Does the paper go back between batteries? Does the fist battery in go with - down and the second with - up?

The Negative (-) should face you, while the Possitive (+) faces the back cover. Both batteries go same direction. Therefore the - of the first battery should be touching the back of the second on the + side. The paper goes back the same as before.

That's incorrect. Many of these 2 battery Ford fob's have the batteries going in opposite each other. Follow the orientation on the paper, which does show opposite orientation between top and bottom, with paper between the two batteries.

Should I have to replace the battery on a 2017 Ford 3 months into 2018? I expected maybe every 3 years. Is there something I could be doing that drained it this quickly?

I've had the same problem and, although I drive little (only 3700 miles in the 9 months since I bought it), the notifications began about 3 months in and it finally gave up last week.

I thought that it could be due to having left the spare in the console for convenience in moving it around my "driveway/yard" and the less than 3 minute trip to my sister's house (where, of course, is where it died late at night and I'd accidentally left the other at home, haha?).

Did you by any chance do something similar? Maybe we just received some from an old/defective batch.

The Ford dealer told me when I bought my 2016 f150 not to leave the key fob in or close to the vehicle when not in use because it is constantly communicating with the vehicle and will wear out the batteries prematurely

For the 2015 mustang I had to put the paper back in between, bottom battery facing positive up, top battery negative up (like the picture on the paper shows)
