"The more lithium battery put the discharge to make, the greater will be the loss of the battery," Yike Lang University, to help the U.S. space agency NASA to extend the battery life of electronic engineering professor Tom Hartley, said, "to charge the battery full charge and the more , the battery consumption will be greater. lithium battery is in the middle of the best state, so if battery life.

First, the high and low power state of the lithium battery life of the most adversely affected, and charge-discharge cycles but is secondary. In fact, most of the sale of electrical or battery can be recharged on the identification number, are to discharge 80 percent obtained for the benchmark. Experiments show that, for some notebook computer lithium battery, always let the battery voltage exceeds the standard voltage of 0.1 volts, which rose from 4.1 volts to 4.2 volts, then the battery life will be halved, and then increase 0.1 volts, the life expectancy reduced to the original 3 one; long-term low battery or no battery power of the state of the internal electronics will move more and more resistance, thus leading to smaller battery capacity. NASA NASA Hubble Space Telescope allowed the consumption of battery power on the set at 10 per cent of total capacity, to ensure that the battery charge and discharge can be repeated 10 million times without having to update.Acer Aspire 1680 Series AC Adapter   Acer Aspire 3000 AC Adapter   Acer Aspire 3500 Series AC Adapter

Secondly, the temperature on the lithium battery has a greater influence life (cell phones and other small electronic devices can be ignored on this point). Below freezing environment has the potential to open lithium batteries in electronic products, burned the moment, but excessive heat will reduce the battery capacity. Therefore, if the laptop is not the long-term use of an external power supply will take off the battery, notebook battery discharged to a long period of high fever which, more importantly, long battery charge status is 100 percent, will soon be scrapped (including me your laptop battery is so comes to an end of.)

From the above, we can conclude the following points to ensure the lithium battery capacity and life of note:ASUS Eee PC Battery Sony VGP-BPS8 Battery

 No need to charge to 100 percent lithium battery fully charged, will power not to use depleted. Where conditions permit, as far as the battery to maintain state in the vicinity of half full, charge and discharge rate as small as possible;
GM Chevy Volt electric car factory design is to force the battery to maintain 20% to 80%, while Apple notebook built-in battery may also use this method (including a number of notebooks and other electronic products), so that the battery charge and discharge cycles can be increased.

Do not lithium battery (especially lithium laptop battery) Long-term use of an external power supply in case of equipment to work. Even if your laptop heat dissipation, long-term is equal to 100 percent of electricity to the murder of lithium batteries.
