take up to four (4) hours to complete the recovery process and will return to Standby when completed. CAUTION. USE THIS MODE WITH CARE. THIS MODE IS FOR 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. Using Supply.

Connecting to the Battery. Do not connect the AC power plug until all other connections are made. Identify the correct polarity of the battery terminals on the battery. The positive battery terminal is typically marked by these letters or symbol (POS,P,+). The negative battery terminal is typically marked by these letters or symbol (NEG,N,-). Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts. The below instructions are for a negative ground system (most common).

Understanding Charge LEDs. The charger has four (4) Charge LEDs per bank - 25%, 50%, 75% and 100%. These Charge LEDs indicate the connected battery(s) state-of-charge (SOC). See the explanation below: LED Explanation 25% LED The 25% Charge LED will be “on” when the battery is less than 25% fully charged. The RED charging LEDs will “spin” indicating the unit is charging. 50% LED The 50% Charge LED will be “on” when the battery is less than 50% fully charged.

Charging Steps. Step 1 & 2: Analyze & Diagnose Checks the battery’s initial condition, including voltage, state-of-charge and health, to determine if the battery is stable before charging. Step 3: Recovery Initializes the Recovery desulfation process (if needed) for deeply discharged or sulfated batteries by pulsing small amounts of current. Step 4: Initialize Starts the charging process with a gentle (soft) charge.
