, table, reciprocating, and jig saws, planers, impact wrenches, die, angle, and bench grinders, shears, nibblers, sanders, laminate trimmers, routers, and plate joiners.
