Life with Li-ion Batteries
With the development of science and technology, Mobile computing has become popular in many hands worldwide. Many consumers always hope to get best performance from their battery packs for a long time journey. So through this hub, We are going to find out the ways to conserve the battery
power by learning the practical situation of it. Hope this one would be interesting for every mobile computer users.
What's Li-on Battery?
For many years, portable device manufactures use nickel-cadmium(Ni-Cd) or Lithium-ion(Li-ion) batteries to power-up their products. In the decades of 1970 and 1980, Ni-Cd had been the only suitable battery for portable devices except solar-power panels. They were rejected lithium batteries due to safety problems. Because of the inherent instability of lithium metal. But finally their researches proved that lithium-ion can be used as a better solution to a non-metallic battery that have load characteristics are reasonably good and behave similarly to nickel-cadmium in terms of discharge. Lithium-ion is slightly lower in reactive power than lithium metal. Thus lithium-ion battery cells are safe to store and also meet the provided certain precautions when charging and discharging. Li-Ion battery cell is low in weight and it has a Voltage of 3.6 volts. Thus it allows battery pack designs with only one cell. Most of today's mobile phones run on a single cell Li-ion batteries. A nickel-based pack would require three 1.2 Volt cells connected in series to get 3.6 Volts. Since the first Li-ion battery commercialization from Sony corporation in 1991, most mobile consumer product manufactures use Li-ion batteries for their products to give a better operating duration.
Few important tips to increase battery life of your laptop computer
- Defrag your hard drive once a week.
Defragment makes your hard drive faster. In other words defragment allows the system to catch each file faster. Hard disk contains moving parts that have relatively high power consumption. Thus if its fast, it causes less power consumption. So, make your hard drive as efficient as possible by defragging it.
Goto: Start -> all programs -> accessories -> system tools -> disk defragmenter
(in Mac OS automatically handles fragmentation.)
- Use large RAM
By using large RAM we can decrease the virtual memory usage. Thus it automatically decreases the hard drive usage. No moving parts means less power consumption.
- Do not Standby, Do Hibernate
Standby option is to just turn of your display. But Hibernate totally turns off all parts of your machine without any data loss. It turns off all parts by suspend all our work data to the RAM. No hard disk access. Digitally low power consumption.
To turn on Hibernate option,
Go to: Control Panel -> Power Options
- Do not leave fully charged Li-Ion battery
If you fully charged your battery you have to use it at least 5 minutes.
- Let it drain at least to 13% once a week. (Causes dead cells)
- Do not let it completely discharge (Specially for Li-Ion batteries)
- Keep Battery connectors clean
Remove the battery and clean the connectors with a dry cloth. This keeps the transfer of power from your battery more efficient.
- Adjust your LCD screen brightness to lower value
