Do not use the battery charger to charge the batteries of other vehicles; the battery
charger installed was specially designed to charge the type of lithium batteries used
on this machine. Do not attempt to charge any other type of batteries.
•
Do not attempt to repair the battery charger. Opening the cover may expose the
user to the risk of electric shock.
•
Do not open battery charger, opening it may affect the index of protection (IP) even
after it has been closed again.
•
If battery charger is not working correctly or is damaged, disconnect it immediately
from power outlet and the battery socket and contact a qualified JLG equipment
mechanic.

Charging Phases
The battery charger features four charging phases, designed specifically for charging the
lithium-ion battery pack on this machine.
•
Bulk Charge Phase - 0% charge to 90-95% charge. First phase of charging a
depleted battery. Provides constant current and constant voltage.
•
Equalization Phase - 95% charge to 100% charge. Towards the end of the charging
process the BMS detects which cells are fully charged and switches to constant
voltage. The BMS then controls the charge current to cells which need charging until
the charge level is equal across the full system.
•
Balancing Phase - Required to maintain the maximum available capacity. Provides
maximum capacity in the total battery pack, otherwise the capacity will be restricted
by the lowest cell on discharge.
Note: Recommended to be completed every time or at minimum after 20 charging
cycles.
•
Float Phase - Trickle charge the batteries. Helps further finely balance the cells.
