Point, the problem occurred: it is now (2 times faster than normal) are filling power, in the process of discharge is suddenly 70% of the time "battery, AC power Please insert" amount of warning that The show is now dead prompts 5%Beginning of a long time will lead to memory effect and I do not use the battery, we need to do some deep cycle However, after several full charge, after release, very little improvement is about 45% of the power in half the time is small, there is still a problem The largest section of the multiple problems Inspiron 1520 battery pack or "black sheep", may have removed it!

All locations are full of electricityAfter that open after battery power, the subsequent discharge cycle, the red a few times to measure the voltage of each battery pack, "different" to find a group: when one reaches the charge voltage 4.2 V or even first than the, lead to a suspension of the entire VGP - BPS2 battery charger at 3.6V is the typical decline to reach the first discharge capacity or less And its largest of the battery may have a problem Measurement of cell voltage, respectively, the battery voltage of about 3.4V, the voltage quickly separate fee, less than one minute of time this group was separated from 4.2V low until found, A1185 battery no more than that basically said 2k to discharge bulb was found that the capacity is reached, it is to measure the resistance, the basic output is also less than 1mA to provide not now seems to have been abolished
After restoration of normal cell "shock therapy" but as a result of the charging voltage of 4.0V not reached, it "is gyoza pot - it is after the electrical discharge of the battery backup" does not seem out of the soldering Maximum time is 90 minutes by the use of which is close to a normal level of the battery

However, the turbulent mind as soon as charges are quickly filled Discharge, it is less than half an hour to open a test right now to fix the faulty battery

Is always, "This is a Ah to recover the lost value on" uses the heart

The final decision, holding a battery-operated, you are in this section is not, then, and then replace battery Remove the cap and cathode stripping insulation around the batteries to avoid corrosion found a slight, I like the battery fluid and trace, not even save it as The halogen lamp from the battery positive and negative, when the output between the positive battery cell positive electrode cap (pressure, with no welding) account no response is received within the battery and the oxide occurs, "Anatomy science "is taken to increase the same symptoms as before, resistance and life, and the end of the battery, the result of the internal battery is still good In the case of the oxide layer, the internal battery contacts and to strengthen the results can not leak to restore damaged if the battery cap as long as the battery is not serious Inspiron E155 while the other measures the battery voltage, battery vertical extrusion, once the battery voltage, the simplest way is increasing the current increases, is to step up the battery clamp (1 insulation pads membrane), (or current) is negative (changes frequently in nature, a relatively large jump change) is now is to stop the battery can be repaired
Positive cap cells, the battery is disconnected and then immediately measure pliers, and found that it was restored to the output current increases, the top edge of the mouth next to the ventilation valve For the purpose of insurance is between the chisel edge of the area to increase contact details to ensure the battery cap of one week, you can use the effect

Re-wrap the battery, solder back, XPS M1210, the battery pack, charging and discharging Use the time to reach more than 90 minutes

Measured using the software and test again, 32.07Wh, a decrease of about 20 percent less capacity from the current source 38.88Wh, this is the actual discharge process, there was no decline in the jump The increased discharge capacity of the red after a few cycles Using the current two months has been made, everything will be fine
