Did not write this...... but its funny

blah, blah, blah, blay, blah, blah~!!!! plug it in and use it. once in a while let the battery drain all the way down. then plug back in, and use normally. most laptops are plugged in more times than not. so it will charge while you use the computer plugged in. that's it.

It doesn't need to charge repeat 3 times. li-ion battery has very little memory effect.

You can use it directly, I found a good place buy the replacement ASUS G74SX battery:
