I'm thinking of purchasing a Lenovo Y500, the only thing stopping me is the 3hr battery life. I'm also considering the option of getting a second battery if necessary and carrying it around.
Is that safe, carrying around a second lithium ion battery in your backpack? Do other people do this? Could it cause damage to the battery or laptop if I'm constantly swapping one battery out for the other?
