Charging
Automatic multi-stage charging and real time diagnostic allow
fast recharge and recovery of deep discharged batteries, adding
value and reliability to the system hosting. Type of charging is
Voltages and current stabilized IUoUo. The state of charging
battery and Autodiagnosis of the systems are identified by a
flashing code on a Diagnosis LED and Fault Battery LED:
