Direct charge the battery when it not run out ， OK?

Many people have been asking all kinds of laptop batteries, I have answered many times, because of various problems are similar, so I order a bit, want to help users find the answer in question, hope the same problem we do not repeatedly asked me, in the paste in their answers.

First tell you a little knowledge: Comparison of advantages and disadvantages of various types of Dell Laptop Battery.

    Introduced the first rechargeable battery nickel-cadmium batteries (NiCd), but this battery has "memory effect", each charge must be discharged before, very easy to use, and soon it was nickel-metal hydride battery (NiMH) are replaced, NiMH is not only no "memory effect", and make more per unit weight of 10% of the electricity. The most commonly used battery is a lithium-ion battery (Li-Ion), it is also no "memory effect", compared with NiMH, get more weight per unit of electricity, the price twice as high than the NiMH. Blue notebooks are now using lithium batteries, S12A polymer lithium battery, volume control, and life in even better performance. In the same weight, the three battery time than is 1:1.2:1.9.

Question 1: Direct charge the battery when it not run out ， OK?

A: Most laptops use rechargeable batteries inside the lithium-ion battery (Li-Ion), no memory effect, you run out of power and not run out of charge is the same, do not worry. And buy something is to use, the notebook can play the largest role is the most important, considering the fear of damage to the battery can not charge contingency, that is the biggest loss.

Question 2: Why does my laptop battery will be useless broken a few times?

A: Many people have been inserted in the notebook battery notebook above, usually do not have life functions, a direct use of the adapter, this strange usage of the battery is not bad.

    Are there any battery life, Dell Inspiron i1764 Battery life, but according to charge and discharge cycles to be calculated. But many people do not fully understand this issue, coupled with the general number of notebook battery charge and discharge are at least 500 times or so, so many of my friends think that laptop battery life is about two years.

Laptop battery even if not, there will be self-discharge phenomenon, once place for too long, there will be excessive discharge situation. Once this level, I am afraid a lot of battery power are not on the charge, battery, hey, they come to an end a few useless.

In other words, even if you do not use the Dell Inspiron 1545 battery for a long time, not capable placed, preferably over a period of time on a charge and discharge, in order to maintain the battery's "state." However, because of lithium itself also has some memory effect (no memory effect Lithium generally say it is wrong, there are also memory effect of lithium, but it is small), preferably within the battery power runs out first, then charge, so The results will be better. Of course, the best control of the charging time of 12 hours, or over-charging can lead to reduced battery life.

    So remember usually at home, plug the power use, laptop batteries should be removed. There will not be used, as long as proper care, custody prior to discharge completely, not bad.
