Battery Is The Same Electric Charge, We Must Discharge.

battery charging:

Slightly different and Ni-Cr battery, nickel cadmium batteries is constant pulsating direct current to charge, and Ni-MH battery using a small ripple, the more smooth the DC charging. In urgent cases, two chargers can interoperable. Charge for the charge current should be master, how to estimate the appropriate charge current then? It depends on the battery's capacity to decide. In general, the civil standard 16 hours of battery charging, the charge current is: the battery capacity / 10, in units of mA. There are fast charge, fast charge current standard of 2.5 to 5 times, there is no uniform Laptop Battery

standard. We use the charger should try to use the standard charger, the charger's charging current to determine what? When we buy a charger, a multimeter to find a JS or own multimeter, plug the charger power supply, multimeter income into the DC current 500mA stall, red table document access battery charger chip, black table document connected with negative film, which , we can approximate by the multimeter readings to determine the charger's charging current, because the battery's internal resistance is small, so the multimeter readings close to the actual charge current. We can also use a number of automatic charger, the benefits of such a charger is a charger automatically stops, do not people worry about. In addition, we should try to avoid using fast charging, fast charging, the battery's internal chemical reaction is very severe, high temperature, which will accelerate the aging of the battery and shorten battery life. However, rapid charger when going out or emergency, but very useful oh.

6, the battery discharge:

People had enough exercise, and consumption. Battery is the same electric charge, we must discharge. In addition to the normal discharge in use outside, why do we have to discharge the battery run out of it? Please come listen to me 11. When our camera because the battery needed to charge the battery runs out, we noticed that these exhausted batteries inside the other electrical appliances can continue to use? And every cell in the same electrical length of time used different? This illustrates the problem that the capacity of these batteries is inconsistent. Why does this happen? The reason is: we use the electrical appliances, most are two or more batteries battery battery pack made of thread, according to Ohm's law, series circuit current is equal everywhere, as each cell's internal resistance can not be completely consistent (even at the same time, the same production line produced by the battery), then both ends of each cell's voltage drop and power IBM Laptop Battery

This causes the battery in the same circuit imbalance to the final result of which one or several batteries a long time, "enough to eat, put could not finish," the state, until its damage. The reason we were late on the battery discharge, while abhorrent to eliminate memory effect, on the other hand is to make each cell to balance as much as possible, with the full, complete with the release, synchronization. How then do we discharge it? Remember this truth: "discharge, be sure to separate each section of the battery discharge!" Otherwise, just the opposite, not as tightly. Discharge resistor or light bulb can be purely resistive element such as to discharge, resistance controlled at 1.5 to 4 ohms, too slow discharge, the battery is too small fever. Practice, the proposed use of three parallel 3.8V flashlight electrical discharge beads, then 1.7 ohm resistor, the discharge current 700mA, less than 10 minutes, light bulbs went out on the discharge end, it is intuitive. You can also use the method of discharge resistors + bulb, survey 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 a poor quality charger (about 5 dollars), to better selection of housing, which on conversion benefit, and then remove all the electronic components within the charger, retain only circuit boards and battery clip, and then welded at both ends of each battery clip on our light bulb or resistor, etc., so we put on the DIY Electrical better COMPAQ Laptop Battery

7, battery maintenance:

In the process of using the battery, follow the "full full release" principle, do not eat too much, or too tired. Be careful not to short-circuit the battery, this is very dangerous. Do not tear up the battery plastic skin, as it is easy to cause a short circuit, is equally dangerous. Do not disassemble the battery or the battery in fire. Long time do not use the battery should be full of storage, re-opening of the first discharge, then charge to use. Try to match the use. If you can do the above, we will always keep the battery in good condition, the better their services for the majority of DX. If you are a people meter, do not care, then I can do nothing, it would make me a pauper? Haha ...
