    There is a saying that if your rechargeable batteries used properly, will appear a certain cycle range of the best state, which is the largest capacity. This should be sub-situation, sealed nickel-metal hydride batteries and nickel-cadmium batteries, if used properly (such as regular maintenance to prevent the memory effect generation and cumulative), generally in the 100 – 200 cycles to reach its maximum capacity, such as factory capacity 1000mAh Ni-MH battery with 120 cycles, its capacity could reach 1100mAh. Almost all Japanese Ni-MH battery manufacturer’s technical specifications book describes the cycle characteristics of nickel-based batteries as this description.

    Nickel-based batteries have the best state, typically 100 – 200 between cycles reach their maximum capacity.

    For liquid lithium-ion batteries, there is no such cycle capacity hump phenomenon, from the lithium-ion battery factory to the final retirement date, the performance of its capacity is to use a less time after you use. When I do in the cycle performance of lithium-ion batteries, there has never seen signs of recovery capacity.

    Lithium-ion battery has no best condition

    It is worth mentioning that the lithium-ion battery is more susceptible to environmental temperature and changes in different properties, in 25 – 40 degrees ambient temperature will show their best performance, while the low temperature or high temperature condition, his performance is significantly impaired. To get your lithium-ion batteries fully demonstrated its capacity, must be careful attention to the using environment, to prevent the high and low temperature phenomena, such as mobile phone on the car before the stage, direct sun at noon is very easy to make it more than 60 degrees, the North users’ battery standby time, in the same network circumstances, is less longer than the South users.

    1. When the battery is charged , we can look at the machine shows battery useing time and whether it is the same as the sueing time in the instructions marked , full power later time after the show  should be close to the first time , if it is shorter than the standard time ,then the battery is false.
    2. when Use the battery,the machine shows the battery has some time but the machine automatically shut down because of lack of power, and this phenomenon has always existed, then this probably is the counterfeit lithium battery.
    3. Fake battery is lower than the true time of normal use the battery, the first may be little difference, but as the use of time, would leave more poor battery performance, use less and less time .
    4. the false battery sometimes will show the battery has run out, but can also shows use the phenomenon of long time, but when the true battery is exhausted ,the battery power generally display will automatically shut down soon.

    Why is the laptop battery power also reduced when it is not used ?

    As impact of the environmental humidity and the non-absolute insulation enviroment,the battery exists natural consumption phenomena , depending on the recency and quality of the batteries, 3-4-days will dro of about 1%, so long as not a significant decline in all is normal.

    1 Q: My laptop uses the AC when in the case of with the battery , the task bar shows it is charging. Will the power come from the notebook battery or AC power? When the battery is full 100%, then the task bar shows the use of alternating current. Will this time using a laptop on battery power or AC power?

    A: When your laptop use with the battery , the notebook’s power entirely from the AC. When the battery is full 100%, as long as the task bar shows the use of alternating current, then the laptop will stop charging at this time, and fully use the AC power supply. Need to remind you that if you do not use the battery for a long time, it is recommended to remove the battery, which is good to extend the life. Do not frequently charge the battery on the laptop because the lithium-ion battery also has the life limit

    (1) lower the screen brightness. How to adjust the the laptop brightness when using the battery, start by F2, into the BIOS to adjust the Brightness Video items.
    Or use the fn + down / up key combinations quickly adjust brightness.

    Old BIOS details, please refer to:
    http://support1.ap.dell.com/cn/zh/forum/thread.asp?fid=25&tid=45151

    (2) Open the CPU speedstep function, you can greatly extend the battery life; Cpu’s speedstep  function in the BIOS is enabled by default. When using batteries, cpu frequency used is automatically reduced to save energy. If it is not enabled, please start by F2, enter BIOS found in Performance, set Speedstep Enable to Enabled. (Old BIOS is the Alt + P to the sixth page, modify the intel speedstep)

    (3) Use the standby, sleep and other functions properly. When you don’t use the computer for a long time, allowing the is in the notebook standby or hibernation, which can save electricity and extend the life of notebook computers. (Tips: Make sure video card drivers are installed successfully, the power management options can be set.)

    We will experience a period of time not to use laptops,should the battery be fully charged or need to be saved up?

    Optical long-term preservation will put batteries lose their activity, leading to the control circuit protection self-locking and can no longer use, the full power will bring long-term preservation security risks, the best preservation methods is to use 40% of the electricity and then stored in the cool and dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, it is best to take the battery out every month which can guarantee the good state of preservation battery and avoid the loss of damage to the battery power completely.

    How to View Dell battery? (In D610 Battery Case)

    Remove the battery, press the battery symbol, you can see the situation of five battery status lights. Two consecutive bright is representing 40% of capacity. Representative of the whole light power is sufficient, if the 135 light, then  the battery is damaged.
    Second, how to extend laptop battery working time as much as possible ?

    Here is a simple laptop battery capacity recovery method: unplug the laptop’s AC power plug.That is to say use the battery to give the power supply to the laptop , so when the system prompt “power shortage” warning, remove the battery from the notebook computer,  use a multimeter to identify the positive and negative poles of the notebook battery(usually there are multiple lead battery port), use a small light bulb or electric wire to discharge the battery until the battery runs out, then back into the notebook computer battery charge. Take this cycle for a few times, you can restore some capacity of the laptop battery.
           
    If you are a super DIYer, is still not satisfactied after using the above methods,you can also carefully open the laptop battery, skip the circuit board inside the battery to discharge the battery, it is better, but it requires you know some basic knowledge of electronics .

    But note that the completely abandoned batteries ,the capacity can not be restored, everything you do will be futile. However, there is still a way to save, that is, ask the masters to replace the battery cells, but the same model or core values are hard to be replaced .

    Fourth, when the notebook is restarted, in C: Windows prompt, enter the CD, press the [ENTER] key, go to C:.
    Fifth, enter battlfm, press the [ENTER] key, run the laptop battery calibration procedure, this time the computer is self-charging, do not care about laptop battery indicator will flash or beep.
    1, first appears five instractions in English, and then jump out of line prompt: “Insert the external power”, then plug in an external power supply;
    2, the screen says “charging, please wait for the next piece of information”;
    3, until the batteries are charged automatically to remind you when saturated will remove the external power supply, power supply will remove the self-discharge after the computer itself;
    4, the screen prompts the “discharge” until the machine shuts down the natural power down the way, do not power off by itself;
    5, to be automatically shut off laptop, connect your own external power supply, wait until the power indicator light flashes it means that no saturation has been charged, bringing the battery to complete the calibration process.
    OK! Your power display is back to normal.
