Network several times in the back flush cycle every place is full of electricity and ended after the battery power to open, measuring the voltage of each battery pack to find a group of "different" on the charge when voltage to reach 4.2V or even more than the first, leading to the cessation of all battery yf976, and unloading when was the first to reach 3.6 or even less, is a typical decrease capacity. And the biggest of which still can be a battery problem. This group of cells separated from the voltage, respectively, found that a battery voltage is low, only about 3.2 V, a separate charge of their tension quickly reach 4. 2V, less than a minute of time, the Dell Inspiron 6000 battery basically has no ability to speak with a light bulb when he met the discharge, is the fundamental output current can not provide even less 1 mA, measuring its resistance, has reached more than 2K seems to have been discarded.
As a result of "shock therapy" after the restoration of normal cells, but not reached 4 charging voltage. 0V, it seems that it is "the dumplings pot - draw no power" to weld again a battery discharge followed by the use of time of 90 minutes, has been near normal level the battery.
However, when the load is quickly filled, and disturbed mind soon. It was a shock, is less than half an hour, open a test, just fix the bad and the battery.
Not always have to use a "heart to recover," ah, so the value of the lost.
This section of the final decision to perform an operation of the battery, and then they can not, then replace the batteries. Scaling of the batteries, remove the insulation near the top of the cathode and found a slight corrosion on everything, but I do not like leaks and trails, and save. Halogen lamp battery positive and negative, there is no response Given the previous "Anatomy" the same symptoms when the batteries are inside the battery with the cathode of the battery between cathode cap (pressure, not soldiers) oxide occurred, resulting in increased resistance and battery at the end of his life, and the internal battery is still good. oxide layer in the case is not serious as long as the battery cover to strengthen contacts and internal battery that is in the battery does not leak if damaged can be restored. The easiest way is to increase the battery forceps are negative (an insulating film pad), while measuring the Dell Inspiron E1505 output voltage of the battery (or current), while vertical extrusion batteries once the output voltage of the battery increases, the current gain (the change is often the leap in nature, relatively large changes) to stop immediately, the HP Pavilion battery will be able to repair.
The upper edge of the lid of the cathode of the battery near the mouth ventilation valve cutting pliers, then immediately measured and the battery has been restored, increasing the output current immediately. To insurance, battery cover in the week between the edge of the chisel a bit more in order to increase the contact area to ensure that the use of effects.
