Ummm, I think you need to add run a normal battery charge cycle first to your list. Pretty dangerous to EQ a bank without doing bulk/absorb first, especially if you are at a clients house! You really do not know the state of the battery!

I performed the test I had promised to do. The answer is, add water first. Here is the report on my test: Link [4] Conclusion: Here is the proper order of steps to check Specific Gravity: 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. It seems obvious now, but I had to test it out...
