The number of ordinary lithium battery charge and discharge is only about 400 to 600

Battery calibration is an effective way to deal with aging batteries, in general, each brand will have a dedicated laptop battery calibration software. For example, IBM's ThinkPad series have a dedicated discharge software is recommended for all users to use IBM notebook. But the process need to be repeated three times to get the best results. Download the software and the implementation of discharge, the system will be prompted to create installation disks. Use the installation disk boot PCDOS, unplug the AC power supply prompted the discharge control software will automatically discharge. When all the notebook will automatically shut down after, and then we can connect the AC power source for charging, time control in 9 to 12 hours, repeatedly 2 ~ 3 times.

Laptop battery for activation, we find the right key to discharge the software. Unfortunately, if your laptop is not specialized discharge software, it can be shut down in the BIOS and Windows power management features, then do not run any programs in case the battery runs out, then recharge in the boot state to about 80% was repeated several times such as after manual "full of deep dark place." In fact, this approach aims to enable the continuous low current discharge batteries, which discharge state in our daily use is unlikely to be achieved, the effect of discharge and those dedicated basically the same software.
  Do not use under normal circumstances the battery, the battery life also with the more, the shorter life expectancy and a range of worse! !
I do not think the Internet on Shendu practice charge and discharge of any good, or occasionally to do some good, if a long time to do will certainly damage the battery, think about who put forward this proposal, of course, increase the battery business, his goods Activity loss can be sold, there is no memory effect lithium battery, it does not matter the depth of the charge and discharge, up to you what the problem is fixed, and there is a common use of the battery time is short, this can put the battery into the freezing cold, like waterproofing measures, and 3 days of the appearance on the line, the second is not into the electric charge, but the normal voltage measured with a multimeter, the general issue of the protection circuit, generally only replaced.
From the notebook was born that day, the Toshiba pa3534u-1bas battery has been accompanied by their side, no laptop batteries, can be said that can not be called the laptop "mobile computer", it is impossible for today's mobile business in the era of mainstream. With the notebook performance and technology continues to improve and improve the performance of laptop battery is also increasing, from the past nickel chromium batteries, nickel metal hydride batteries now used in lithium batteries have been likely to spread even after the fuel cell, small Some people concerned about this and closely related to what laptop - notebook battery, then let me go with you to understand about laptop batteries.   
General we have three kinds of batteries used, 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Nickel cadmium NI-CD, Ni-MH NI-MH, lithium LI, in recent years, In the notebook field has also been a fuel cell, its only by-product water and heat, no noise, the basic pollution-free, efficient power system than the normal high of more, to 43 ~ 58%, if the reaction heat is also use, the efficiency can be up to 80%! Is a clean environmentally friendly power. Because of its technology is not perfect, there are still many problems to be solved, now it cost, size, weight, fuel, convenience of access can not be and were extremely traditional lithium and lithium polymer competition.
       Nickel-cadmium battery NI-CD, since it was too early, so have many shortcomings of headache, such as: bulky, heavy weight, small capacity, short life, there is memory effect, etc. (nothing), is no longer used. Now mainly NI-MH battery Ni-MH and LI lithium two. Ni-MH battery which is also active in the battery industry, time, compared to other batteries, nickel metal hydride batteries to a number of more environmentally friendly, it is also by far the most environmentally friendly battery, while the lithium Well, is small, light weight, large capacity, low memory effect, charging time and short, well received by users like, but you will often see the back of the battery and dispose of lithium batteries handling instructions? Because the lithium batteries to discard will cause environmental pollution.
       Now, some people may have misunderstandings on the lithium batteries, lithium batteries do not remember that, in fact, lithium is not no memory, but memory is relatively small it looks not very clear. But also sub-lithium and lithium ion battery 2. Lithium long time ago there, and it is not safe when used often in charge when burning, burst, and this may be because the lithium element too active reason. Then there is the improved lithium-ion batteries, lithium inhibited by adding the element of active ingredients, so that lithium truly achieve a safe, efficient, convenient, and also followed the old lithium eliminated. As to how to distinguish them from the battery of the label can identify lithium as LI, lithium-ion battery LI-ION. Lithium and NiMH rechargeable batteries Another difference is that the number of charge cycles for the lithium generally only 400-600 times, specially modified products, but 800 times, usually with 2 years on the legs, which is why the general notebook battery manufacturers to take only 1 year for repair reasons. In contrast to the lithium battery, nickel-metal hydride rechargeable battery would much more, usually 700 or more, good quality battery can charge and discharge 1200, Ni-MH battery life than lithium batteries often had.
The following conditions need to activate the battery handling:
1. Just opened a new battery.
2. For a long time do not use the battery, the battery from the computer store the state office, is re-opening of this battery.
3. A long time do not use the battery from the notebook or laptop stand out of storage (more than two or three months), now re-enable this battery.

Activate the battery processing method:
      Activate the battery of chemical substances, to maximize the battery performance, need to repeat the charge and discharge the battery (fully charged and then fully discharge) three times. The so-called fully charge and discharge means: the normal boot order of 3% battery power to the battery (preferably a run out, can be divided into several times to power, but not interval too long), and then must immediately shut down the battery charge 12 hours.
      Here stressed the need to charge the battery immediately, because even if do not use the battery will self-discharge to 3% when the battery power consumption at this time if the battery charge time, battery self-discharge phenomenon can easily cause over-discharge The damage to the battery, over discharge lithium batteries is a major taboo.
      Activation of the battery charging processing, office machine must be turned off. If the time machine office waiting, hang and so state, when the charge to 3 to 4 hours of green power status light is no longer beating, the machine will automatically stop charging the battery, so can not be fully charged battery. When the discharge to 3% of the electricity, the machine will automatically enter sleep mode immediately, and you should restart the machine, the machine starts the process off the bottom left of the screen click the button, so the machine off.
      If the above operations have a good grasp of every detail, and the quality of your battery no problem, you can activate the battery well of chemical substances, to maximize battery performance, basically the normal battery after each use can charge to 100%.

Attention in use:
Battery is a "consumable", the cheap toshiba satellite pro a120 battery consumption depends on when you use the battery, do as the correctness of mode of operation, the operating frequency, the working environment temperature, storage time (for unused batteries) and other factors .

1. The number of battery charge and discharge directly to the battery life, the number of ordinary lithium battery charge and discharge is only about 400 to 600, 800, but also improved the product several times, once for each charge the battery on the end to the use of a step forward. (85% less power when on battery to charge, will be recorded and to increase the number of times a single charge.)
