I have a Dell Inspiron E1705 and i need a new battery because my current battery (6-cell 65 WHr) is dying.

What I would like to know is whether the 9-cell (80WHr) battery and the 6-cell (65 WHr) battery are different sizes. Is one bigger/thicker or do they look alike? Is the 9-cell battery bigger?

So if the 9-cell battery is inserted into my notebook, does it bulge or stick out at all or is it the same as the 6-cell (which i currently have)?

Thanks in advance!
so does it stick out in any dimension whatsoever??
I’m getting conflicting answers. does it bulge out half an inch or is it the same size? (I dont care about weight)
