Dell's official website: battery for daily use maintenance and repair work

laptop battery is consumables, batteries, once the Kaifeng to use, will begin the aging process. With the aging rate of the chemical characteristics of the battery varies. Aging rate with the use of usual methods. If the frequency of Sony VGP-BPS9 battery charge and discharge, it will accelerate the aging batteries. Battery in use for over a period of time, power will gradually shorten the time until it can not be used. Therefore, the shortening of battery life is a normal situation. Although usually you mostly use an external power supply, as if not using batteries, but in fact, the Sony VGP-BPS8 battery's aging process as time goes on, has been engaged in, use less battery can only slow down the process, they can not make it stop
Factors that affect DELL XPS M1530 Battery life
* Battery charge / discharge times
* Use the environment temperature (recommended temperature below 30 ℃ using computers)
* Battery storage temperature
* The size of the battery suffered a shock
The battery used in several "principles"
1. In AC Adapter (external power adapter) mode, use the battery if it has not gone through charge / discharge process, the battery life will be longer than normal use.
2. Less charge and discharge times can extend the DELL XPS M1730 Battery life to a certain extent.
3. In the indoor temperature reaches above 35 ℃, the battery consumption rate of use than the normal temperature much faster.
4. Threw the collision cell such acts will also accelerate battery depletion.
The following applications will significantly shorten the battery's working time
1. Using the CD-ROM drive, such as DVD, CDROM and CDRW drives.
2. The use of wireless communication devices, external PC Card or USB device.
3. The use of high-brightness display settings, 3D screen saver or other large programs, such as 3D gaming
4. At the highest performance mode computer power management program that is set to "always open" or "Max Battery mode."
5. The activities of procedures, including the background running programs.
6. LCD brightness (LCD more light, the greater the power).
