Some time ago APPLE, SONY, DELL, HP and other international well-known PC giants have emerged in the notebook battery recall problems and the original?
hp laptop battery Today I would like to extend the topic to a number of laptop battery knowledge to share with you?
Why do books The more you use the battery Dell inspiron 9200 battery power consumption less? Why do battery calibration feature makes capacity to restore part? How is the correct
battery charger? All this from the start with the calculation of battery power … …

Whether it has been eliminated nickel-metal hydride batteries, now used in lithium-ion battery, or not commonly lithium polymer batteries, or even tomorrow’s stars of the silver-zinc batteries( sony vgp-bps5a battery
), are the equivalent of a warehouse storing electricity, the difference is that they access library approach, the storage capacity only. In the notebook computer batteries, as well as a large responsible for managing these batteries housekeeper – power computing chips, which is the management of battery, computing power, is responsible for charging and discharging of the “responsible person.”
In the measurement of battery technology, there are four kinds of common method,F2299A Battery, F3172A Battery, Pavilion ZT1000 Battery, Pavilion XZ200 Battery, but not books of different brands of batteries using only one method of calculating dell latitude c600 battery dell inspiron 1720 battery power consumption are usually several ways to use an integrated, in one of the main method of calculating The remaining auxiliary calculation means to achieve the computing power to manage.), are the equivalent of a warehouse storing electricity, the difference is that they access library approach, the storage capacity only. In the notebook computer batteries, as well as a large responsible for managing these batteries housekeeper – power computing chips, which is the management of battery, computing power, is responsible for charging and discharging of the “responsible person.”
The first is the open circuit voltage measurement method, F2299A Battery this method is by measuring the battery voltage in the stationary state values to calculate the remaining battery capacity, but because of stationary lithium-ion battery voltage and remaining capacity of the relationship between the non-linear, Therefore, this method is not an accurate measurement of the value of the vast majority of cell phone batteries have adopted this method of calculation; the second is called Coulomb’s method of calculation, the method is by measuring the battery charge and discharge current, the current value and time value of the After the product is calculated by integrating the batteries into the battery charge and the release of electricity, Coulomb’s method of calculation is a more accurate method of calculating Acer aspire 5920 laptop battery power; third is to impedance measurement method, it is by measuring the resistance within the battery get the battery remaining capacity value; The fourth is a comprehensive look-up table method, by setting a related table, the voltage, current, temperature and other parameters input, you can check the battery’s remaining capacity to be.
Thus, apart from the internal structure of the battery batteries, there are management chip, the chip contains one or two of them measuring method ofcalculating capacity batteries, and a set of charge and discharge protection circuit. Among the notebooks in the system, through the driver interface access to this chip, and then set the battery management.
So, why the battery would be more you use less electricity, but the implementation of the correction function can restore the battery capacity of a part of it?
Laptop batteries Dell 5160 battery Dell inspiron 640m battery are generally the so-called six-pin power, 4-pin power, refers to the number of battery cells within the batteries. So many batteries together, F3172A Battery that is, the less electricity more you use the fundamental reasons: batteries and the batteries between the quality of discharge can not be exactly the same level, such as discharge, in which a substantial reduction in power batteries, In order to maintain voltage stability, battery management chip will follow “casks principle”, according to the worst of that energy-saving core to charge protection, battery charge will naturally decline, the impact is even more than the battery irreversible Institute of Chemical Physics change.
Battery calibration function is to balance the multiple batteries, the battery because of their resistance can not be completely consistent, the battery will be great resistance bear strong current, F2299A Battery, F3172A Battery, Pavilion ZT1000 Battery, Pavilion XZ200 Battery,leading to their own consumption more than other batteries, but also easier to wear and tear, therefore, on a regular basis to do the battery calibration is necessary – so as to balance the burden of multi-cell “work”, thus extending the overall life expectancy.
The impact of laptop battery life factors, battery life did not meet expectations for the use of laptop computers, some factors that make battery depletion, and they may even lead to the longest battery time is below standard, but does not mean that these factors may damage the battery . Impact on battery life factors:
factor1: processor speed – the right to install Intel chipset driver will enable the system to use Intel Speed step technology for the processor speed of
adjustment, Pavilion ZT1000 Battery which will be extended in the application of the system batterydell latitude d830 battery life.
Factor 2: CD, DVD, CD-RW and hard drive frequently read – trying to CD-ROM copy of the document to your hard disk directly in operations (including copy, delete, and run an application, etc.) will increase the battery life.Factor 4: a number of applications to run automatically in the background when the CPU load will increase, resulting in reduced use of time – the proposed use will be some normal background running programs closed, only necessary to run application software.
Factor 5: LCD’s brightness – set the brightness of the lower battery life for the better length of time, you can use FN + function key to use to adjust brightness.
Factor 6: Speed Step power management and set up – set up power management in a different power scheme will affect battery life.
Factors 7: battery life – the average laptop battery life is one year, Pavilion XZ200 Battery with the use of time and increase in the number of batteries to
reduce the use of time is normal.
Factor 8: processor and system equipment for the deeper applications (such as watching DVD movies and 3D games) the battery will quickly reduce the
available time.
Factor 9: wireless devices and the Bluetooth device will speed up the dell d620 battery ( dell d630 battery )consumption;F2299A Battery, F3172A Battery, Pavilion
ZT1000 Battery, Pavilion XZ200 Battery, the need for wireless can be shut down to save power.
factor 10: the use of the environment temperature – too high or too low use of the ambient temperature will affect toshiba satellite a10 battery in the activity of chemical substances, thus reducing the use of battery time and life.
