After some time, the battery will be aging. Specific expression of the
resistance, when both ends of the charging voltage rises faster, so it
is easy to be charging control circuit is judged to have full capacity
of nature is "down". Relatively large due to the internal resistance of
the battery, the battery in use after a period of time will be aging.
Specific expression of the resistance, when both ends of the charging
voltage rises faster, so it is easy to charge control circuit is judged
to have full capacity natural decline. The relatively large battery
internal resistance, discharge voltage drop, the speed, the system is
easily mistaken for a voltage is not enough, the lack of electricity (in
fact, there is no electrical discharge). Can be seen from the above
description of the process of aging of the Asus K72J battery
is a vicious circle, found faster battery working time off when they
should exercise it, otherwise, sooner or later, will be finished.
Battery charge and discharge:
The first constant current lithium-ion Asus K52J Battery
charging, fast charging, the voltage reaches a certain value and then
to constant voltage trickle charging. Laptops usually are not strictly
constant-current charge monitoring device. Large load on the system when
the charging current is small, whereas the large, the current from the
AC power adapter power margin. Obviously, the system will charge the
battery and other components, such as CUP, hard drive, LCD and other
competing energy sources. I tried to run side to side charging and found
that the charge current varies between 0.70 ~ 1.70A, can not meet the
requirements of the charging of the lithium-ion battery, so I worry
about this work when charging the battery will have damage. Do not
operate the IBM statement on the request of the laptop charging is
probably the reason.
When you start charging, if we can select
the charge mode, do not select the fast charge mode (Express charge
mode), avoid premature battery fully charged. There is a low battery
prohibit the use of CUP's highest performance, in order to reduce
competition for power. Laptop CUP support SpeedStep technology, it is
best to install the driver (responsible vendors will be installed) to
facilitate the adjustment performance. SpeedStep program icon is a blue
flag, right-click on it to performance tuning options. Windows XP
system, SpeedStep program will be problems, this time to rely on to
adjust the program to modify the BIOS parameters or some brand dedicated
software tools such as IBM laptop is very powerful.
On the the
lithium discharge or always-on, let the natural discharge better. It is
best not to use physical methods (string resistors and the like). Not to
say that this is not the only risk is relatively large, the internal
protection circuit did not work, the entire battery void the worst
possible battery explosion, of course, this is unlikely. Circuit hidden
danger is not possible, some of the big manufacturers have discovered
the potential risk factors in the design and recycled through Asus A32-N61 Battery As for the mobile phone battery explosion is not heard.
Small knowledge: In general, the Asus A32-K52 battery
protection circuit parts are usually the voltage regulator block,
control chip, insurance, and temperature probe. Temperature protection
is usually a one-time internal fuse (some 130 ℃ fuse), used to monitor
the voltage regulator block work. If the charging and discharging
process, and immediately there will be a current temperature protection,
the fuse blows, the battery inside the circuit for the off state, and
unrecoverable. If you want to fix the only replacement temperature
protection, but these shall only be such as temperature protection is
difficult to find in the market.
Discharge is to try small
current discharge, the operation is let CUP spin-down, hard disk stall,
the screen tune darkest (or close off), and then do not run any programs
until the laptop automatically shut down. The emphasis on low current
discharge is to prevent the laptop premature detect the Asus K52F battery voltage is low.
