To show the battery is damaged


To show the battery is damaged. Therefore, the maintenance and rehabilitation needs of dell laptop battery users is the topic of concern. Maintenance process is also often referred to as “activation”, “activation”, a very vivid and to reflect that the acer laptop battery “dead” and rebirth process.

I summed up the activation of a approach, its basic principle is that when the laptop battery charge and discharge currents must be small (but not too small, or too long), there is to try to be filled, put completely. Cell damage because the battery in use after a period of time will “aging” of. Concrete expression of the resistance is bigger, at charging time at both ends of voltage rise faster, so it will be easily found for the charge control circuit has been filled, the capacity also is naturally “down”. Since relatively large dell 4834T battery internal resistance, discharge voltage drop by high speed, the system can easily mistaken for a voltage not enough, lack of electricity (in fact, there is no electrical discharge).

As can be seen from the above description of the battery is a vicious cycle of aging process, the discovery of lost working hours, the battery faster than when what it should be tempered, or else it will be finished sooner or later. In addition, many lithium battery failure is the dell 2834T battery package of a certain energy-saving result of core failure, a bad pot of soup mouse droppings. This phenomenon can not be avoided, because the battery power-saving core of each character can not be fully consistent with a long time there are some quality, the aging first weakened, undermining the whole (series after) the discharge curve. It simply means that section of bad dell Latitude LS battery before charging full discharge also finished first place, but this time the capacity of the other batteries have not been fully utilized.

The core of a power-saving over charge / over-discharge will not cause the battery monitoring circuit that the whole is full of / discharge end of the. For example, when charging other batteries start getting close to full charge when pressed, that section of bad batteries may have reached the terminal voltage of 4.30V or higher, resulting in overcharge damage, while others are sufficient dissatisfaction. Editor’s note: For internal batteries battery damage, the “Chinese computer education” 2001 No. 2 has a very good article - “notebook computer batteries DIY” worth learning from. Interest, courage and capacity of friends can try to open the dell Inspiron 2000 battery pack, believe that the help of multimeter, you can quickly find the damaged batteries (voltage abnormality). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product. The battery charge and discharge lithium-ion battery charging poses as a way of fast charge constant current in the voltage reaches a certain value and then to slow charging constant voltage mode. Notebook computers are often not strictly a constant-current charge of monitoring devices dell W0465 battery.

The system load when a large charge current on small, whereas the large, the current from the AC power adapter power margin decision. Clearly, the system will charge the battery and other components, such as CPU, hard drive, LCD and other competing energy sources. I tried to run side Superπ, while charging the way and found that the charge current in the 0.70 ~ 1.70A between the changes, can not meet the lithium-ion dell Latitude X300 battery charging requirements, so I fear that this will work, rechargeable batteries were defective. IBM statement calling for notebook computers will not operate when the charge is probably the reason. Charge at boot time, if we can select the charge mode, you do not choose fast charge mode (Express charge mode), to avoid premature battery “full.”

There is a time of low dell BAT3151L8 battery power to prohibit the use of the highest CPU performance in order to reduce the power of the competition. If the notebook computer’s CPU is to support the use of SpeedStep technology, it is best to install the driver (the vendor will be responsible installed) to facilitate the adjustment performance. SpeedStep program icon is a blue flags, right-click performance tuning options it can occur. Under the Windows XP system, SpeedStep program will be problems, this time to rely on or to modify the BIOS parameters of the regulation of a number of brand-specific programs, such as IBM notebook computer software is very powerful tool.

Electric-discharge of lithium, or always-on, let the natural discharge better dell 1G222 battery. Is best not to use physical methods (string of resistors in the class). Not to say that that was not feasible, but relatively large risk, if the internal protection circuit was not working, then set aside the batteries, and the worst is probably the battery explosion, of course, this unlikely. Circuit hidden dangerous is not impossible, a number of big-name manufacturers have found that the design of potential risk factors exist in a battery recall, as mobile phone battery when you do not hear the explosion.

Small knowledge:

In general, notebook computer dell INSPIRON 2650 battery protection circuit in the part is usually voltage block, control chip, insurance, and temperature probes. Temperature protection device is usually a one-off, the inside has a fuse (some 130 ℃ Fuse), is used to monitor the voltage regulator block work. If the charge-discharge process exceptions, immediately there will be a current through the temperature protection device, will fuse fuse, the battery’s internal circuitry at this time for the open circuit state, and can not be restored. If you want to repair only the replacement of temperature protection device, but such temperature protection device on the market hard to find. Discharge is the discharge current as small as possible, the operation is to slow down and let the CPU, hard disk stops turn, transferred the darkest the screen (or close the switch off), then do not run any programs until the laptop automatically shut down. The emphasis on small-current discharge is to prevent premature detection of laptop battery shortage. I have disabled the hard disk, close the screen, cancel the power of the state police under the laptop completely discharge (put a close to 6 hours), the dell INSPIRON 2600 battery capacity from 31.72Wh restored to 33.65Wh.
