How to charge notebook battery?

We should start from the material of the battery. The battery of the notebook computer can mainly divided into three kinds at present. That is 1.Nickel chromium battery, 2. Nickel hydrogen battery, 3. Lithium battery; They are generally expressed as: Nickel cadmium NICD, nickel hydrogen NIMH, lithium Li.

During the last few years, batteries have improved in terms of energy density.But any benefit in better battery performance is being eaten up by the higher power requirements of the laptops. This trend is continuing and the net effect will be the same runtimes but more powerful laptops.

Most laptops are powered by lithium-ion. This chemistry has a high energy density and is lightweight. There is no immediate breakthrough on the horizon of a miracle battery that would provide more power than the current electro chemical battery.

Fuel cells, when available, will offer a continued stream of power by allowing the exchange of fuel cartridges when empty. Unfortunately, commercial fuel cells for laptops and other portable devices are still several years away.Power handling, size and cost remain the biggest hurdles. The early fuel cells will function more like a portable charger than a battery replacement. The fuel cells currently in use have the difficulty in providing spontaneous high power on demand.

The runtime of a laptop battery is based on the activity of the computer. The basic housekeeping, which the computer needs to stay alive, draws less power than, for example, reading, writing, computations and searching for files.Manufacturers prefer using idle time when specifying runtime.
