Now I can save money by reusing my batteries. I have been wanting to get a battery recharger for awhile now, so when I had the opportunity to receive this one it was perfect. All you do it place the rechargeable batteries into the docking station and plug it into the wall. The display shows you then when they are done charging and it's as simple as that. This is available on Amazon . I received this product at a discounted rate in exchange for a honest review.
