Thinkpad x270 battery died after sleep

Hello! I have encountered a problem with my x270. I've left my laptop asleep (suspend to ram) and disconnected from power for about 4 or 5 days.

Obviously this has drained the power from both batteries and I've lost all the data in RAM.
Unfortunately, my external battery stopped working after this.

 

My internal battery has charged since then and is working ok

Is there anything that I can do to recover the battery? I have tried powering down/up the laptop and leaving it turned off and plugged in over night. And moreover, will I kill the new battery when I forget my laptop asleep the next time?

 

PS. I am running gentoo linux if that matters
