How to Restore the Notebook Battery Discharge Time?

(a) the failure reasons of the battery
The hp HSTNN-DB06 Battery used for a long time, often with charge of electricity, even show the battery has been damaged, specific performance is internal resistance change, in charge at both ends when voltage rise is faster. So easy to charging control line decision for have been filled, capacity and natural decline. Because of battery internal resistance is bigger, discharge voltage decline range, speed, so the system easily mistaken for voltage is not enough, electricity shortage. The discovery of battery work time is short, we should take corresponding measures.
(b) battery refresh program restore the battery discharge time
Brand notebook computer mostly have cell refresh program, using it we can repair to the hp Pavilion DV7 series Battery. For example: notebook computers, with battery is nickel hydrogen (Ni - Mh) battery, due to improper charge and discharge at ordinary times, leading to the battery discharge time more and more short, only less than 5 minutes, if carries notebook computer go out to work, then appears very inconvenience, what method can restore the battery discharge time?
In accordance with the above case, we can use the laptop's official website launched battery refresh program to the battery to refresh, make its restore discharge time, specific methods as follows.
(1) the use of alternating current (ac) to the notebook computer power supply, first of all to the notebook PC's official website to download refresh program.
(2) restart your computer, press F8 key into the boot menu, and select safe DOS mode.
(3) to just downloaded files in directory, perform battery refresh program, read the warning message, according to the requirements insert floppy disk, and then press enter key executive self-extracting operation.
(4) using this floppy disk guide computer, screen appears tooltip.
(5) according to the prompt pulled out ac power supply, and the program will automatically Ni - Mh battery discharge, the discharge is completed, the system will automatically shut off.
(6) with the battery temperature is higher, should not immediately turned on, let the battery cooling after a while, plug in the ac power.
(7) with the floppy disk computer, the file will be run automatically refresh program, and ask the user whether.
(8) at this time, refresh program began to the battery to refresh, its process soon, when back to DOS prompt A: >, said refresh has completed.
(9) off the computer, and to the hp 484170-001 Battery charging, until the indicator light green so far.
(10) above process is repeated three times to get the best effect.
In addition, a lot of lithium battery failure is the battery packs a day to battery core failure, this kind of phenomenon can't avoid. Because each battery battery core properties not be completely consistent, with long some quality after a bit poor start aging, and destroyed the whole (after series of discharge curve. Have interest and ability of readers can try to open the battery pack, the multimeter help, can quickly find damage battery core (abnormal voltage). If the condition allows, according to the corresponding parameters can replace hp HSTNN-LB73 Battery core product.
