Using Repair Modes. [From Standby Press and Hold 3 Seconds While Connected to the Battery]
Repair is an advanced battery recovery mode for repairing and storing, old, idle, damaged, stratified or sulfated batteries. Not all batteries can be
recovered. Batteries tend to become damaged if kept at a low charge and/or never given the opportunity to receive a full charge. The most common battery
problems are battery sulfation and stratification. Both battery sulfation and stratification will artificially raise the open circuit voltage of the battery, causing
the battery to appear fully charged, while providing low capacity. Use Repair in attempt to reverse these problems. For optimal results, take the battery
through a full charge cycle, bringing the battery to full charge, before using this mode. Repair Mode can take up to four (4) hours to complete the recovery
process and will return to Standby when completed. Repeated repair cycles may be needed depending on size and condition of the battery, however battery
temperature must be closely monitored.
CAUTION. USE THIS MODE WITH CARE. THIS MODE IS FOR 6-VOLT, 12-VOLT AND 24-VOLT LEAD-ACID BATTERIES ONLY. THIS MODE USES A HIGH
CHARGING VOLTAGE AND MAY CAUSE SOME WATER LOSS IN WET (FLOODED) CELL BATTERIES. BE ADVISED, SOME BATTERIES AND ELECTRONICS
MAY BE SENSITIVE TO HIGH CHARGING VOLTAGES. TO MINIMIZE RISKS TO ELECTRONICS, DISCONNECT THE BATTERY BEFORE USING THIS MODE.

EN

the charger to detect, press and hold the mode button for 5 seconds to activate Force Mode, then select the appropriate mode. All available modes will
flash. Once a charge mode is selected, the Charge LEDs and the selected mode LED will alternate between each other, indicating Force Mode is active.
After five (5) minutes the charger will return to the normal charge operation and low voltage detection will be reactivated.
CAUTION. USE THIS MODE WITH EXTREME CARE. FORCE MODE DISABLES SAFETY FEATURES AND LIVE POWER IS PRESENT AT THE CONNECTORS.
ENSURE ALL CONNECTIONS ARE MADE PRIOR TO ENTERING FORCE MODE, AND DO NOT TOUCH CONNECTIONS TOGETHER. RISK OF SPARKS, FIRE,
EXPLOSION, PROPERTY DAMAGE, INJURY, AND DEATH.
