LITHIUM*
BATTERIES WITH "UNDER
VOLTAGE PROTECTION"
Some Lithium* 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
until the charge program is started and LED
steady light. Automatic "wake up" will be active for maximum
5 minutes.
If the charger is in Standby mode after 10 minutes ( power
led is flashing) the 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
the manual wake up is unsuccessful the power LED
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.
