Laptop Battery Charging

After I posted the article by Kim Komando on smart phone charging, a friend read Kim's suggestions and posted his comments that it's OK to leave one's laptop plugged in all the time. This was contrary to Kim's suggestion.  After reading hi comments I did some research, and found this article which describes more about whether one should leave their laptop plugged in all the time or not:

Here is a quote from the article discussing whether one should leave a laptop plugged in all the time:

"Ultimately, it’s not clear which is worse for a battery. Leaving the battery at 100% capacity will decrease its lifespan, but running it through repeated discharge and recharge cycles will also decrease its lifespan. Basically, whatever you do, your battery will wear down and lose capacity. That’s just how batteries work. The real question is what makes it die more slowly.

Laptop manufacturers are all over the place on this. Apple used to advise against leaving MacBooks plugged in all the time, but their battery advice page no longer has this piece of advice on it. Some PC manufacturers say leaving a laptop plugged in all the time is fine, while others recommend against it with no apparent reason."

Here is the link to Apple's battery advice page:

Opinions vary on this question, so you'll need to decide which you prefer. As for me, I plan not to leave my laptop plugged in all the time. Laptops were designed to be portable and operate off their battery, then recharged when the battery gets low. For me, this is more convenient.
