Ray,
As a battery-only wrench I stock and sell many brands. Not sure where you saw
Deka = Trojan but from years of first hand experience, Deka’s are not anywhere
near Trojan in life cycles. Also, FWIW dealers, if you sell Deka, check the
micro date code on the side of the case. I have received pallet loads of 8D and
4D AGM’s that were over 1 year old when delivered.
Just for the fun of it, my opinion is that Johnson Control (JC) is the worst
performer. Just have a look at your JC Sam's Club $68 GC2. A 1-3 year battery.
About the same for the JC Interstate green top GC2.

Geez, I got that file on a model specific google search. It has a picture of a
4000 series flooded cell to the side, no other labeling, and it matched my
cross check in the AEE catalog (1000 cycles at 50% DOD). I can't seem to get to
that page within the website.....
The chart you sent is labeled series 4000, and is labeled 1280 cycles @50% DOD
(very definitive, very different). Did both myself and AEE indeed use the wrong
data?(I see the AGM tag) I have another s460 spec sheet claiming 1300 cycle 10
year life with no DOD mentioned.....
Its like shopping for tires or a mattress, you never know what to believe,
other than real experience sometimes. I had a horrible time for instance
finding cycle data for Deka, and I'm still not sure if what they sent is right
(that Deka = Trojan) I had conflicting charts and numbers from Trojan too.....
Be nice to have an independent test facility and publish some trust worthy
comparison data on a level playing field. I based my Rolls info on almost a
decade of literature collected from them, not just that one chart.
Awaiting clarification from Rolls, sorry if I used the wrong data
