>> 1. Verify water level in cells is above the moss-guard. Add water only to bring water to top of moss-guard if needed.

>> 2. Run Equalizing charge.

>> 3. Add distilled water to all cells to bring electrolyte to recommended level.
>> 
>> 4. Apply bulk charge voltage to batteries for 30 minutes to mix electrolyte.

>> 5. Test and record Specific Gravity.
