Have to talk about the laptop battery tips

1. what kind of laptop battery capacity?

Now look back to this test question, 7.4V5600mAh battery power capacity of 41.44Wh, and 14.8V4800mAh battery power capacity of 71.04Wh, it is clear that 14.8V4800mAh battery capacity is much larger. Speaking of this, some readers want to protest, because some use the netbook of 7.4V5600mAh battery life longer than 14.8V4800mAh large-size notebooks. The reason for this is that most of the low-voltage batteries are used in low-power netbooks or thin and light, and high-voltage batteries are used in large-screen, strong performance of the books. As a result, the notebook's power consumption several times worse, high-capacity battery life is also short is not surprising.

2. laptop battery experience

In use, we should be careful, do not place the notebook next to the fire or high temperature equipment, do not re-stress the battery. The most important thing is, once the deformation of the batteries, bulging, or even brace the shell, indicating that the batteries have emerged inside the pressure is too large, resulting in expansion phenomenon, the probability of becoming a bomb high, this battery is not used as well. If you find the laptop battery fever, or even already started smoking, this time, sprinkle feet run it, the battery is precious, books price is high, if it is for safety reasons, both can throw.

3. the most controversial thing: do not take the battery when using AC

The battery needs to be removed from the notebook when using AC adapter for adapter? Support removed users have two major grounds: First of all, the battery has been charged to increase the heat, but also greatly reduce the battery capacity due to memory effect; Second, the existing lithium battery charge cycle life is usually only 500 to 600 times, The battery on the books, will increase the number of charging and affect life expectancy.

In fact, read the reader of this article can be found, as mentioned earlier, the control circuit inside the battery has the function of cutting off the charge after the battery is full, so naturally there will be no battery always charging phenomenon, it will not Increase heat and shorten life expectancy. As for the memory effect, it is plagued by the problems of the nickel-cadmium and nickel-metal hydride batteries. However, since the lithium batteries have almost no memory effect after entering the lithium battery era, the memory effect can be neglected.

4.the hottest thing: the birth of lithium polymer battery

Familiar with laptop friends will find that in recent times, lithium-polymer batteries, a lot of laptops, especially thin and light notebooks, such as the Lenovo U350, MSI X340 and so on, have abandoned the traditional liquid lithium-ion battery go defeat to lithium polymer battery camp. In fact, in principle, the lithium polymer battery is nothing more than a polymer to replace the liquid electrolyte in the liquid lithium battery only, this seemingly humble change, will it affect?

Of course, first of all, the traditional liquid lithium-ion batteries have some pressure inside the work, so to be made cylindrical to enhance the pressure, but the problem comes, the battery can not be made thin, which increases the thickness of the notebook, In addition, each cell had to leave a gap, a waste of space. The polymer battery without electrolyte, which not only makes the battery thin, increase space utilization, because there is no electrolyte, there will be no boiling due to electrolyte explosion. Not to mention the lithium polymer battery capacity than the same volume of liquid lithium-ion battery about 50%. Really save space, improve battery life of the weapon. It is no wonder that it can quickly spread. To say that the issue of lithium-polymer battery, it is at this stage the price is still slightly higher, so it is more used in demanding compact, but when the price falls, the lithium polymer battery swept The potential of rivers and lakes.

5.the most tangled thing: silly battery capacity indistinguishable

Fifth, the most tangled thing: silly battery capacity indistinguishable

Many consumers regard the mAh, which represents the current capacity, as the battery capacity standard. In fact, the impact on battery capacity, in addition to the current capacity, there are voltage. For example, the battery is like a water-filled cup, the current capacity is like the caliber of the cup, and the voltage is the height of the cup. Must take into account the height and caliber cup to determine the overall capacity. Battery capacity is the same, the size of the real capacity is the power capacity, Wh, which is the current capacity of the battery nominal voltage obtained.

        For notebooks, the battery is like a behind-the-scenes hero, diligent, hard working for the normal work of the notebook. Most of the time, users basically do not feel it's there. However, the tiger is not upset, do not think it is a sick cat, aware of the existence of the battery is a good thing, but when it suddenly found its existence, it is often trouble, ranging from shortening the notebook life, but for it Of the rebirth spent a fee, and then crazy up, but also may carry terror charges, the battery explosion is very lethal. Battery those things, really not a small thing.
