Maintain batteries for daily use and maintenance
Maintain batteries for daily use and maintenance
Notebook computer battery is the consumables, the battery once opened, will begin the process of aging. With the aging of the chemical characteristics of cells vary. Aging with the use of normal methods. If the frequent charge-discharge of BATCL50L batteries, it will accelerate the aging batteries. Battery life over a period of time, power will gradually shorten the time until the can not be used. Therefore shorten the battery life is a normal situation. Most of you who normally use an external power supply, like not using the travelmate 290 battery, but a matter of fact, the aging process of the battery over time has been less of the battery can only delay the process, but can not make it stop.
The impact of factors such as battery life:
Battery charge / release number of the use of the environment temperature (30 ℃ suggested that the use of temperatures below computer) battery storage temperature Shock suffered by the size of the BATCL50L4 battery
Battery using must follow the below “principles”
1. AC Adapter (external power adapter) mode, use the battery if it has not gone through charge / discharge process, the life will be longer than the normal battery.
2. A smaller number of charge and discharge a certain extent, can extend aspire one battery life.
3. In the indoor temperature above 35 ℃, the battery wear and tear than the normal speed when the temperature much faster.
4. Throw, hit, etc. batteries will also accelerate Travelmate 290 battery depletion.
Application of the following battery will significantly shorten the working hours.
- The use of CD-ROM drive, such as DVD, CDROM and CDRW drives.
- The use of wireless communications equipment, an external PC card or USB device.
- The use of high-brightness display settings laptop battery, 3D screen savers or other programs, such as 3D games.
- In the highest performance mode of operation of the computer, power management program that is set to “always open” or “Max Battery mode.”
- The activities of procedures, including procedures for running in the background.
- LCD brightness (LCD more light, the greater the power consumption).
