Were fed to exercise, to burn. Battery is the same, the electric charge, we must discharge. In addition to the normal discharge in use, we run out of batteries but also why the discharge of it? Please listen to me one by one coming. When our camera from the battery need to charge the battery runs out, we noticed that the battery runs out there in other appliances can continue to use? And each cell in the same appliance used in varying lengths of time? This indicates a problem, that is, the capacity of these batteries is inconsistent. Why does this happen? The reason is: we use electrical appliances, most of two or more batteries from the battery pack battery thread, according to Ohm's law we know that throughout the current series circuit is equal, because the internal resistance of each battery can not be completely consistent (even at the same time, the same production line out of the battery), then both ends of each battery voltage drop and power consumption will not be completely the same. This caused the battery in the same imbalance between the circuit, resulting in one or several batteries a long period of "food, put could not finish," the state, until its damage. The reason we were late on the battery discharge, while abhorrent to eliminate the memory effect, on the other hand is to make each cell to balance as much as possible, with the full, complete with the release, the synchronization work. Then how can we discharge it? Remember this truth: "discharge, be sure to separate each battery discharge!" Or just the opposite, not as tightly. Discharge resistor or light bulb can be used purely resistive components such as discharge resistance of 1.5 to 4 ohms, too slow discharge, small battery heat. Actual fact, it is recommended to use three 3.8V flashlight bulb parallel discharge resistance of 1.7 ohms at this time, discharge current 700mA, less than 10 minutes, the bulb went out to discharged, it is intuitive. You can also use the method of resistance + discharge lamp, sampling about resistance, controlled at 1.5 to 4 ohms on it. We can be modified to produce low-quality battery charger discharger we want, is to buy an inferior charger (about 5 million), better to pick the shell, which is a favorable modification, and removal of all electronic components within the charger, retain only the circuit board and battery clip, and then the battery clip in each of our bulbs on both ends of welding or resistance and so on, so we put on the DIY electrical good.
