dell laptop battery

And I got to thinking, as I, the battery life of the unit over the years may receive as well.

From my sister I know that you can blow up the battery and its performance quite quickly – just keeps charging the Dell Inspiron 6400 battery of the laptop, even if he is not really empty (also at 90%). So almost always leave the battery in it, even if the device is a long time on the net.
So they did with their first unit, the unit’s reaction: within the shortest time decreased the battery life per battery charged (100%) dramatically, from about 3-4 hours were 1.5. The same I believe I have recognized in my old Casio digital camera. Also there is the concept of memory effect, which should be eliminated even by modern batteries. But something like that then it’s got to be even with the modern battery when the described phenomenon can be observed.

So, I thought to myself, but I do it differently: If the laptop is attached to the mains, the DELL XPS M1330 battery is removed at the same time – unless this is actually empty and should be charged for an extended mobile use.

I also informed only on advice of an acquaintance, a charge the Dell Inspiron 1720 battery on the Internet. Here it is, this survives to 500 charging cycles (one cycle is therefore the charge load from 0 to 100%), only then he loses noticeably in performance.

So, unpacked so the other night at my friend the laptop battery out, as a network operation was planned – and already I’m looked at from this angle: “What should I bring”, he asks me. My reasoning was as described above. However, he said, “had 500 charge cycles much as from 0 to 100″ “is” settled, and “I could safely leave the battery in the device.” Moreover, “the battery from 100% anyway would not be charged if the same device on the network,” which I believe, however, not entirely accurate. And also “the contacts of the battery faster so the mind would give up when the battery power itself.”

Now my two questions to the whole subject:

1st Am I right when I remove the Dell Studio 1735 battery if it is not just empty and will hang the device over a longer time on the network?

2nd Is really no energy / power / … drawn from the battery when it is fully charged at 100%, that is? Here I was thinking that it is possible without problems to pull the plug, the laptop now runs automatically continue at the expense of the Dell Studio 1555 battery. Is such a sudden change, without ever at least a fraction of the battery is used, does it make?

How did you handle your laptop and the battery? Do you have similar experiences?
