How to keep your MBP battery healthy?

[Matt Cup]

Whats the best way to keep your battery at it's best? I've been given mixed info from a couple of people at the Apple store so I'm a bit confused.

1 - Fully charge and let it run out (rinse and repeat)
2 - Keep on power adapter and periodically run the battery down to <5% then charging it back up.

So any tips on how to look after my MBP battery would be appreciated.

I charge then use it on battery until its almost flat, and repeat.

used to keep on charge constantly but the battery started to suffer.

Do you also shut it down completely after use or just close the lid (sleep mode I think?)

Close the lid, don't think i have ever shut it down.

Mine always gets shutdown after use and I run the power right down and fully charge it each time.

Charge up to around 80% then run down to 20%. Once a month (or when I remember, which is usually the case) fully charge then fully drain.
