In Aliexpress if you type the number of the battery (actually it is your size) you will see a list of them, you should ask for the one that looks closest to the one you have. As the reception takes about 45 days I have provisionally put a battery of Samsumg (of a mobile phone) of 2,450 Ma. And it works perfectly. The opening of the Onyx is something more delicate, in my case you have to remove the 2 screws from the bottom and with a util (the triangle) to open the sides very carefully so as not to break any flanges. It is not difficult, but you have to be very careful. I'm sorry but I do not have time to make a video.
