If you have been an owner of a laptop for long and have seen that the battery is not giving you adequate power then refilling them might be a good option. Original batteries are priced at above $100, but if you have some working skill then you can have a better battery by spending less than $50. The procedure goes by replacing the Li-ion cells and purchasing higher capacity cells than your laptop uses normally. Click here when you are ready. Thanks: Jay Via: makezine
