Dell battery compatibility

[1313]

Hey,

As my 6-cell battery doesn't last as long as I would like, I'm thinking of buying a spare. I can find a good deal on a 9-cell original Dell battery, there is just one problem: the guy bought it for his studio XPS and I've got a studio 1535.

I can't just try it out, it's not someone I know, but when browsing for replacement batteries on the Dell website, the batteries look alike even though they have different part numbers. Is this just Dell trying to scam you in buying exactly the same battery from them (but with another part number) just to be sure you got a compatible battery or is there really some technical restriction I need to worry about? Also, are batteries voor 17'' and 15'' versions bigger/smaller than their counterparts?

I don't know anything about batteries but it seems to me this must be no problem, am I right? Thanks in advance for clearing this up for me.

It looks to me that the Studio 153x and 155x all use the same battery, and the 164x all use the same battery. I don't think they're compatible; they look similar, but there are some small physical differences, which I believe would prevent them from being switched.

Hm, okay, not the answer I was hoping for but thanks anyway. Too bad they can't/won't produce interchangeable batteries but I guess that's just the way it goes these days.

The pictures aren't necessarily accurate. Use the model numbers as your main guideline.
