                            Laptop battery tips

Laptop battery in use after a period of time will be aging, the specific performance of the larger internal resistance, both ends of the voltage when charging up faster, so it is easy to charge control circuit is judged to have been filled, the capacity is naturally decreased It's For mobile devices, the battery can not last longer certainly be very worried, and some users bought second-hand laptop or even simply can not use the battery, this time to upgrade the battery repair is very necessary.

The first one: please discharge "experts"

As the battery resistance is relatively large, the discharge voltage drop, the speed is fast, the system is easily mistaken for the voltage is not enough, resulting in power shortage, but in fact there is no electric discharge, and usually the battery is a vicious cycle of aging The process of voltage drop out faster when the battery is found, then we should exercise it, or sooner or later will be finished.

Battery calibration is an effective way to deal with battery aging, in general, each brand of notebook will have a dedicated battery calibration software.

Discharging prompts unplug the AC power, the discharge of the software will automatically discharge control. When everything is over notebook will automatically shut down, and then we can connect AC power for charging, time control in 9 to 12 hours, repeated 2 or 3 times. Laptop battery calibration, the key is to find a suitable discharge software. However, if your notebook does not have a dedicated discharge software, then you can follow the steps below:

★ Disable screen saver

★ In Windows Power Management, set the power usage plan to "Always on"

★ in the alarm tab will be "low battery warning" to remove the hook, the operation is set to "no operation"

★ Remove the alarm before setting "Alarm for severe shortage of electricity" and operate as "Wait" (Figure 2)

★ the brightness of the screen to the highest

★ Confirm that all the windows are closed, and save all data of previous work

★ Make sure the battery charge is over 80%, unplug the power and all external devices

The battery will be aging after using for a period of time, the concrete manifestation is that the internal resistance becomes larger, the voltage at both ends of the battery rises rapidly when charging, so that it is easy to be judged by the charging control circuit to be full and the capacity naturally decreases . For mobile devices, the battery can not last longer certainly be very worried, and some users bought second-hand laptop or even simply can not use the battery, this time to upgrade the battery repair is very necessary.

After the above operation so that the notebook naturally discharge to automatically shut down (this process may be longer), and then plug in the laptop charging, this process can be repeated 2 or 3 times. In fact, the purpose of this approach is to allow the battery to continue to discharge a small current, and this state of discharge in our daily use is impossible to achieve, the effect and those dedicated discharge software is basically the same.

The second measure: choose the best timing of repair

Deep charge and discharge operations for notebook batteries and no good, this is a last resort approach. If the battery life only reduced by tens of minutes, then you should be cautious to take this method of operation. In addition, the manufacturer has optimized the battery, there is no self-depth charge and discharge can once again enhance the battery capacity of the argument.

The third measure: DIY batteries for the core

When the laptop battery completely unusable, we simply do not need to replace the entire panel. In fact, the laptop battery can be divided into two parts of the circuit board and lithium battery batteries, of which the former is a very small probability of damage, most of the scrapped laptop batteries can be upgraded to lithium batteries batteries to revive.

Laptop battery bonding technology varies, some older batteries are used to clamp the screw, a little better with ultrasonic welding of the battery, the glue is generally used to glue the upper and lower lid, this time can be carefully observed, take a look at the battery What are the gaps on the block, consider what gap should be prized open with a blade and a screwdriver. Disassembly can be used electric knife or blade along the battery cover at the junction of the slit into and around the slit for a week, and then use a screwdriver into the side of the slit pry open the battery box, pay attention not to force too much, or may be Damage the battery compartment or the internal circuit board (Figure 4). Disassemble the shell, you can see the internal lithium batteries, usually 4 ~ 8 batteries with a series of parallel mixed composition, it is recommended to try to buy the same voltage and the number of batteries, but do not change the connection to upgrade. Upgrading laptop battery batteries may require a certain electrician basis, demolition of the original cell must be very careful, do not damage the surrounding circuit boards, and to reserve a certain length of the connection film. In addition, most lithium battery cells are chrome-plated on the housing, which may cause great inconvenience to the tin.

        Tip: it is best to test before using the voltage to meet the requirements, appropriate 2 to 3 times the depth of charge and discharge. In the case of increased battery capacity, sometimes the laptopbattery circuit board will not be able to identify the internal battery in the beginning, resulting in false positives, but as long as the deep charge and discharge to maintain 2 to 3 times, this situation will be greatly improved
