DELL apart after the first look at the battery, which circuit is very complicated, I use the battery Laptop Battery protection circuit only to two points: first, exactly four cells in series circuit, but also two and four strings, so if it is the maximum capacity of the 2600mah batteries, can reach 5200mah, at least 80WH of electricity, second, there is an external power button on the instructions, you can keep abreast of the remaining power status, can do both discharge instructions, they can do charging instructions, double benefit.
Battery series
First connect the battery because it is replaced in my original N410C, and therefore contain welding of nickel films, This is one save trouble, and in accordance with the order of the battery, wire the battery into the box, the initial look at all of the company Apple M8244 Battery line, a total of 5, the length is enough, then directly welded.
Should first four cells in series together.
My welding sequence in accordance with the order from the cathode to the anode welding.
This is after all the welding appearance, though ugly, but this is only a test product, now just want to verify my thoughts.
Power output
For convenience, I directly choose the output circuit board of the positive and negative points, rather than copper to the card that the battery Apple A1079 Battery power output of the original.
Output of copper has seven, according to my experience, usually the outermost two copper is positive negative, you can use multimeter to know what the amount.
I was directly soldered circuit board, and to ensure that solid.
Look at, and above that two copper output is now negative, the above is negative, the following is positive, note that the positive and the positive batteries are not connected, otherwise the protection circuit will not work.
Look at how much the amount of voltage. . . .
How the output voltage is zero?
And then look at the amount of batteries Apple A1078 Battery voltage, a single voltage is 4.08V, then the combined output should be 16V or more ah.
In fact, forget a crucial step, and this is my be a private Cheats oh: D: D
This step is very critical, otherwise the battery voltage output is certainly 0
With a wire, the negative terminal of the batteries is phenergan black lines above the Okanagan and battery copper cathode output short-circuit what.
That is, the batteries positive Flanagan red line, and the output positive (that copper below) short-circuit can be about 1-2 seconds.
In fact, there is generally a positive or negative pole and is directly connected, typically batteries and battery negative anode output is directly Apple A1148 Battery connected.
I do not know what the reasons for doing so, but I think since the welding is a one up one by one solder joint, the protection circuit voltage of each chip to be different, a different order, so that through all the chips can be temporarily short-circuit power, and then moment and then release a short line of one-time connected to protection circuit to work.
Of course, this step can not do it, but to the battery into the notebook, then connect the power, when you win then the power comes, you will find that the battery has a voltage output.
The successful completion of
If, after these operations do not have voltage output, then it is unfortunate to tell you that your battery Apple M6091 Battery is a cylinder, that is, the battery is locked, and the output voltage can no longer use, except to unlock, with regard to unlock I do not said.
The effect. . . . . . A voltage of the bar, click the power button on the instructions. . . . Oh, also bright
Voltage With Oh, press the power button to power. . . . Light is also bright. . . .
I welded on the output interface, to ensure that positive and negative accuracy, close your eyes, direct plug to the laptop power supply interface to go.
Press the power Acer BTP-43D1 Battery button, boot, and a one-time success, a look into the system:
There are 56% electricity, this should be my built-in battery power is left, but the lower right corner of the icon display is an AC plug, that is not to my battery, think also, voltages are similar, how can you charge it .
Notebook is now the state is the default for the power adapter. But now is not yet known when the battery power is exhausted, it can automatically switch to internal battery-powered notebook, if so, then I basically reached the objective, the next is to the battery after a series-parallel to increase capacity.
(Full text conversion and initial testing process finished, over a period of time on my real high-capacity battery pack, as well as some charge, please look)
Show what I have prepared batteries: Canada's MOLI batteries, new, 3 and 4, a total of 12 strings, a single volume estimated at 2400mah or so, I do not know Acer TravelMate 220 Battery the specific
