Laptop Batteries
If you are among the escalating number of mobile executives who are switching from PCs to laptops, it is inevitable that you will soon face a situation where you will need to inform yourself about laptop batteries. And then, at some point, purchase them. Here are some basic guidelines: Brief Background of Laptop Batteries: The earliest type of battery used the chemicals Nickel Cadmium and was very fast to charge and was also able to handle high loads. However, these chemicals are highly poisonous. The next generation of batteries, the Nickel Metal Hydride (NiMh, NiMH) batteries, now use Nickel and additional rare earth metals as its electrodes and Potassium Hydroxide as the electrolyte. These are more environmentally friendly than Nickel Metal Hydride, but undergo from the memory effect, and have a short lifespan. A newer type of battery is the Lithium Ion (LiIon, Li-Ion) power-driven battery. In spite of being smaller and lighter than NiCd and NiMH batteries, it provides the same competence. Also, these batteries do not suffer from "memory effect" and have low levels of self-discharging. The Lithium Polymer Ion Battery: This is the most modern type of battery chemistry. Though this behaves in the similar way as Lithium Ion, there are some important differences. The Lithium Polymer Ion Battery uses a thin plastic-like film as the electrolyte, resulting in significantly reduced weight, and a greater power to weight ratio than most of the other types. They are used in Universal Laptop Batteries. This is the sort to look for, when you need a fresh
