Sent my Asus notebook 6 cells battery for realt on 1st Nov 2008 Sat. Got it back the next day. Now the realt battery can last up to 4 hrs + of heavy internet usage via Wi-Fi, MP3 & Video
Battery Saving mode 249MHz = 4hrs 30mins
Quiet Office Mode 747MHz = 3hrs 15mins
It cost me RM180, compare to the original battery RM600+

Good customer service & value for money. Thumbs up!
