FYI, I haven't had to do this, just remember reading it in the manual. I've got the BMW branded version and it says something similar as I recall.
BATTERIES WITH "UNDER VOLTAGE PROTECTION"
Some Lithium-ion batteries have an on-board UVP (under volt-
age protection) that disconnects the battery to avoid it becom-
ing too deeply discharged. This prohibits the CTEK charger
from detecting that there’s a battery connected. To bypass this,
the battery charger needs to open the UVP.
By pressing the RESET-button for 10 seconds, the charger
opens the UVP. During this process, the charging STEP 7 is
lit. Once the UVP has been opened and the battery is ready
to be charged, the charger automatically starts the charging
cycle.

Yeah the CTEK manual says the same thing, same charger I think. I did that procedure like 29 times, LOL! Best I could get it up to was about 1.9V then it would discharge quickly. Battery reads 0.00V now.
