If you have a laptop, the odds are high that it is powered by lithium-ion (Li-Ion). This kind of battery has been used in a variety of consumer electronics such as PDAs and cell phones.
They are the dominant type of rechargeable batteries in laptops today because they're smaller than other types of laptop batteries and they last longer than other technologies and also because they do not suffer from the memory effect phenomenon. Type lithium ion battery is more energy than a typical nickel Cadmium Apple MacBook professional 17-inch battery.
The Batteries Lithium-Ion computers also require protection circuits that are incorporated inside the battery to monitor the battery's voltage and provide the secure and current level and ensure that the Apple A1185 battery's temperature is within the safest range for operating.
LithiumIon batteries are typically cylindrical in form, and somewhat like normal notebook batteries. A number of cells are contained in a plastic case, and the cells are connected in a way that allows for the correct output voltage and the highest capacity of storage (rated as milliamp hours).
The Lithium-Ion prismatic form is also available, however, they are significantly smaller and are usually used in mobile phones, where weight and space are the primary concern.
Lithium-Ion batteries are not as long-lasting because they are older technology batteries; however, they are independent of their charge cycles and are mostly dependent on their age. The typical battery will last 3 to 5 years.
