| In the new millennium the laptop has become number 1 device widely used by students, businessmen, tourists etc. It is portable and can be taken on board an aircraft to watch movies or send/receive messages from co-workers or business partners. Nonetheless, the laptops cannot run 24/7 non-stop. Every now and again the laptop battery requires re-charging. Scarcely has anybody thought, when the first laptop battery appeared and what it looked like. In fact, the laptop battery has an exciting history. They have been updated and upgraded a lot of times, but they still have a long way to go to perfection. When we think of batteries for laptops, many of us think about the rechargeable ones that we deploy now. Nonetheless, in the past AA batteries were widely deployed in laptops. It took a lot of AA batteries to run a laptop. Besides, it could not run for long. Some people remember the heavy lead acid based batteries that did not only last long, but also made a laptop exceedingly heavy. Since then the manufacture of laptop batteries has been updated and upgraded. Lighter nickel cadmium batteries (NiCd) substituted lead acid based ones. However, these batteries were not deployed a lot, as there were developed nickel metal hydride batteries (also called NiMH). They lasted far longer and were lighter. Their main drawback was that they possessed the so-called memory effect. If the NiMH laptop battery had not discharged completely, it remembered it and produced less energy than it could do. When lithium ion batteries (LiON) entered the market, customers witnessed a tremendous advancement in laptop batteries production. These batteries are light-weight and have not got any memory effect. They are used in technically advanced laptops. Though LiON laptop batteries run for several hours non-stop, they need to be re-charged. Because more and more people buy laptops yearly, the demand for durable batteries is rapidly increasing. There will certainly be improvements until batteries that do not require to be re-charged are made. No matter what you deploy your laptop for, you know that you require a battery with a longer life. You need to know the battery will die when you need your portable pc most of all. |
