Everywhere I see tips about notebook battery care, experts suggest, if you aren't using it, charge it to 40%, remove it from laptop and store in a safe place at room temperature in a plastic bag. Every 15 days, put it back in the computer, top it up to 40%, remove and store again. Every once in a while, exercise the battery by charging it to 100%, using your laptop unplugged until windows warns "plug in or i'll hibernate", plug in and charge to 40% again, shut down computer, remove battery and store.
I have this laptop for almost two years. It stays powered on about 14 hours every day, always plugged in. On occasions i use it unplugged, i get a whooping 6 hours of backup, even after two years (if all I'm doing is Firefox, with "power saver" profile and screen brightness set to 0. On Windows 8. Strangely, battery dies MUCH faster if I'm using windows 7 - 3.5 hours, performing the same Firefox browsing, i dual boot)
I have this software called "HP Battery Health Check" , came pre-installed with Windows 7, it shows here i have cycled the battery only 18 times in all these days. Always used it plugged in, and I get 6 hours of backup, with battery health at 100%.

So then, on laptops about two years old or newer, is it at all needed to remove the battery while plugged in? Of course, my personal experience lets me strongly believe it isn't, nevertheless, what do you people think? Is this an exceptional case? or is this true for all present laptops and removing the battery is just a waste of time.

Removing the battery is about more than the health of the battery.

If you leave your battery in and the charger plugged in always then you end up with motherboard and charging system damage after a time. It can essentially ruin your computer.
As for the battery itself, the remove it or else thing kind of went out with nickel cadmium batteries. Lithium Ion does not have a charge memory like the older ones do.
 
I use my laptop a lot more than I used to. I normally always have it plugged in at work, though there are days I run it straight off battery. I got the 9-cell battery and I got around 6 hours of life when it was new. I follow the practice of not letting the battery drop below 15% before I charge it again. Four years later and I still get around 3 hours of battery life.
 
I have my battery always installed on my laptop, plugged or unplugged and it still works fine even after 2 years.
 
I have a 5 year old Dell Inspiron laptop that has been plugged in for about 90% of the time I've had it with the battery installed and it still works fine. The batteries used in laptops have a finite lifetime and they will all fail eventually regardless.

I've owned quite a few laptops/netbooks/phones/tablets etc... with rechargeable batteries and have never worried about coddling the batteries in them and have always gotten good life out of them.
