Understanding Batteries

Battery Type:

Nickel-cadmium (NiCd): This is the first rechargeable batteries manufactured for laptops. They are relatively inexpensive, high performance and versatile because it can be used in a wide range of products. However, NiCd batteries have now been abandoned by laptop manufacturers with the introduction of more efficient battery and lighter.

Nickel Metal Hydride (NiMH) Batteries: NiMH was a big improvement in terms of power, reliability, cost, safety and capacity. The “memory effect” is the only issue with NiMH batteries that require them to be fully discharged before recharging for maximum efficiency. These batteries can still be found on older model laptops.

Lithium Ion (Lion): This type of laptop battery has become the most popular of the “memory effect” has been removed, and the weight is much lighter than the other two. However, market prices are also higher.

Cycle Battery:

A battery cycle is used every time the battery is charged or discharged. Technically, it is defined as the number of cycles a battery that can be made before the nominal capacity of less than 80% of the initial rated capacity. The life cycle of a typical 500-1200. For example, nickel-cadmium batteries have a life cycle 500-1000 or more cycles.

Battery:

Battery life depends on a number of factors. Most of the time, it is the design, and the demand for power is radiated by the device that determines the actual battery run time. For example, the use of screens, hard drives and other accessories will significantly affect the duration of the execution.

What a smart battery and Stupid:

Some laptop batteries are equipped with internal microprocessor circuits that help manage battery energy, set the charger to the correct charge algorithm, predict the duration, or the Smart Battery System (SBS) forum, provide state of charge (SoC) indication. These batteries are called “smart” batteries. These batteries are labeled “stupid” does not have these characteristics, it might be colleagues, and operated to provide electricity only.

Battery Optimization:

1. “Condition” is a term for fully charging and discharging a new laptop battery to maximize performance and allow it to reach its maximum rated capacity. NiMH and NiCd batteries should be conditioned at least once a month to reduce the “memory effect”.

2. Metal connectors should be cleaned occasionally to maintain good conductivity

3. Make sure the power management functions of the device in the BIOS and the operating system is optimized, off-screen, with step speed

4. Do not leave your laptop on overnight all the time while charging. Notebook must be switched off from time to time.

5. Store batteries in a cool, dry and clean, even if you do not use it for a month or more.

6. Lower the brightness of the LCD screen when you’re watching a movie on our laptop. Decrypt DVD movie and save it on your hard drive to avoid the constant use of a DVD player that consumes a lot of energy

7. Do not expose the battery from your laptop to heat, moisture short circuit, fall or physically abused.
