Do we need to calibrate the Playbook Battery like Macbook battery by completely drain the battery than leave it for 8 hours and charge it again?

Thanks

May be only every once in a while. Don't do that often though. Batteries don't like being fully discharged or being fully charged for too long too often.

The Battery Guru application is very handy to keep an eye on the battery health over a period of time.

Can be a good idea but no need to do intentionally. I will charge the Playbook whenever I can but there will be time when I dont have access to a charger and the Playbook will drain to Orange or even Red. Then I fully charge the device again.

I may be wrong but I don't think the battery needs calibrating. I think draining the battery would calibrate your battery meter(percent remaining).
You wouldn't hurt it by draining the battery but I wouldn't leave it for any extended period in a low voltage state. The PB will turn off before the battery gets to any dangerous level and leaving it for 8 hours shouldn't drain too much more but I don't see the need to leave it like that.
Unless you have an issue with your meter, it's not needed.

What they said. ;-)

Also note that the "percent remaining" indicator is what gets calibrated, and the OS will (should normally) do that automatically, over time. Doing a full drain can accelerate that, but it shouldn't be required.

What Chaddface is describing in his first sentence would best be called "conditioning" rather than calibrating, and Lithium-Ion batteries do NOT require any conditioning. That concept is for older battery technologies where it was actually required or useful.
