The Laptop is the wonderful creation of science. Before the Laptop was the desktop computer and Laptop has replaced it.
The main reason is because of its wireless features, which are available because
of Laptop batteries. Laptops can be carried anywhere because of its wireless features
and batteries help make this possible, so they are essential in a Laptop.
Laptops use too much battery power from its battery capacity. This happens
because these batteries must be small and lightweight so that they can be easily
fitted in the laptop. Normally laptop battery last for ninety minutes. This is a
major problem because laptops are meant to provide service even on the road or
when moving. Using heavier and larger sized batteries can solve this problem.
One more factor that affects the performance of a battery is the temperature
inside the laptop. As temperature goes high laptop has to turn on its processor
fan to bring temperature to normal. Battery loses half of its power when working
because of the temperature in the laptop that can reach the 45°C mark. This
happens because of the cell oxidation that takes place inside the battery. Cell
oxidation is an irreversible process that is detrimental to the lifespan of a
laptop battery.
Lithium ion batteries are well suited for those who switch from a fixed power source to a battery on a regular basis. On the other hand, nickel based batteries are useful for those who prefer using the battery as a primary source for the laptop.
And now laptop battery can last up to 40 hours, yes research at Stanford Tech to develop hi-tech lithium ion battery for long life working. The new battery uses a advance technology – silicon anodes in the form of nanowires for charging. This technology was earlier abandoned as the silicon expands up to 400 times when charged, exploding the battery in the process. Using silicon in the form of nanowires eliminates this danger.
Three Kinds of Laptop Batteries :-
- Nickel Cadmium
batteries
- Nickel Metal
Hydride batteries
- Lithium Ion
batteries
Among the 3 kinds of batteries, the
Lithium Ion is the one used in the latest Laptop models. Although the most expensive
but it is the most efficient, reliable and lighter too.
Following are Precautionary Measures
to Save Laptop Batteries:-
- Laptop batteries
should be charged only when they fall below 80% in its capacity.
- While charging
the battery, the Laptop should be turned off when possible. If kept on, the batteries
won't acquire the required charging power.
- Leaving a Laptop
in a car that is parked in the sun will result in battery damage so this situation
must be avoided.
- Using the Laptop
in a cool room will result in increase in the lifespan of the battery.
The mobility of Laptop depends heavily
on the batteries. Spare Laptop batteries enable people to work for long hours on
flights or in remote places where power connections are either unavailable or hard
to come by.
When one buys a laptop, buying a spare battery also makes lot of sense because Laptops
use much battery power when hard drives and CD drives etc are used. Mostly when
we work on laptops, we listen to songs etc, use hard disks to access large files
and so the battery usage is far more so spare batteries are very useful and also
not so expensive.
Laptop batteries are very important
accessory and must be bought after due care and research
