Most people use lithium batteries approach also stay in the use of nickel-metal hydride nickel-cadmium batteries errors in the old methods. This article details the thinkpad t40 battery is currently the most widely used lithium batteries the right way to use the number of errors on the use of statistical sampling carried out, focusing on cell phone lithium battery charge the correct way the first three.

Introduction

Lithium-ion batteries since its inception in 1990, because of its excellent performance has been rapid development and is widely used in the community. Lithium-ion battery to other batteries by the incomparable advantage of the rapid occupation of a number of areas, like the well-known mobile phones, notebook computers, small video cameras, etc., and the growing number of countries the batteries used in military purposes. Application shows that the lithium-ion thinkpad t40 battery is an ideal small-scale green power.

We often say that the advantages of lithium-ion batteries is targeted at the traditional nickel-cadmium batteries (Ni / Cd) and nickel-metal hydride batteries (Ni / MH) in terms of the. With a working voltage of high specific energy and long life cycle in the self-discharge rate is low no memory effect and so on.

Li-ion thinkpad t42 battery is currently recognized as the basic principle is the so-called “rocking chair theory.” Lithium battery charge and discharge is not achieved through traditional means of electronic transfer of a child through the layer of lithium-ion in the crystal Zhuang material discrepancies energy changes occur. Impulse discharge in normal circumstances, the lithium-ion entry and exit is generally caused by changes in layer spacing, while the crystal structure without causing damage, so from the red to reflect in terms of discharge, lithium-ion battery is an ideal reversible battery. In the red discharge lithium-ion battery positive and negative and from access to, as the same as in the rocking chair was rocking to and fro between the negative and therefore the image of someone known as the rocking chair lithium-ion battery cell.

Lithium batteries and nickel thinkpad t42 battery charge and discharge characteristics are very different, the access to all the serious official had technical information are stressed and over-discharge rechargeable lithium batteries will, in particular liquid lithium-ion battery causing great harm.

Lithium batteries(thinkpad t40 battery) for everyday use in the process of misunderstanding. For the lithium battery “activate” problem, many say is: recharge time must be more than 12 hours, repeated three times to do in order to activate the battery. This “The first three charging more than 12 hours to charge” was obviously from the nickel battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that a beginning of miscommunication. After sampling, we can see a considerable number of people confuse the two kinds of battery charging method.

Accordance with the standard charge and therefore the best time and the standard method of charging, in particular, not to carry out more than 12 hours of super-long charge.

Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.
In addition, lithium batteries cell phone or the charger will automatically stop after the thinkpad t60 battery is full charge, there is no electricity nickel charger for 10 hours of the so-called “trickle” charge. That , If your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change and the quality of safety.

So, your battery will be a long-term at the brink of danger. This is also another charge against the chief reason.
With regard to lithium-ion battery charge and discharge cycle test table, on the cycle life data is as follows:

DOD is the depth of discharge in which the English abbreviation. Can be seen from the table may be the depth of charge and discharge times, 10% DOD cycle life than when the 100% DOD for much longer.

If the actual charge equivalent to the relative total capacity: 10% * 1000 = 100,100% * 200 = 200, the latter a full charge and discharge, or better than some. But the life of lithium batteries are mainly embodied in charge and discharge cycles, this cycle is an absolute concept, the last use of 30% power, full power, the next time the use of 70% of electricity, but also full of electricity, this happens to be a charge cycle. Therefore, lithium batteries, or inventor to follow the slogan “that is used that is sufficient, that is, charge-use” approach to the use of lithium batteries.

Extraordinary time and fully recharge an empty battery will cause over-charging and over-discharge, lithium-ion batteries will be positive and negative result in permanent damage, from the molecular level, the excessive discharge of carbon anode will lead to excessive release of lithium-ion and makes it lamellae structural collapse, over-charging of the lithium-ion will too hard go into the negative carbon structure, causing some of the lithium-ion can no longer be released. This is why lithium-ion batteries are usually equipped with charge-discharge control circuit causes. Lithium-ion batteries(thinkpad t400 battery) are generally with the management of chip and charge control chips. Which management chip in a series of registers, there is capacity, temperature, ID, charge status, discharge frequency values.

These values are in use will gradually change. Use the “use of a month or so should put a full-charge” approach to a major role now is to fix these registers where the wrong values, making the battery charge control and the nominal capacity of the battery match the actual situation. Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample battery power, this is what we read in the Battery Information inside wh. Value. The lithium-ion batteries in repeated use, the discharge curve will change, if the chip has not been opportunity to once again read out a complete discharge curve, which is calculated out of electricity that is not accurate. So we need to deep charge-discharge to calibrate the thinkpad t40 battery chips.

The first three rechargeable lithium batteries the right way and everyday use considerations.

The first three charging when there is no need for an extraordinary time of recharge, such as 12 hours to activate the battery, charging circuit would have meant the protection and planting is also useless.

To place a long time unused, or that the charge that is frequently used for some time, the methodology is a complete charge and discharge, after which the battery charge on which you can use that only long-term use is only necessary for complete charge and discharge once again re- calibration.

If you want to place between a battery do not, the proposed charge to 40% further placed in order to protect the lenovo battery.

Finally, the lithium battery life is mainly reflected in the charge-discharge cycles, this cycle is an absolute concept, the last use of 30% power, full power, the next time the use of 70% of electricity, but also full of electricity, this happens to be a charge cycle.
