Charging Hub Red Light when plugging in battery

[Yaros]

Yesterday this happened to me:
I plugged in 2 batteries for charging, I come back later to check, one of them is completely charged, but the status LED on the Charging Hub is a dark Red color, and the other battery is not charging. I unplugged both batteries, restarted the charger, plugged the battery back in, and it started charging. Then the issue happened again, but when the battery was already completely charged.

Have anyone else experienced this? What does 'dark red' on the charging hub status LED mean?

Means battery error, could have just been not fully seated in.

Means battery error, could have just been not fully seated in.

Okay, thanks!
I hope that is the reason, because I don't want to replace a battery.

I experienced the same thing the other day then I noticed the charging plug to the cradle was not seated fully.
