We buy a notebook, is the value of its mobility. Today's laptop computers, are all built of Health have a good, so we are all generally small size of the view that mobility is better. In fact, not necessarily to decide whether the notebook mobility of qualified, but also an important factor - Fujitsu FPCBP80. Why? We can imagine that if you buy a smaller size laptop, but battery life is not ideal, but not the kind of depressed mood to vent. Today, on Xiaobian to tell you is that, on the notebook's battery-related knowledge.
First of all, we have to find out the type of notebook batteries. At present, the use of the laptop batteries were divided into three types: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium batteries. They said that on the side: Ni-Cd NI-CD, Ni-MH NI-MH, Li-electric LI.
Nickel-cadmium (niege) Battery: It is the end of the 19th century by the Swedish inventor of such batteries have the so-called memory effect, what is the specific memory effect, we just give an example, you: When a battery is fully charged, It can be a continuous electrical discharge 60 minutes. Now we have to use this section of the batteries for electric discharge, discharge to 30 minutes to stop, and then this section for charging the Fujitsu FPCBP77, Fujitsu FPCBP68, good and sufficient power to continue to discharge after 30 minutes, each time for not fully discharged, after repeated operations N This section will have a battery memory effect, after the use of the process, when the battery discharge after 30 minutes, it is no longer the output current, that is to say, this section of the battery capacity has been cut in half. Ni-Cd memory effect is very serious.
Ni-MH battery: Ni-Cr early battery alternatives, greatly reduces the nickel-cadmium batteries in the existence of a "memory effect", which makes nickel-metal hydride Toshiba PA2487U , Toshiba PA3107U-1BRS , Toshiba PA3383U-1BRS can be more convenient to use. Nickel-metal hydride batteries and nickel-cadmium Fujitsu FPCBP63 , Fujitsu FPCBP95 are basically the same as the cathode, are for the positive electrode nickel hydroxide. The main difference is the nickel-cadmium batteries used in the cathode active material is cadmium, nickel metal hydride batteries and high-energy based hydrogen storage alloy for the negative electrode, the nickel-metal hydride batteries have more energy.
Nickel-metal hydride batteries are the main characteristics of 5:00:
1, the energy density than nickel-cadmium Toshiba PA3384U-1BRS twice as large.
2, round after round of 500 to complete the cycle of charge and discharge.
3, with the door side of the charger can be recharged in one hour fast charge.
4, self-discharge characteristics than the nickel-cadmium batteries, rechargeable can be retained for a longer time.
5, up to 3 times more efficient discharge in a row.
Lithium battery: lithium battery is from a class of lithium metal or lithium alloy anode materials for the use of non-aqueous electrolyte solution of the battery. 20 of these batteries is the actual success of the development of a new type of high-energy Toshiba PA3285U-1BRS , Toshiba PA3191U-1BRS , Toshiba PA3166U-1BRS, has a high-energy, high-voltage battery, operating temperature range, long storage life, and other advantages.
Lithium batteries have a home page features 7:00:
1, high-energy high-density. Lithium-ion batteries are the same weight capacity of Ni-Cd or Ni-MH battery half of the volume is 40-50% of the nickel-cadmium, nickel hydrogen 20-30%.
2, high-voltage, a single lithium battery's voltage to the work of 3.7V (average), the equivalent of three series of nickel-cadmium or nickel-metal hydride Toshiba PA3331U-1BRS , Toshiba PA3098U-1BRS , Toshiba PA3084U-1BRS .
3, pollution-free, lithium-ion Toshiba PA3399U-1BRS , Toshiba PA3395U-1BRS do not contain such as cadmium, lead, mercury and such harmful metals.
4, does not contain lithium and lithium-ion battery does not contain lithium, which is not on the Prohibition of the transport plane carrying aircraft in the lithium battery, and other provisions.
5, high cycle life, under normal conditions, lithium-ion Toshiba PA3250U-1BRS charge and discharge cycles can be more than 500 times.
6, no memory effect, the memory effect is the nickel-cadmium batteries in the charge-discharge cycle, reducing the capacity of the battery. Lithium-ion batteries that effect does not exist.
7, the use of rated voltage of 4.2V voltage constant current charger can make lithium-ion battery in 1-2 hours to be in full charge.
Well, to find out about the battery type and characteristics, we come to find out the battery power of the issue.
There are a lot of people buy a laptop when the battery is about to start, and configure their business only on a single reading of the battery capacity of xxxxmAh not write battery voltage, in fact, the true reprint battery energy is not the size of the unit mAh but Wh. Battery power is based on a formula: battery power (Wh) = battery voltage (V) x battery capacity (Ah). Please note that here is the battery capacity Ah, not mAh, 1Ah = 1000mAh. For example, touch the Toshiba PA3356U-1BRS ,Toshiba PA3291U-1BRS block is the nominal 10.8V/2200mAh, it is the power of 10.8Vx2200mAh/1000 = 23.76Wh. The battery voltage and capacity in general will be marked on the battery, their calculations on the know. Some manufacturers will not be marked on the battery specifications, so we can only use the software to be tested.
Battery power in this respect we need to note that the replacement of the battery problems. And the battery charger is inseparable, that is, we are talking about normal power supply. If you want to replace the battery, you may choose the same model to use the same power, we can be assured that the replacement of business when you have to be clear. At the same time, the Chargers also need the attention. All notebook models of voltage and current, and even interfaces are different, common to a variety of models with "compatible charger", more expensive than the original. Even the interface is like, different voltage and current notebook is not working. If the voltage lower than the current standard of value, then the laptop at full speed in the work will lead to shortage of power supply, so that the battery is a lot of harm. If the voltage higher than the current standard of value, notebook and even the roots will not be able to boot or not to start charging, the board may eventually lead to burning. So choose a good charger, the notebook's Toshiba PA3506U-1BRS , Toshiba PA3591U-1BRS , Toshiba Portege 4000 maintenance is very important.
There are many of my friends are concerned about this problem because there is no knowledge that it dares not reckless action. On the one hand, is a charger, if the batteries die, you can replace the batteries.
In fact, there is also a battery inside the batteries, long way from our usual battery used almost only to be larger. Many of the batteries are designed with a self-locking function, in other words, once the Toshiba Satellite A10 Series , Toshiba Satellite A100 out of control circuit, it will enter the self-locking state. Into the self-locking state battery, will not be able to work on the battery become obsolete, only certain way in order to unlock, which only professional engineers can. Therefore, we can only choose to replace the battery core. Battery replacement batteries can not be so arbitrary, and we hope to find more professional personnel to replace. If his replacement, an end-of-life battery is small, but that effort did not succeed in the fight against what is the most depressing.
Most people should be worried about is that the bombing of the notebook, in fact, we may very puzzled why the battery and then the explosion? The main reason is that manufacturers should be poor-quality work, resulting in the use of short-circuit in an explosion injuries. However, there are also a part of the reason is because the user caused by improper use. Many users may encounter such problems, only when the battery charge to 99% charge is less than 100%. In fact, this is only a problem if the charge to 99% can not continue to charge the battery, Toshiba Satellite A70 , Toshiba Satellite A75 that has been filled. If we or always sufficient, the last on the battery is likely to lead to an explosion.
On the notebook's battery maintenance, Xiao Bian here with you no more, I believe there are many on-line article on battery maintenance. With knowledge of the battery Xiaobian only know so much, we can provide help so much, and I hope you can help
