Should I drain and recharge a Lithium Ion battery?

Hello, I just purchased this:

http://r.ebay.com/k7Nbn1

It says it's Lithium Ion, and that I should use it completely, recharge it fully, and repeat this 3-5 times.  I read elsewhere, though, that LI batteries don't need this.  Your thoughts?

The advice on Ebay is mirrored here

However I can't guarantee that the Ebay and the link are both accurate.  However the dealer selling it should know how his product works ...

Anyway that cyciing shouldn't hurt the product (battery).  After that the recommended advice I've read (from Apple) is to keep the charge between 60 and 80% for the longest life in the battery.  No need to go to 100% or to fully discharge the battery.

There are lots of links on the Internet on how to care for your battery.  And most of them disagree in some form or another.
These folks know a little about the technology.

Although I stated 50%-60% for the "happy" zone they state 40% for storage.  I would take their word.
