Acer AS09A41 battery internal resistance is big, the battery after using for a long time will be aging. Specific performance is internal resistance, at the time of charging voltage on both ends to rise faster, it'll be easier to determine by charging control circuit has been full of, nature is "down" capacity. Because the Acer AS09A41 battery internal resistance is big, when the discharge voltage drop, quick speed, can easily be mistaken for voltage is not enough, lack of electricity (there are electric put out). Can be seen from the above description of the battery aging is the process of a vicious cycle, the discovery of the battery work time off faster when they should practise it, otherwise, sooner or later.
Battery charging and discharging:
When
Acer AS09A41 battery first quick charge in the form of constant current, the voltage reaches a certain value in constant pressure way slowly again after charging. Usually a laptop is not strictly constant current charging monitoring device. System load the charging current is small, on the other hand is big, the current is determined by the power of the AC power adapter allowance. Obviously, the system will charge when the battery and other components, such as CPU, hard disk, such as LCD scrambling for energy. I tried running Super PI, while charging way, found that the charging current is between 0.70 ~ 1.70 A change, can't satisfy the requirement of the lithium ion battery charging, so I worry will this work when charging the battery is damaged. Acer requirements on the manual for charging laptops don’t operate are likely to be the truth.
In the boot when charging, if can choose charging way, don't choose quick charge mode (Express charge mode), avoid premature battery "full". There is highest when the battery is low to ban the use of CPU performance, in order to reduce competition for power. If used laptop CPU support Speed Step technology, best to install the driver (responsible vendor will install) to facilitate regulation performance. Speed Step program icon is a picture of a blue flag, right click on it can be adjusted to performance options. Under Windows XP, the Speed Step program will be a problem, this time can only rely on modifying the BIOS parameters or some brand dedicated to adjust program, such as IBM laptop tool software function is very powerful.
For li-ion battery discharge or has been switched on, make its natural discharge. It is best not to use the method of physical (series resistance). Not to say that no, risk is relatively large, if internal protection circuit doesn't work, the whole battery is invalid, the worst may be battery explosion, of course, this possibility is very small. Circuit hidden danger is not not possible, on some big manufacturers have found that design of potential dangerous factors and recycling batteries, as for mobile phone battery explosion was heard from time to time.
Little knowledge: in general parts in
Acer AS09A41 battery protection circuit are usually a voltage regulator, control chips, insurance, temperature probe, etc. Temperature protector is usually a one-off, internal have a fuse (some of them are 130 ℃ fusing), used to monitor the pressure regulating piece of work. If abnormal charge and discharge process, immediately there will be a current through the temperature protector, the blown fuse, inside the battery circuit for open circuit state at this time, and is not recoverable. If you want to repair only replace temperature protector, but such temperature protector is hard to find in the market.
Discharge is small current discharge, as far as possible action is to let CPU speed down, hard disk, screen the darkest close (or off), then don't run any application, until the laptop computer automatic shutdown. Is emphasis on small current discharge in order to prevent laptop early detect the battery voltage is insufficient.
