    Love my laptop, but I only get about an hour of life out of my current battery. Any suggestions on a good upgrade?

    The current battery has the following specs:

    11.1 V 4.2AH
    4400mAh 48wh

    What is the key thing when looking to add length of charge? Is it the "4400mAh" I want to increase? Thank you!

    It does like this:
    4400mAh = 4.4Ah

    11.1V x 4.4Ah = 48,9Wh

    The last value is the most important. 11.V & 5200mAh will be roughly the same as 14,8V & 3900mAh so the final value in Wh is what should concern you.
