<p class="MsoNormal" style="margin-left:.25in"><strong><i>2. Can I use the specific gravities to troubleshoot my battery?</i></strong><b><i><br>
</i></b><i>The specific gravities of batteries are an excellent tool to determine the state of charge of batteries and their ability to accept a charge. Unfortunately, the specific gravities can also lead to an erroneous conclusion if we do not specify the
conditions under which the measurements were taken. The two major sources of error in measuring specific gravities are lack of temperature compensation and water addition. Since the specific gravities of batteries are affected by temperature, the measurements
must be temperature compensated. The best way to compensate for cold temperatures is to subtract four points from your reading for every 10º F (5.5º C) degrees below 80º F (27º C). To compensate for hot temperatures simply add four points from your reading
for every 10º F (5.5º C) degrees above 80º F (27º C). Also, the addition of water should only be done once the batteries are fully charged as the electrolyte levels vary as a function of state of charge and are highest once the batteries are fully charged.
Please use-distilled water only and note that adding water will lower the specific gravities of your batteries. The specific gravities cannot be used as a reliable source unless we account for the two sources of error mentioned above.<o:p></o:p></i></p>

Thank you John. Is anyone else out there seeing specific gravity measurements outside of what Trojan is stating on the spec sheets?
<br>
<br>
John, we are not seeing these SG readings, no matter how much we equalize, we are still seeing readings that are about .015+/- low after several equalizations. This is on newer batteries, and within the plate forming period. Do you have a SG reading that we
should be looking for during the first 18 months (or XX amount of cycles until the plates are properly formed)?<br>
<br>

<br>
Sequoya, Wrenches,<br>
<br>
Thank you for your patience on this, as I had no easy Internet connection. Below are the clarifications requested.
<br>
<br>
<br>
ü Trojan Premium L16RE-B datasheet can be found here: <a href="http://www.trojanbatteryre.com/PDF/datasheets/L16REB_TrojanRE_Data_Sheets.pdf">
http://www.trojanbatteryre.com/PDF/datasheets/L16REB_TrojanRE_Data_Sheets.pdf</a>
<br>
<br>
ü Trojan Premium line ( <a href="http://www.trojanbatteryre.com/PDF/Premium_Trojan_ProductLineSheet.pdf">
http://www.trojanbatteryre.com/PDF/Premium_Trojan_ProductLineSheet.pdf</a> ) has indeed changed its specific gravity from nominal 1.260+-0.007 to nominal 1,280+-0.007 since March 2012 production. This change was motivated to reduce the confusion in the
field between Trojan Premium line S.G. values and Trojan Signature line S.G. values. They are now identical. Only Trojan IND line S.G. remain at 1.260 .<br>
<br>
ü During the beginning of the life of the battery, an optimized development process of the plates porosity will take place to maximize the surface access contact between the electrolyte and the lead sulfate crystal within Trojan proprietary exclusive paste
formulation. This optimum moisture of the active material at the beginning of the battery life is the continuation of an advanced factory-controlled 72-hour curing process and increase the electrical conductivity and improved discharge performance of the
active material paste, resulting in Trojan’s proven both sustained capacity and total overall ampere-hours, resulting in more operating power. The variation can reflect approximately 7 points in the S.G.
<br>
<br>
ü The date code can be found on the negative terminal and consist of one letter and one figure. The figure for 2012 is “2”. Any date code from and after “E2” (i.e. Code date with letter E2, F2, G2,…)<br>
will have a nominal S.G. of 1.280 . Prior that, the nominal S.G. was 1,260.<br>
<br>
I hope that helps,<br>

<b>Subject:</b> [RE-wrenches] Trojan L-16 SG Readings- Did Something Change?<br>
<br>
We are wondering if anybody knows when the Trojan L-16RE-B batteries went from full SG readings of 1.265 (after an 18 month "plate forming" period) to 1.280 that they now state on the data sheet. We have been having customers use 1.250 as a full reading which
would gradually increase over time to 1.265 and that might take/might not be seen for 18 months. Now we see that a "full reading" should be 1.280 and maybe still a "plate forming" period or maybe not? Does anyone know the date code that we can use with customers
to see what they should be looking for (should have been somewhere between 2010 and 2012)? I have this question out to Trojan as well, but haven’t received confirmation and wanted to know what data you all were seeing as well.<br>
<br>
