In the XXI century the laptop has become number 1 device widely deployed by students, businessmen, travellers etc. Since it is portable, it can be taken aboard a plane to view films or send/get messages from colleagues or business partners. Still, the laptops cannot work day and night. At times the laptop battery requires re-charging. Scarcely has any user thought astir the first laptop batteries and their power. In fact, the history of laptop batteries is an exciting one. They have been updated and upgraded a lot, but they still have a long way ahead to perfection. When we think about batteries for laptops, many of us think about the rechargeable ones that we use now. However, a few decades ago AA batteries were widely used in laptops. It took a great many AA batteries to run a laptop. Moreover, it could not run for long. Some laptop users remember the heavy-weight lead acid based batteries. Neither lasted they long, nor were they light. The manufacture of laptop batteries has changed since then. Lead acid based batteries were superseded by lighter nickel cadmium batteries (NiCd). Nevertheless, these batteries were not deployed long, since nickel metal hydride batteries (differently called NiMH) appeared. They lasted longer and were lighter. Their main drawback was the so-called memory defect they had. If not discharged to the full, the NiMH battery remembered it and put out less power than it should do. When lithium ion batteries (LiON) entered the market, users witnessed a tremendous progress in laptop batteries production. These batteries are light and do not produce any memory defect. They are deployed in technically advanced models. Though LiON batteries run non-stop for several hours, they require to be re-charged. Because more and more people get laptops annually, the demand for durable batteries is rapidly increasing. There will definitely be further improvements until laptop batteries that never go dead are produced. Regardless of the purpose you switch on your portable computer for, you know that you need a long-lasting battery. You need to know the battery will die when you need your portable computer most of all.
