I recently bought a new battery for my Dell Inspiron 1100 Laptop, my old one was barely holding a charge. When I got my new battery it wouldn't charge, so I asked for another battery from the company i bought it from. Well I just received my new battery and this battery is doing the same thing. When I look in my control panel and I open up my Power options, and then I go to my Power meter, I see that my battery is showing that it is not present. Although if I put my old battery back in, that shows up. Can anyone please help me and tell me what I am doing wrong? I need to know whether its my new batteries or not. When I compare my new batteries to my old one, the only difference is the Rating on my old batter is a 14.8V and my new on is 14.4v. Please any help would be great.
