    I tend to leave the charger plugged in to my notebook and infrequently disconnect it when I move the machine. I have not run the battery down too many times in the past year, since I bought the notebook new. Is this bad for the battery and how does one optimize battery life?

    I would let it drain down to 20% or so every once in a while at least

    Thanks for reply. It has run down now and then. I'll let it do so more frequently and I should be OK.

    The battery needs "exercise".

    I'd suggest you disconnect it from charging power at least once a week (or twice).
    Let it run down to about 35-40%.
    Then re-connect it.

    Hang up a note -- "Tuesday is battery day".

    I let it run down completely after forgetting I had the thing unplugged. Would this significantly affect battery performance or longevity?

    I’m ashamed to admit that for the past twenty years I thought battery day was Thursday. ;)

    Nope - not a problem at all.
    You'll find a lot of comments on battery life. My family has probably had 10 or so Mac laptops in the past 10 years. One lasted 1000+ cycles (4.5 years - hardly plugged in) before the "Replace Battery" warning came on. Another was about 250 cycles (3.5 years - mostly plugged in). I've asked Apple Geniuses in several stores "How long should these last, and what can be done to make them last a long time?" The answer has always been 3-5 years, and don't keep them plugged in full time. Exercise them once in awhile.
