Electrical energy would not be used up regarding offer notebook battery power asking

Many people have asked the laptop battery problems, because the problems are more similar, so I put together, can help you "books family

First to tell you a little knowledge: all kinds of laptop batteries pros and cons contrast
  
The first launch of the rechargeable Dell Latitude E6500 Battery is a nickel-cadmium battery (NiCd), each must be discharged before charging, very easy to use, but the battery has a "memory effect", soon to be replaced by the nickel-metal hydride batteries (NiMH), NiMH not only There is no "memory effect", and weight per unit can provide 10% more power. The most commonly used battery is a lithium-ion battery (Li-Ion), it also does not have the "memory effect", compared with NiMH obtain more power per unit weight, the price is twice as high than the NiMH. Laptop lithium battery, volume control, and battery life performance even better. In the same weight, the use of three battery is 1:1.2:1.9 ratio.

Question 1: The battery inside the power more than have not run out direct charging, OK?

A: Most of the rechargeable batteries used in notebook inside the lithium-ion battery (Li-Ion), no memory effect, you run out of power and did not run out of recharge are the same, and do not have to worry about. Bought thing in order to use, can play notebook role is the most important, because the fear of damage to the battery and can not emergency charging, that is the biggest loss.

Question 2: Why does not my laptop battery a few useless will be broken?

A: many people notebook battery has been inserted in the books above, usually do not have a life function, one directly on the adapter, this usage strange if the battery is not bad.
  
All batteries are the life of the Dell Latitude D630 Battery life, but calculated according to the number of charge and discharge. But a lot of people on this issue is not very understanding, plus the general notebook batteries charge and discharge times at least, so many of my friends also about 500 times that notebook battery life is about two years.

Laptop even without the battery will self-discharge phenomenon occurs once place for too long, it will discharge excessive. To this extent, a lot of battery even the electricity charge is not on, hey battery useless several times come to an end.

In other words, even if your battery is not in use for a long time, not capable placed, preferably over a period of time to carry out a charge and discharge, in order to keep the battery "state". However, because the lithium certain memory effect (generally say lithium no memory effect is wrong, the lithium in fact memory effect, only a small only), it is best to first electricity within the battery runs out, and then charging so The effect will be better. Of course, charging time is best controlled in less than 12 hours, otherwise the the excessive charge will result in the reduction of the battery life.
  
So remember usually at home, plug power use, you should remove the laptop battery. There are long-term use, as long as the custody properly custody prior to discharge completely, not bad.

Question 3: Why are 6-cell 4400 mA battery, some 3 hours, some a movie are endless, what is going on.

A: In addition to reduced Dell Vostro 1520 Battery life itself, the power consumption of the notebook itself is the key to affecting battery life certainly better than watching a movie costs of electricity, play 3D games, watching movies certainly than text processing costs of electricity, turn on the wireless certainly better than without wireless costs of electricity, of course, the CPU and graphics power design is also very important.
  
Take my tassel version N80H84VN-SL, Asus notebook, because of the use of the Intel Core Duo P8400 processor (ie low voltage processors for consumer-level notebook market), very low power consumption, immediately in the case of the use of wireless Internet 3 hours is not a problem; same open wireless access to the Internet, with up to two and a half hours; play 3D games, two hours less than no electricity.


Question 4: buy a new notebook, be sure to charge more than 12 hours? Usually charge indicator jump into the green, there is a need to continue to charge it?

A: everyone to buy books, general sales or technical staff will take care of the books, must buy a new battery is all used up, and then in the off state, continuous charging more than 12 hours, repeated three times to ensure that after the battery's normal to use. (Like selling the phone will say)

        In fact, this argument is untenable. Now books inside the Dell WU946 Battery are loaded overcurrent protection function, that is to say, when the probe into the books of the battery has been fully charged, it will automatically switch to the overload protection mode (see the charge indicator jump into the green from red ). In this mode, the battery has stopped charging power adapter (charger) just played the role of conducting speak simple point is inserted electricity, but got nothing dry. So, buy a new notebook, in the off state, charged up to the lights switched to green, and then skip the multi-charge time. Usual charging indicator as long as the switch to green, there is no need to continue to continue to charge.
