I think the extender battery kicks in automatically. Every i time i use my laptop basically i plug it in. Don't ask why. I just do it for the heck of it. Not to run out and have to plug it in again.

The best thing to do is use it until goes dead and then recharge. If you ask me it ain't a good idea to leave the charger plugged in knowing that it's fully charged.

You just have to cycle the battery once a month.  You can leave it charged in all the time, but at least once (or maybe twice) a month drain it down to at least 10% and then recharge it again.  It just refreshes all the cells in the battery.

If you know you are not going to use the battery for an extended period of time, remove it and store it in a temperature controlled, dry environment.  Also, do not store the battery fully charged, as this may cause damage to it.  Run it down 50% and then store it.  

Do this and that battery should last for years.

You didn't mention a brand, but the information is readily transferable to other makes/models of laptop: Apple's guide to caring for the batteries in their laptops (MacBook, MacBook Pro) -- <http://support.apple.com/kb/HT1490>

Basically, as others have said, you want to periodically (at least once a month) let the battery drain down until the computer shuts off and then either remove the battery and run off wall/AC power or set the computer aside (turned off entirely) for 5 hours (per Apple's recommendations; it may vary by battery capacity/chemistry as to how long to let it "rest".) After that, charge it up to full power and you can use it as usual, plugged in to wall/AC power if desired once fully charged.

More info (from Apple, but same should apply for other models) about laptop lithium ion batteries) --
