Ta for the pics! I just magaed to pour tea in mine ... grrr! seems mostly working, but keyboard partly not.. how did you get the battery out? mine won't bude
I didn't. The picture without a battery is from inside the top cover (screen part of the Gemini) while the picture with the battery is from inside the bottom cover (keyboard part of the Gemini).
This thread:
[a href=\'index.php?showtopic=34856\']www.oesf.org/forum/index.php?showtopic=34856[/a] seems to suggest there no easy way to remove the battery. Due to space constraints, it's not designed to be removable, but replacable (when worn out). This seems to mean it's connected to the Gemini via a proper connector, rather than just being soldered in, but the battery itself is still (my guess) likely held in place by some adhesive.
Unless already done, I'd suggest carefully removing the key caps and keyboard mat, and try to clean things up the best you can. The keycaps are designed such that they can be removed, but they are a bit delicate. Gently prying from the rear seems least likely to cause damage. You can look at the pinned topic on keyboard mat replacement. Doing this sooner than later will likely reduce risk of liquid damage by corrosion.
Should that not work out, I guess you'll have to ask Planet Computers for help. The thread linked above mentions Planet Computers setting up a repair facility. As that post was from late March, perhaps it will soon be in operation. Best of luck.
Edit: Looking inside the battery compartment, I can see some holes through which the bottom of some of the keycaps are visible:

(There are more to the right, which aren't visible in this closeup.)
At least for those key locations, having access both from the top (after removing keycaps) and the bottom, might somehow facilitate cleaning. Again, best of luck.
Edit #2, Sep 2 2019: To avoid bumping a basically archived thread, I'm adding a link here to a picture I came across:
[img]https://regmedia.co.uk/2017/09/10/board_l.jpg\" border=\"0\" class=\"linked-image\" /]
It comes from this
https://www.theregister.co.uk/2017/09/11/ge...ototype_handson 2017 article on the then upcoming Gemini. As it shows a [prototype] main board from a different angle than the picture below from zevv, I thought should be included here. The article itself has a few more old photos, including one of a keyboard with the (later ditched) rectangular Enter key.
