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
charger from detecting that there's a battery connected. To bypass this, the battery
charger needs to open the UVP. There are two options available to "wake up" the
battery - automatic and manual.
During the automatic "wake up" period the LED
is started and LED is lit with a steady light. Automatic "wake up" will be active for
maximum 5 minutes.
If the charger is in Standby mode after 10 minutes (
automatic wake up did not succeed. Try the manual wake up.
To use the manual "wake up", press the Mode button for approximately 10 seconds
to bypass the UVP. During the "wake up" period the LED
program is started and the LED is lit with a steady light. If the manual wake up is
unsuccessful the power LED will start to flash after latest 10 minutes. Disconnect any
parallel loads from the battery and try again. If the charging does not start after that, the
battery may need to be replaced.
