How to notebook computer battery charging?

There is also a need to have a good conductive nature, reduced battery internal inertia.
Although lithium-ion batteries are nickel-cadmium batteries little memory effect, the theory is the crystallization of memory effects in almost lithium batteries will not have such a response. However, lithium-ion rechargeable batteries in several capacity will decline after release, the reasons are complex and varied. Mainly negative electrode material itself is changing, from the molecular level, is the negative electrode of a lithium-ion accommodate structure will be gradually 18th hole, plug; From the perspective of the chemical is being cathode materials reactive passivation, a deputy response generated stable other compounds. Physics, material will gradually falling off as a positive situation, in short, can ultimately reduce battery provides free discharged in the course of the lithium-ion mobile number.
An overcharge and excessive discharge will be lithium-ion batteries are cathode caused permanent damage, from the molecular level, can intuitive understanding will lead to excessive discharge of carbon cathode excessive release lithium ion and make their films at the structural breakdown, excessive charging will be too much lithium ion hard into the structure where the carbon cathode, and lithium ion no longer makes some release. This is why normally equipped with lithium-ion battery provides discharge control circuit causes.
Unsuitable temperature will trigger internal lithium ion battery other chemical reactions generated We do not want to see the compounds, so in many lithium ion batteries are negative electrode temperature divide between a protective or electrolyte additives. In some cases the cells warming, composite membrane electrolyte membrane Kong closed or degenerative, batteries internal inertia increased until open circuit, the battery no longer warming, ensuring battery charging temperature normal.
And lithium-ion rechargeable battery or can upgrade the actual capacity? Experts clearly told me that this is meaningless. They even said that the so-called three-person before use on the "back" in their knowledge of the two Dr., also can not imagine what it necessary. But why many people leave after dark place in Battery Information marker capacity will change? Will be mentioned later.
IBM notebook computer with a lithium-ion battery charging control chips and management chips. These chips are a series of register management, a capacity, temperature, ID, the charging state, the number of discharge values. In the use of these values will gradually change. I personally think thatcom IBM notebook puters in use on the "whole person should use a month later on a" practice is the main role should be to amend the register of improper value, making battery charge control and the actual nominal battery capacity coincide.
Charging the battery charging control chip main control process. ThinkPad lithium-ion batteries charging process is divided into two stages, Hengliu provides fast stage (a yellow battery light) and Hengya current decline phase (a battery light green lights. Hengliu Express provides stage battery voltage batteries gradually rise to the standard voltage, and then in the control chips into Hengya stage, voltage not been made to ensure that no longer rise, with the current battery consumption to rise gradually weakened 0, and the final completion of charging.
Statistics chip sales through the records discharge curve (voltage, current and time) can be calculated sample cell capacity, and that is what we read in the Battery Information Lane Estate. Values. And lithium ion batteries used in numerous after discharge curve will be changed, if the chip had not had the opportunity to once again read out a complete discharge curve, the calculated amount is inaccurate. So we need to take a deep cover calibration cell chip.
Finally, I think the maintenance of the batteries :
1. Not deliberately guarantee every person to have the power to take End;
2. Time to do a deep-protection circuit provides controlled release of power to amend batteries statistics, but it will not enhance the actual capacity of your batteries.
3. Long-term idle batteries to be placed on the shady places to weaken its own internal passivation reaction speed.
4. Protection circuits are also unable to control cell self discharge, the batteries do not have long-term, should be made into a certain amount of storage in order to prevent the batteries from over-discharge led to the discharge of excessive damage.
In fact, not too many have to take into account the use of batteries attention, in other words taking into account also is not much use. How many times a cell can use, perhaps more differences from the manufacture of individual differences cell itself, rather than using methods. Choice of a good reputation in the notebook computer brands, the use of long-life batteries is the one of the guarantees.
