It should be activated when you use the new battery, so-called activation is charge and discharge the battery completely. Many people say that activation need to conduct 3 to 5 times, in fact, according to many experiments prove that only 2 or 3 times is enough, because now a lot of the battery can reach 98.6% of rated capacity after the first fully charged, the second in general can reach the rated capacity. It was also stated that activation should charge to be sufficient 12-hour enough, in fact, it is still not correct, because when the control circuit considers that the battery is fully charged, the battery charging circuit was terminated, to continue on the battery connected to the power supply is also a milli-meaningless, but if you like 12 hours enough charge also decided by yourself. In addition, when your battery performance significant decline, you can fully charge and discharge several times, battery performance will be improved.

The correct full charge and discharge method is to first turn off the power-saving options in the Bios, and then in Windows “power scheme in the” all of the election of “never”, in the “Alarm” option to remove all the hooks, When the power consumption of about 5% left to restart the computer, in the self-test information screen push the keyboard Pause button to pause, and then close the screen so that the battery in the case of low current discharge until the shutdown automatically, one fully charged to complete.

To extend battery life, need to be aware of the daily use of energy-saving, and you can select the Bios in the Power Options “Maximum Battery Life”, also in the Bios you can close some commonly non-used equipment, like port, infrared, etc; in Windows the “Power Management” dialog box, select the appropriate power supply for your program; of course, you can use some CPU cooling software allows to cool CPU to achieve energy-saving purposes.

The most common situation is that the laptop is running at full speed when using battery, the current is too large to result in automatic protection. For example, to capture the contents of DVD discs from the drive into the mobile hard disk, both host and peripheral are consuming power, it is likely to make current beyond the battery standards of protection, in this case do not panic, as long as to disconnect peripherals to wait about 10 minutes and then reboot.

There is also a common situation that using laptop computer in a hot environment and high-load operation using the battery, so that the ambient temperature plus the heat generated by the battery self-discharge may exceed the battery protection circuitpreset temperature. Encountered such a situation should remove the battery and placed in a cooler place (remember not to put into the refrigerator for frozen!), After half an hour should be back to normal. The damage of high temperature is relatively large to the lithium battery, less than a last resort should be avoided to high-load use the laptop in high-temperature environment.

In order to maintain the BIOS state, a lot of notebook computers have the battery calibration option, simply speaking, this function will make the notebook battery full charged and complete discharge to no electricity, and then re-filled, this have a certain correction for the accumulated error caused by long time not completely discharge. However, please note the correction in the BIOS spent rather a long time, if you do this, preferably before going to sleep.

Many models also have Windows discharge functions. This can save time, emendation while working. Battery Calibration should not be too often, the frequently deep discharge can shorten the battery life, it is recommended two to three months to do it once.

To ensure the laptop battery can maintain a better working condition when in use, there are some considerations.

(1) New bought battery should fully charged at least once, then power exhausted, formally use only after the second charge. This can fully activate the chemical effects of lithium batteries.

(2) When the notebook computer using AC power, remove the battery out would be preferable to avoid them always in charge state. It’s best to shutdown the laptop when charging, make the battery fully charged. Also, do not unplug the power in the charge half-way, and use after charging finished at least 30 minutes.

(3) If using battery-boot after a few minutes, it is best not to take over the external power supply, but to let the battery charge after runs out.

(4) Sometimes connect to AC power the battery may not charge, it is because some vendors designed to prevent battery record over-charge cycles and deliberately, and only less than 95% when battery started charging. When charging, if the shows the battery is already full, do not cut off AC power, because the battery power at this time may be just about 80%, it is best to maintain an external power supply for about 30 minutes charge time-out in order to ensure a fully charged battery.

(5) The battery should be placed in shade in order to weaken its internal self-passivation reaction speed if you don’t use it for a long-term.

In fact, there is not much to take into account about the battery usage, the the difference number of times a cell can be used comes more from the battery itself and differences in the manufacturing process, choose the laptop has a good reputation is no doubt one of the guarantees for long-life battery in the future.

1 The more the battery charging, the faster the life expectancy decline?

Lithium battery life relate to the total battery charging power, unrelated to the number of charge. That is, the total charge of a laptop battery is constant when at the factory, and for the lithium battery life, the deep discharge and charge, shallow charge and discharge impact little.

2 The instructions of my laptop written the using time is 5 hours, why is the difference so large?

The battery using time on the instructions is an ideal test time in principle, based on uniform standards in IT industry testing methods obtained approximate results. We use in the different environments in daily use, so caused the time differences.

3 Why does my laptop only charge to 99%?

In a notebook battery usually within a control circuit for the values of the laptop power, when the recording data of the control circuit is different from the battery status itself, the battery may have been unable to reach the control circuit record, which is in fact the battery has been full, the problem can usually be resolved by correction, there is no effect for the normal use if you don’t do it, protection circuit will be disconnected automatically after a long charging time that can not be filled, to avoid overcharge the battery.

4 Can we manually change our own batteries?

In principle, do not replacement batteries by yourselves, firstly destroy the warranty, and secondly, many manufacturers’ battery protection circuit is designed to become a self-locking forms, once the batteries left control circuit, the circuit will be self-locking, so that if the control circuit failure, the entire battery is facing obsolescence. Furthermore, at present high-quality batteries are hard to buy, the life time will not be much improved after replace.
