Sony vgp-bps2c laptop batteries
From the chemical dissolution - deposition of the theory is concerned, due to charging, the positive and negative plates are usually not 100% converted into active material, the use of maintenance in normal conditions, will also appear vulcanization. Softening, there are different theories to explain, but microscope images, it can be observed during use, the battery's positive plate active material structure was changing. Less and less porous, and more, eventually to form coral-like structure. This process is bound to happen. Only with the cyclic process and the depth of discharge.Sulfide, water loss, softening of mutual influence.

We say: one using 36V10AH electric car, when it was new can run 35 kilometers. In the process of using the battery, the water loss may be the first to happen. Then, the water loss leading to electrolyte density, curing speed. The acceleration of curing when the increased water loss in the charge. These two factors will lead to a decline in capacity, while the positive plate is changing the situation worse: Negative of the curing process, will lead to charge the battery poles are present in the crystal (which is not to say took place sulfide cathode, which is due to charge voltage certain circumstances, the anode overpotential on the cathode caused by too much less than the potential, so that part can not be oxidized).

The above factors make the actual capacity of cathode were also down. When the positive and negative volume has fallen, the new battery 60% depth of discharge, for in terms of the old battery becomes different. Such as user per day riding 20KM, in the capacity dropped to only run 20 km when the battery every day to 100% discharge, depth of discharge bigger, soften the speed will increase. Sulfide, water loss, softening will also certainly exist. In the battery life-stage, we say that a piece of the battery is curing, it is that it was mainly due to the decline in capacity caused by sulfide. Rather than just curing it. Interestingly, the battery capacity, three main factors are the positive plate capacity, negative plate capacity, electrolyte volume and density. The softening, curing, dehydration is precisely the main changes in these three areas. arging, the voltage is normal, but placed on a period of time , the voltage will gradually move closer to 11V.
Within the power supply is greater than 9V with the R × 1K multimeter to find a table T by a fixed electrode, and the other table pen to touch the other two pins were able to turn the state, if the red table pen electrode was fixed access that PNP-type transistor, That electrode b and the pole, if the pen for the black table fixed access, compared with that NPN-type electrode and the electrode that for b pole; then use the red, black table pen then the remaining two electrodes, respectively, if the pointer has a larger swing clear instructions, PNP-type red pen next table for c very, NPN type is e very; black table pen then the PNP type is e very, NPN type is c pole. The above test, to rule out the human impact of resistance on the ohms file, b great to be left vacant and the remaining non-contact electrodes. Finger contacts can also be used b-polarity, the ability to enlarge the size of DC-estimation method to determine e, c pole.86, what is IC? What is short?The diode, triode part of the resistance-capacitance components and circuits to connect all the concentration of production in a semiconductor substrate to form cell circuits, known as integrated circuits referred to as IC IC PI5V330S.
