We all usually think that I use the laptop with AC Adapter or laptop battery? Can I prolong the laptop battery life if I do not use the laptop battery? How long is the span of my laptop battery? Has Li-ion laptop battery the memory effect? Lithium battery is memory effect is very small, almost zero. Can I use the AC Adapter directly? No, the reason is lithium battery inside ion if long time in a relatively quiescent state (the stationary relatie, namely the battery without electricity or a small quantity of electricity time. Long time how long? : six months or so), will completely lose store electrical energy function. If you do not want to use the laptop battery, you should charge 90% electricity of the laptop battery and pack it in cool place. In fact, a piece of eight core of lithium battery life (remember, is using life) are charging around 800-1200, if below this figure, the battery quality has a problem. How do we know we filled many times electricity? For example, the IBM ACCESS, IBM have inside a can view of the battery number, we can clearly know first charging time and battery health. Other laptop should also have such similar functions, you can look it yourself. If you are around ac adapter, you should connect the laptop with AC Adapter, ensure AC battery came on again after boot! Remember! Now, our batteries are slightly current charge, the mainboard power protection will not let machines have any questions! At this time the situation is not calculated rechargeable battery times! A year come down your battery only filling 50 times and 600 times which do you like better? Notebook computer batteries activation treatment and use if undeserved, can make your battery hurt, shorten the life of the battery. Activate cell chemicals to maximize the battery's performance, need to repeat charging and discharging (by battery is fully charged, and then to completely discharge) three times. So-called full charge is to point to: normal boot makes battery depletion to 3% battery power (preferably a drained, also can be divided into several times to power consumption, but unfavorable interval is too long time), then must be immediately to battery charging twelve when shutdown. Emphasis here must be immediately to the battery to charge the battery, because even if they do not use also can undertake ego discharge, when the battery depletion to 3% power, then if not timely for battery charging, self-discharge phenomenon is caused extremely easily battery of discharge and damage the battery. If the above operating every detail is held good, and your battery quality have no problem, can very well activation cell chemicals to maximize the battery's performance, basically battery later in normal use every time enough to 100%.

Generally speaking, most parts of negative composition inside laptop battery are determined by internal resistances and the difference to actual capacity. Of course, these two figures can be transmitted to different levels of performance when required situations are varied. Hence, this simple indicating device is absolutely necessary.



Composed by sensory unit and transformation components, the transducer can record the output voltage and current in all conditions while these figures cannot be figured out directly. So are conduction and domination. For this reason, the updated section has applied with electrical signal directly to complete indicating by measuring circuit which can check on real-time output power.



In addition, with the development of integrated circuit technique, the former output power energy from transformation components is still hard to indicate, record and deal with large amount of indexes so that circuits come to be chipset gradually. Subsidiary by external supply, complicated new types of components have come into being like bridge, modulation control, oscillate and high input impedance non-inverting circuit.



Therefore, laptop battery life can be calculated by set procedures instead of measured by pure specifications carefully. Still, some professionals in the industry don’t believe in such new devices but the classical universal electric meter as a substituent.



It is truth that maybe in terms of accuracy, these transducers are not perfect enough to pit against meters to some extent, but what about the process of calculation? After all, except for capacity and nominal value, there’re many other factors to influence on actual standby time of laptop batteries.



Anyway, the two simple ways are still regarded as the first-class ones in the market to learn about internal resistance and current capacity according to my own opinion. As for beginners, I recommend to use transducer which won’t cost you too much time in the course.
