BATTERIES WITH "UNDER VOLTAGE PROTECTION"
Some Lithium-ion batteries have an on-board UVP (under voltage protection) that
disconnects the battery to avoid it becoming too deeply discharged. This prohibits the
CTEK charger from detecting that there's a battery connected. To bypass this, the bat-
tery 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.
