THE CHARGING PROCESS: LITHIUM
1) Lithium Activation - Blue Charging LED Blinking
The charger sends a signal to wake up the Lithium battery management system (BMS) so it can
detect the battery voltage and commence charging if safe to do so.
Note:
If the Lithium Activation stage isn’t waking up the BMS (Blue charging LED isn’t coming
on), you can activate power supply mode on the unit by holding the Charge Rate Button down
for 3 seconds.
Important
: After around 1 minute, press and hold the Charge Rate button again
for 3 seconds to put the unit back into charging mode and the unit will commence charging.
2) Soft Start Charging - Blue Charging LED Flashing
Gently charges the battery using a reduced charge output until the battery voltages reaches
10V. If the battery voltage doesn’t reach 10V within 6 hours, the safety timer protection will
stop the unit from charging and the Charging, Full and Lithium LED’s will all flash.
3) Bulk Charging - Blue Charging LED ON
Uses the maximum selected charge output until the battery voltage reaches 14V.
If the battery voltage doesn’t reach 14V within 24 hours, the safety timer protection will stop the
unit from charging and the Charging, Full and Lithium LED’s will all flash.
4) Absorption Charging Stage 1 - Blue Charging LED ON and Green Full LED Flashing
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 - Blue Charging LED ON and Green Full LED Flashing
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) Float Mode - Full Green LED ON
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.
Long Term Analysis - Full Green LED ON
During long term analysis mode, the charger will monitor the battery level and reactivate the
charger output if the voltage drops below 12.8V to ensure the battery is always ready when you
need it.
STEP 5 - 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)
