Laptop battery correct charging and usage

Then call the user charging 12 hours is conducive to the use of the battery? In this good car emergency start power to give a negative answer, the current laptop battery has a sound power management circuit and charging management system, when the battery reaches saturation, The control circuit automatically switches to the short-circuit condition, so the later time is just a waste of time. How to activate the battery activity? In fact, manufacturers for the activation of the battery in the absence of overload protection of the battery charge and discharge for a long time. So, the first three charges 12 hours is not necessary.

Got a new battery, many users practice is in accordance with the tips of the business in the first three times the lithium battery to use for 12 hours or more. In this connection there are many online controversy, in fact, this is not necessary for the majority of laptop batteries. Why? Businesses say this is done to fully activate the battery activity, completely wake up the new battery.

Sounds like this reason is very full and credible, but we have never thought about this issue. If, laptop battery has not been completely activated by the manufacturer to play, then such a product can be said to be just a semi-finished products. Impossible to ask every user to master the battery activation skills, in reality is impossible. Therefore, the battery has been fully activated by the manufacturer before leaving the factory.

Then call the user charge 12 hours is conducive to the use of the battery? Here I give a negative answer, the current laptop battery has a sound power management circuit and charging management system, when the battery reaches saturation, the control circuit automatically switches to Short-circuit condition, so the later time is just a waste of time only. How to activate the battery activity? In fact, manufacturers for the activation of the battery in the absence of overload protection of the battery charge and discharge for a long time. So, the first three charges 12 hours is not necessary.

At this time, many users are very confused in the use of the battery, after all, it should not wait until the battery is fully discharged before charging. In fact, the answer to this question should be like this, if you can do so is certainly a good thing, but the premise is that you do not bother. Of course, what I am saying here does not mean excessive discharge. Practice has proved that excessive discharge is absolutely harmful to the battery, which will shorten the service life of the battery.

So when the laptop prompts low power when it can be timely charged. Some businesses have repeatedly stated that there is no memory effect of their lithium batteries, this approach is extremely irresponsible. So when your battery is still more power or not to charge as well, because the memory effect does exist.

Third, the long-term unused batteries should be how to do, it is recommended that 40-50% into the charge, placed in a cool place at low temperatures, the following parameters can illustrate this problem.

Storage temperature 40% Charge status 100% Charge status

{0 degrees 98% (one year later) 94% (one year later)

25 degrees 96% (after one year) 80% (one year later)

[40 degrees 85% (one year later) 65% (one year later)

60 degrees 75% (after one year) 60% (after 3 months)

(Percentage is the percentage of the initial state of saturation)

Of course, it is best to use the battery out once a month, both to ensure a good battery state of preservation, but also not to completely drain the battery damage.

Fourthly, whether the practice of "using a full month of charge after one month's use" in the notebook's instructions is necessary. Lithium-ion laptop batteries generally have a management chip and charge control chip. Management chip which has a series of registers, there are capacity, temperature, ID, state of charge, the number of discharges and other values. These values will gradually change in use.

Angkor car emergency start power that in the laptop's instructions in the "one month after the full charge should be used" approach is the main role should be to correct these registers inappropriate value, making the battery charge control and nominal Capacity consistent with the actual situation of the battery. So this work can not be omitted, after all, expensive notebooks are still delicate aristocracy.
