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.

Thank you John. Is anyone else out there seeing
specific gravity measurements outside of what
Trojan is stating on the spec sheets?
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)?

Sequoya, Wrenches,
Thank you for your patience on this, as I had no
easy Internet connection. Below are the clarifications requested.
ü Trojan Premium L16RE-B datasheet can be found
here:
<http://www.trojanbatteryre.com/PDF/datasheets/L16REB_TrojanRE_Data_Sheets.pdf>http://www.trojanbatteryre.com/PDF/datasheets/L16REB_TrojanRE_Data_Sheets.pdf
ü Trojan Premium line (
<http://www.trojanbatteryre.com/PDF/Premium_Trojan_ProductLineSheet.pdf>http://www.trojanbatteryre.com/PDF/Premium_Trojan_ProductLineSheet.pdf
) 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 .
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 Trojans 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.
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,
)
will have a nominal S.G. of 1.280 . Prior that, the nominal S.G. was 1,260.
I hope that helps,
John

Subject: [RE-wrenches] Trojan L-16 SG Readings- Did Something Change?
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 havent received
confirmation and wanted to know what data you all were seeing as well.
Thanks-
