Understanding mobile “Batteries”

Types of portable batteries: Nickel cadmium (NiCd) batteries: they were the first rechargeable batteries, which are made for laptops. Have been relatively good market, high production and universal, because they cannot be used in a wide range of products. However, batteries NiCd abandoned now producers of portable computers with the introduction of more efficient and a thinner battery.

Nickel metal hydride (NiMH) battery: NiMH was significantly better performance, reliability, cost, safety and capacity. “Memory effect” was the only problem with NiMH batteries requiring completely before recharging for maximum performance. These batteries are located in the older models of laptops.

Lithium-Ion (Lion): this type of battery has become the most popular laptops, because that “memory effect” has been removed and lighter than the other two weights. Market, however, is also the highest.

Battery cycle: a cycle of the battery is used whenever the battery is loaded or unloaded. Technically speaking, is defined as the number of cycles the battery that you can do prior to its nominal capacity less than 80% of their original rated capacity. Life cycles of 500 to 1200 are typical. NiCad battery has a life cycle, for example, between 500 and 1000 or more cycles.

Battery type: battery run time runtime depends on a number of factors. Most of the time, the proposal and the requirements of the power of your computer, that determines the actual battery runtime. Use the screen, the hard disk and other accessories such as significantly affect running.

The smart and Dumb some portable batteries: batteries for portable computers are equipped with an internal microprocessor circuits that helps manage battery chargers, set the correct load algorithm to predict the duration of operation, or smart battery (SBS) Forum system, indicates the State of charge (SoC). These batteries are called ‘Smart’ battery. These batteries are designated as “dumb” have not these features, might be only homologous or can function to provide the performance only.

Optimization of portable batteries: 1. “State” is a term for a battery completely new loading and unloading of the laptop to maximize performance and allow the maximum realization of its nominal volume. NiMH and NiCd batteries you need to reduce ‘memory effect’ conditioned at least once a month.

2 Move them metal should occasionally clean to maintain good conductivity 3. Ensure that the capabilities of device in the BIOS and the operating system power management are optimized, turning, speed, step 4. Your laptop always night when it loads. Laptop computer must be turned off on occasion.

5 except fresh, dry and clean battery place, you can use for a month or more.

6 the brightness of the LCD display are erased when watching a movie on our laptop. Decrypt DVD movies and save to your hard disk with constant, use not DVD-ROM, which consumes energy of 7. Never expose the laptop battery to heat, moisture, short-circuit, drop or physically abuse.
