Does anyone know how much an extra Laptop battery cost? And how do i find one for my Laptop specifically? My new Laptop has terrible battery life, and the best solution i can think of is to buy a spare battery. However. i have no experience, or knowledge about this sort thing. I know that i have to find a battery specifically made fro my Laptop, but where do i find it. There was nothing on eBay, or Amazon. I am lost at the moment. Any advice would be appreciated.
