The next is to give laptop battery block “disembowelling her”, and its shell, but using ultrasonic technology to weld together. At this time may be preceded by a careful look to see if the battery laptop battery block on which the cracks, what is the direction of these gaps, consider what should gaps prized open with a blade and the screwdriver. If it does not work, then, you can also power down the cell blocks of four weeks to iron casing hot to open. This step is especially important, if done well, done carefully, then to the battery block the appearance of little impact, doing well, and that the battery block will see significant recovery after the “scars” in.
To open the battery casing blocks later, we can see the internal structure of notebook computer batteries had. At this time, we can look at a single digital multimeter measured the battery voltage to low voltage battery removed, the appropriate use our mail order batteries replaced. Here we must remind some single-cell aging after their performance for the voltage drop is not, for such a cell we can use digital multimeter to 10A current file, the red pen then the table cell “+” pole, the black table briefly touch pen look at the battery “-” pole (1 second or so), take a look at the display multimeter values, instantaneous short-circuit current in general will reach more than 5A, if the deviation from this value is too large, less than 1A, then this section of the battery has failed, it have to replace! After such examination the future, if there is no one can use, then it must be replaced dell Latitude D410 battery,dell Latitude D420 battery.
Removed the old batteries in a time when 10 million should be careful not to put the laptop battery protection circuit broke, and its lithium battery, but “protection of God”, when the battery is fully charged when the charger will automatically turn off power when in use , when the voltage is below the protection value will automatically stop when the power supply, or they will come to naught.
Replaced with the new batteries to go before we make a single cell combined into needs specifications. An analogy, I use Fujitsu’s little red book, compact, lightweight, is used to playing to type, on the Internet just fine, and the notebook computer battery is a rectangular 7.2V 2400MAH, and with 3.6V 1.35AH shown in Figure 4 The single-cell lithium batteries, they have to use four such batteries, two and two put together (that is, the battery positive to the positive and negative electric soldering iron welded to the cathode, alas, if you are not even what is in parallel What is the series can not understand all the words would advise you to do hands-on), composed of two 3.6V 2700MAH battery packs, and then these two 3.6V 2700MAH battery packs together in series to form battery packs 7.2V 2700MAH (larger capacity than the original, using longer!), and fixed with adhesive tape is good, this time it can follow the first wife of your laptop battery wiring methods, the new batteries of the battery pack is soldered to the anode protection circuit board to . Different brands and models of laptop battery voltage, capacity may be different, but the space inside the battery box will be not the same, which is carrying out “for the core” operation before it requires us to take fully into account in order to do so with confidence.
Then there is the fixed battery, and the prepared hot melt adhesive stick, with hot air gun-opening (if there is no electric hot air gun soldering iron effects are good), the drop in place a few drops, you can wait until after the solidification of the the shell of the original laptop cover, and this relatively simple, first in the case of some strong glue on the painted (AB glue, etc.), then the other half shell Zhanshang Qu, and so after a period of solidification can be tested.
Here are just knee surgery want to activate a second-hand laptop battery deal is fully charged and discharged, so that the maximum capacity of lithium batteries to resume. Approach is, in the boot of the state to close all power management, turning the notebook slowly discharge until they are completely without electricity, and then fully charged (slightly over charge for a while), can be repeated two to three times normal use.
Is believed that after such a big “for core” After surgery, your beloved laptop turn to the surging power of the listen whenever and wherever you call dell Latitude D505 battery,dell Latitude D510 battery,dell Latitude D520 battery.
