Great Find!

Newer...corrected www link;

http://deltecpower.co.za/wp-content/uploads/2013/12/Deltec-Lead-Crystal-Batteries.pdf

Lifetime specifications on these are similar to Edison Iron/KOH batteries but with similar
electrical characteristics to acid/lead batteries.

Interesting new twist on salesmanship.

The SiO2 crystalline acidified "elecrolyte"
is in fact the Gel Cell or even the AGM
Cell.  They're "starved electrolyte" and
sealed (SLAB) lead acid batteries and thus
can have quite a long life.  They've been
around for a several decades

Dear OWCL,

So, OK thanks for the heads up.

When I went to the Chinese Company web site and the .pdf file for this product, it
completely lacks the data curves that the South African Company emphasized heavily.
So I can not tell if these refer to the same product of or not. I do believe that as
documented in the .pdf file that the Chinese have improved their product and that
it could now have specs shown on the South African web site. But I can not be sure
without further investigation.

Because acid/lead storage batteries are reaching a point of obsolescent relative to Lithium
Batteries this part is not really very important. I am simply interested in the acid/lead
battery chemistry for other reasons.

Seamonkey,

I think if one studies the cycle lifetimes vs depth of discharge curves for each battery
product it shows that the lifetimes are not nearly the same for identical products and
highly dependent on the average % depth of discharge. AGM batteries have nearly the
same curves as for flooded acid/lead. The touted Edison Iron/KOH batteries which are still
manufactured by the China, have graph curves are not that much better and very
similar to graphs presented for the lead/crystal batteries. 

We can not all of us have your experience with all the products we may want to use, so the
rest of us are going to have to rely on manufactures specification sheet data. As long as
you agree that there is a high and non-linear relationship of battery lifetime to cycle
count and % depth of discharge, I think we can agree. A unitary fixed lifetime rating
is only valid for a battery that is seldom/never used such as in a UPS application. Applications
in the alternative energy field such as a buffer battery for a house, this is almost never the case.
Battery arrays that require 3 to 4 times rated power just to improve their lifetimes cannot be
economically justified.

Lithium Batteries in the future will almost certain be and are now almost price competitive with
acid/lead for buffer applications.

MarkSCoffman,

Your comments are good and I quite agree.

Frankly, I'm a great fan of the Lead-Acid Battery
and use them almost exclusively.  When one
becomes well acquainted with their needs and
learns how to maintain them they can be
incredibly reliable.

The DELTEC Product Description is actually
quite informative if one reads it carefully paying
particular attention to the Q and A at the final
page.  It's ruggedized for deep cycle application
and does use some proprietary chemistry for
both the electrolyte solution and the plate
structures.  It seems to be a quality product
providing it isn't excessively priced.

Their use of "Lead Crystal" terminology as a
sales gimmick is a bit misleading.

Lithium battery technology will only have  a temporary short importance,
independant from really surprising success :

The  Lithium / earth habitants relationship shows us the restricted source limitation,recycling independant.


About the DELTEC lead-crystal cell battery : 700-800 cycles or 3100 cycles ?


The interested consumer has to ask directly the vendor/producer !


Sincerely
              OCWL


p.s.:
the DOD cycles are important to get a fair comparison between Lithium or lead solar/wind energy storage investments !

Good question.  According to their literature
it is designed to be a deep cycle battery
therefore it should be able to sustain many
more cycles of charge/discharge than the
typical gel battery or agm battery.

But, as always, it depends upon the charging
methodology to assure that the battery is
fully charged each time without excessive
gassing and consequent potential loss of
water from the electrolyte.  Many charging
devices are in fact somewhat abusive in
that they are not able to fully reverse all
sulfation and equalize the cells with each charge.

Mr mjlorton has made a youtube video where he performs a side by side comparison test between a real 22Ah Chinese crystal cell
acid/lead battery and a run-of-the-mill 18ah AGM battery. The results are surprisingly positive for the lead crystal cell
battery. And unfortunately, not so suprisingly - very negative for this small untyped AGM 18Ah acid/lead battery. The cc-battery
needs to be run against a higher quality acid/lead solar or traction battery if a low Ah capacity match could be found for it.
