calibrate Dell XPS laptop battery

Specs: Windows 7, Core i5/8gig
I have a Dell XPS 15 L502z laptop and when I first got it, I charged the battery to 100% and then rebooted and entered the BIOS and then let it drain the battery to zero. I then charged it back up to 100% again and repeated this procedure 2 more times to properly calibrate the battery. Now, I have researched this procedure with some IT friends of mine and also looked on the Internet to see if I am following the correct steps to carry this out. I have heard varying opinions on this subject as far as taking it out of the laptop when I am not using it and having it charged to 50% of full charge. I always run it to less than 10% when I use the battery and then charge it back to 50-60% and take it out until next usage. By the way, the laptop specs are Core i5 cpu, 8gig ddr3 ram, Nvidia/Intel Optimus graphics, 500gig sata hd and intel wireless b/g/n. I want to care for the battery as it should be so that I can get maximum use of it in the future. Yeah, I know that on average, notebook batteries lose maximum performance after the first year and so on.... But I bought my first laptop in 2005 (amd athlon64 cpu, 1gig ddr ram, nvidia graphics, 80gig hd) and it lasted almost 5 years and I could still get 1.5 hours of battery usage in the end when taking care of the battery like I mentioned above. All opinions and replies greatly respected and appreciated.
Hope this is the correct forum for this...if not sorry. If I am neglecting to post pertinent info..let me know.

You are on the right track:

You have to be a little bit crazy to keep you from going insane.
