Could the battery acid solution be too weak? I saw a problem once
when some of the original acid had been taken out of the batteries and
replaced by water. What does the voltage look like? In that
case, the voltage would never reach equalize voltage. <br><br>

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>
Thanks-<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>
<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>
Thanks-<br>
