Can you usually expect to find BETTER replacement batteries for most models, or are you usually pretty much stuck with whatever was designed to work with the laptop?
I ask because I'm looking into getting a used Dell Inspiron 9400 E1705, but its average battery life is only 2 hours. The similar 1520 laptop lasts 3 hours (but smaller screen), so I'm trying to figure out if you can buy better batteries for whatever laptop.
So far, I can't find any on Google, but then again, it's hard to tell, because none say: "Lasts X amount of time". I think they measure in mAh, or volts, or cells, or something. See, the default battery for the Dell E1705 laptop is 6-cell, but this here is 9 cell, and I don't know what that means. I'm guessing it adds the extra hour, but I'm a laptop-battery noob.
Oh, and what kind of life-span can you *generally* expect these batteries to have? Are we talking hundreds of charges, or thousands? I've never stressed a laptop battery enough to be able to tell.
