<p>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!</p>

<p class="MsoNormal"><span style="font-size: 12.0pt;">If you recall, I had asked the question: After equalizing batteries, should I check SG before or after watering? I performed the test I had promised to do. The answer is, add water first.</span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;">Here is the report on my test: <a href="https://millersolar.com/MillerSolar/case_studies/26%20Specific_Graviity/Specific_Gravity.html">Link</a></span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;">Conclusion: Here is the proper order of steps to check Specific Gravity:</span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;">1. Verify water level in cells is above the moss-guard. Add water only to bring water to top of moss-guard if needed.</span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;">2. Run Equalizing charge.</span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;">3. Add distilled water to all cells to bring electrolyte to recommended level. </span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;">4. Apply bulk charge voltage to batteries for 30 minutes to mix electrolyte.</span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;">5. Test and record Specific Gravity.</span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;">It seems obvious now, but I had to test it out...</span></p>
