Laptop lithium battery tips

We often set our sights on price, weight, figure and configuration when we purchase a new laptop. Battery is often ignored. In fact, battery and integral performance of a laptop are inseparable. Battery is as important as CPU, mainboard, hard disk etc. We list the tips and guideline below. Let's get the most of your lithium laptop batteries.

A. Materials
Batteries in laptops and notebooks are principally made using either Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH) or Lithium Ion (Li-ion) technologies.
Each type of rechargeable battery technology has its own unique characteristics: Ni-Cd is the earliest battery used in laptop. It has many defects because at the time there wasn't enough technology. It is bulky, heavy. It also has low capacity, short life and memory effect. But now we often use Ni-MH and Li-ion battery. Lithium battery has its strong suit such as small in size, light weight, high capacity, low memory effect, short charge time etc.

People has the wrong concept that Lithium batteries do not have memory effect because they are misled by irresponsible commericals.
Lithium batteries also have memory effect though it is low and inobvious. There are two kinds of lithium battery: li-battery and li-ion battery.

What's different between these two lithium batteries and How to distinguish them?
Li-battery had existed long time before. It is not safe enough and often burns and bursts. Then people have improved and developed li-ion battery.
This technology controlled activity of lithium element and made lithium battery to be more safe, efficient and convenient. As a result Li-battery was withdrawn from the market. The way to distinguish them is to recognize from the marking. Lithium battery used in laptops and mobile phones at present is actually Li-ion battery.

What's Ni-MH battery?
Ni-MH battery is the most environmentally friendly battery. The country that attaches importance to environment often uses this kind of battery because i
