I tried to save money and it came back to bite me. The battery does not charge. My Dell Inspirion 1545 says plugged in not charging. It didn't work straight out of the package. VERY disappointing! Sadly, I even read the reviews of this happening to others and thought surely it wouldn't happen to me. How could someone sell a faulty item and get away with it? I so wish I had just bought a battery from Dell. I guess its time to read the return policy. I will update after I return it.
