Instruction Manual

4
To recharge a sulfated battery:
1. Attach the battery clamps as described in the instruction manual.
2. Always use the chargers lowest rate when turning the charger on. Set the charger to the chargers highest rate for the voltage of the battery
being charged.
CAUTION: NEVER CHARGE A BATTERY AT VOLTAGES RATES ABOVE THAT OF THE BATTERY.
3. The battery will show little or no amperage at the start of the charging process. This will continue until the sulfation begins to break down.
CAUTION: AS THE SULFATION BREAKS DOWN, THE AMPERAGE MAY RAPIDLY RISE. CONSTANT
ATTENTION MUST BE OBSERVED TO PREVENT SERIOUS OVERHEATING OF THE BATTERY.
4. Lower the charge rate to the lowest rate for the voltage of battery being charged.
5. Charge the battery at this low rate until the electrolyte reaches the fully charged state as described in the tables in your instruction manual.
This may take as long as two or three days.
NOTE: SOME BATTERIES MAY BE SO BADLY SULFATED THEY CAN NOT BE RESTORED TO A NORMAL OPERATING CONDITION,
REGARDLESS OF THE RATE OF CHARGE OR THE LENGTH OF TIME THE CHARGE IS APPLIED. IF THE BATTERY CANNOT BE
RESTORED TO A FULLY CHARGED CONDITION BY A SLOW CHARGING, IT SHOULD BE REPLACED.
