So i bought a couple of AW IMR 18350 3.7V 700mAh batteries but to use them in The Galileo i need a magnet (10mm dia x 2 mm), it should be placed inside the bottom cap, allowing the buttom to reach the battery and to make contact.
What i saw is although it had that magnet and i could use the 18350 battery, it would still fill loose inside The Galileo, because there is a small gap of about 1mm inside, so what i did is to place a small o-ring between the plastic piece that holds the screw that makes contact with the battery and the screw itself, like i show in the pics:
This is the top cap as it came:
I unscrewed the small aluminium screw, i got the little o-ring from a lighter:
I placed the little o-ring on the screw and install the screw back to the plastic piece:
Then i installed the top cap and the result was very good, the battery does not fill loose inside, the screw makes contact witht the atty adapter and the buttom fires ok.
