Generally speaking, if you find that the batteries test reading are a little low, they are probably just a little discharged. After recharging the batteries, test them again. If those readings are low, then contact the manufacturer with the data. I have had great luck with battery manufacturers warranting their defective batteries in warranty.<br><div> </div>Nick Soleil<br>Project Manager<br>Advanced Alternative Energy Solutions, LLC<br>PO Box 657<br>Petaluma, CA 94953<br>Cell: 707-321-2937<br>Office: 707-789-9537<br>Fax: 707-769-9037<div><br></div><div style="font-family: arial,helvetica,sans-serif; font-size: 12pt;"><br><div style="font-family: times new

I'm curious of others experiences with testing "new" batteries right from the mfgr, before putting them into service. I'm not talking about load testing, i mean just basics...voltage, specific gravity and electrolyte level.<div><br></div><div>I recently received some batteries (24 x 2V) and before putting them to work i tested all the voltages, SG's and levels. Voltages were all with-in 0.016 V (2.1-2.084). The SG's were within 0.037 (1.281-1.244). Yes, the one with the lowest SG also had the lowest V. </div><div><br></div><div>What concerns me a bit more than the few cells with lower SG is the consistent low levels of electrolyte. All cells were between 3/4" and 1-1/2" below full, which is 1/4" below the bottom of the vent well tube.... with one exception that was bang-on full. Interestingly, the one full battery was the only one with a different date code than the rest. </div><div><br></div><div>Should the
various levels of electrolyte mentioned be acceptable when a battery is brand new, straight from the mfgr? How bout the SG's?</div><div><br></div><div>I'm considering adding electrolyte from a local battery shop instead of distilled water to top up all the batteries. Comments?</div><div><br></div><div>Very thankful for the wealth of knowledge and experience on this list,</div><div>benn<br><br><span class="ecxecxecxecxEC_Apple-style-span" style="color: rgb(0, 32, 96);"><font class="ecxApple-style-span" face="'Franklin Gothic Medium'">DayStar Renewable Energy Inc. </font></span><div><div><font class="ecxApple-style-span" face="'Franklin Gothic Medium'">benn@daystarsolar.ca</font></div><div><font class="ecxApple-style-span" face="'Franklin Gothic Medium'">780-906-7807 </font></div><div><font class="ecxApple-style-span" face="'Franklin Gothic Medium'">HAVE A SUNNY DAY
