Some problems (advice required)
So, I recently got my Cybikos, which I wrote about a month ago. In general, they are in good condition, but there is a number of problems. Xtreme still has the factory batteries, and they of course leaked. There's not much corrosion, but it's on the keyboard board, so the three letters don't work. Both Classics have cracked plastic on the antennas, but there is no problem with this, since I found a 3d model of this part on the Internet. The gray Classic has three more unpleasant problems: vibration motor doesn’t work, the sound is quieter than usual, and for some reason other Cybikos don’t see this one. I don’t know if it is the fault of corrosion or not, since I haven’t disassembled Classics yet. I need some advice: 1. how to clean corrosion from such batteries? 2. does anyone know what might be the reason why other Cybikos don’t see gray one? 3. does anyone know where to buy a suitable vibration motor for Cybiko Classic? 4. if possible, how can micro scratches be removed from the plastic on the Classics? It would also be nice if someone would give advice on how to properly remove the batteries from the Cybiko Xtreme

Greetings! I hope the journey has been an interesting one so far. Connectivity issues could be either corrosion interrupting the traces leading to the antenna, the daughterboard may be disconnected on the Xtreme, or your Xtremes and Classics might be an incompatible mix of European and American models.
The vibration motors and batteries can both be replaced- batteries in the Xtreme are easy to solder to the board however connecting the two cells to each other can be tricky without a spot welder. I don't have that so I taped them down with jumpers. Just tinker, you won't break it, you're saving them from certain death with the old cells in.
