The battery is the same charge of electricity

The battery is the same charge of electricity
, we must discharge. In addition to the normal discharge in use outside, why do we still run out of Panasonic Camcorder battery discharge it? Please come listen to me 11. When our camera due to run out of battery needed to charge the battery when we note that these exhausted batteries inside the other electrical appliances can continue to use? Furthermore, for each cell in the same one used in the electrical length of time varying? This indicates a problem, that is, the capacity of these Camcorder Battery is inconsistent. Why is there such situation? The reason is: We use electrical appliances, most are two or more battery cells made to link the battery packs, according to Ohm's law we can see that throughout the series circuit current is equal, as each cell's internal resistance can not be fully consistent with (even at the same time, the same production line out of batteries), then the voltage drop at both ends of each section and consumption of Sony NP-QM90 battery power, will not completely the same. This has resulted in the battery in the same imbalance in the relationship between the circuit, eventually leading to one or several batteries a long time in the "enough to eat, put could not finish," the state, until it is damaged. The reason why we post on the battery discharge, while abhorrent to eliminate the memory effect, on the other, so that each section of the panasonic CGA-DU21 battery as much as possible to achieve balance, together with full, finished with the release, synchronous work. Then how can we discharge it? Please keep in mind this truth: "discharge, we must separate each section of the battery discharge"! Otherwise, counter-productive, not as good as letting go. Discharge resistor or small bulbs can be purely resistive components such as discharge resistance controlled at 1.5 to 4 ohms, large discharge slow, too small to heat the panasonic VW-VBD210 battery. In practice, it is recommended to use three 3.8V parallel beads of the flashlight electrical discharge, resistance of 1.7 ohms at this time, discharge current of 700mA, less than 10 minutes, light bulbs went out on the discharge is completed, it is intuitive. You can also use the method of discharge resistors + bulb, Shi measuring about resistance, controlled at between 1.5 to 4 ohms on it. We can be converted to produce low-quality panasonic PV-BP17 battery charger discharger we want, is to buy an inferior charger (about 5 million), to better selection of housing, and this favorable for modification, and then remove the internal battery charger all electronic components, retain only the circuit board and battery clip, and then welded at both ends of each battery clip with our bulb or resistor, etc. In this way, we put appliances on the DIY better.
