Pinebook (non-Pro) battery swollen - No complete start without it?

[guidol]

Yesterday I did start to install armbian trixie iot on my Pinebook.
Second part in debian - after the u-boot) starts, but then the Pinebook shuts off, because of a low battery(?)

I did charge the whole day and powered off in the evening.
 

Today the Pinebook stand on my table with a swollen battery. I removed it and happily it doesnt crash anything else than the battery holder.

 

But now it doenst boot up complete like with a low battery.

After the u-boot debian trixie does boot , but at the middle of the messages it does shutdown
Can it run completly without battery? I have normally a 5V/2Ah power-supply connected and that did work the last years.

 

Now I can only try to use a 5V/60W quick-charge Power-Supply.
Anyone has experiences with that?

Thanks for info in advance...
