To work longer books: How to make the notebook lithium batteries
Now more and more people use the notebook as one of the main components of the notebook lithium battery problems also will increase. So how good notebook lithium batteries with it? Grasp the main points:
1. An appropriate charge and discharge current.
2. Insufficient to minimize the discharge of charge or over discharge.

While the battery is a consumable, lithium-ion battery Toshiba pa3594u-1brs battery is no exception. But no one wants to use up the battery fine spirit of God, to age the look is finished and do not rattle, no one wants to start his own half dead battery does not pull a living, has been such a rub on the two or three years, people take experience about how the ribs going, do not you say?
Well, get down to business, following the battery began to speak. First, to explain that only lithium-ion batteries.
Appropriate charge and discharge current
General literature and the national standard on lithium-ion battery lithium-ion batteries on the said charge current should be between 0.2C to 1C. It is said that the charge current battery capacity, such as your battery is 4AH, then the 0.2C charge current is 0.2X4 = 0.8A, that is the charge current should be between 0.8 to 4A. In general, the charge current as small as possible within the permitted range, lithium-ion battery should be a constant current charging the start, Acer aspire one zg5 battery in my IBM R31, this current is 2.8A, equivalent to 0.7C, is charging its own circuit control, can not set their own. Although this charge does not exceed the standards for indicators, but it does relatively large, especially when the battery capacity decline for some time, the charge current may be more than 1C. Laptop charging time is now also become targets regardless of the user, the manufacturers have to charge current set so high.
So first step is to reduce the charge current. I have friends working in the laboratory, a variety of equipment readily available to test a bit in him. On the first string on the power output of a resistance to try, the result current is reduced, but became intermittent charge, this is not a good thing. Through trial and error, 4 Ohm is a more ideal value, this time around 0.8A charge current is very stable. This is only the current flowing through the machine power connector, the battery charge current is estimated to be larger, it should be slightly larger than 0.2C. Specific to a different machine, this value may be different. Also with the rise in battery voltage, charge current will be reduced, but decreased only slightly, less than 0.05A.
In this charged state, charging circuit seems to not work, the battery indicator does not light. Etc. After the battery Toshiba pa3465u-1brs battery voltage up to 12.6V, charging circuits came into play, the battery into the trickle charge state, this time does not matter whether the series resistor, the charging current is controlled by the charging circuit, the last full charge after the charging circuit automatically end. The charging time is about 5.5 hours, if not resistance, charging time is 3.5 hours.
