OK--so my sister-in-law desperately needs a new laptop battery for her Dell Inspiron E1505. Just found one at a GREAT price on amazon (so I know I have some sort of guarantee and I can return defective items) BUT after doing some research, I see some people LOVE the cheap batteries, and some people HATE them. Now, I remember a time when Dell was so anal about making sure that everything that was done on a Dell pc must be done with Dell products. Is this true about the batteries? Like I said, I've found some great reviews, and some reviews stating that the battery wasn't read by the Dell lappy, and after some short period of time, it stopped charging the battery at all because it was not by Dell. Any advice is highly appreciated. Also, we are trying our best to avoid any trial and errors here. My sister-in-law doesn't live close-by and she is not computer savvy so we just want to make this a one-time simple transaction. In addition...money IS an issue here and we are trying to keep costs down. Thanks!!
