4) Absorption Charging Stage 1
Uses a constant voltage of 14V while reducing the charging output current to ensure the battery
receives approximately 90% charge without overcharging the battery.
5) Absorption Charging Stage 2
Steps up the constant voltage to 14.4V while reducing the charging output current to ensure the
battery receives a full charge without overcharging the battery.
6) Full
Once the battery is fully charged, the Green Full LED will come on. The charger output will stop.
However it will continue to monitor the battery condition as it will enter Long Term Analysis
mode.
7) Long Term Analysis
During long term analysis mode, the charger will monitor the battery level and reactivate the
charger output if the voltage drops below 12.9V to ensure the battery is always ready when you
need it.
Century Batteries does not recommend leaving the battery charger connected for more than 24
hours during LITHIUM (LFP) Mode. Disconnect after 24 hour use.
LFP Wake Up - Power Supply - 13.8V 12A Max (1A, 8A, 12A selectable)
If the Lithium Activation signal isn’t waking up your battery BMS you may use this feature to wake
it up. With the LITHIUM (LFP) Battery Type selected, press and hold the MODE button for 3 seconds
until the LFP Wake Up - Power Supply LED turns ON (Green). The unit will output 13.8V and force the
BMS to wake up and the battery will start accepting charge. After a few minutes you can then press
and hold the MODE button for 3 seconds to exit LFP Wake Up - Power Supply mode and unit will
revert back to charging mode.
This mode is time limited and will automatically switch back to LITHIUM (LFP) charging mode after 24
hours.
STEP 4 - Disconnecting the Battery charger from Battery
•
If the Battery is out of the vehicle:
(1) Switch OFF and Remove the AC Power Socket from the outlet.
(2) Remove the Black lead and then the Red lead.
•
If the battery is still in the vehicle:
(1) Switch OFF and Remove the AC Power Socket from the outlet.
(2) Remove the lead from the vehicle chassis.
(3) Remove the lead from the battery.
Note: Check electrolyte levels if possible after charging as they may need topping up with distilled
water. (This does not apply to Sealed Maintenance Free batteries and Lithium type batteries)
