Had a long drive today so made a bunch of phone
calls to get more information cause this thread peaked my interest. I called Superior Battery
, US Battery
, Crown Battery, JCI, East Penn and Trojan. All US manufacturers.
Could not get anyone at Johnson Controls (JCI) or Deka/East Penn.
All this was prompted by the multiple references
here to plate thickness. Seems everyone hints or assumes that Trojan is the thickest but in all my years on these forums
I have yet to see anywhere the actual plate thickness of a T105 or T125.
So I call US Battery, Crown, East Penn, Johnson Controls (JCI) and Superior. Crown, US and Superior were all extremely helpful and supportive in my research
. These guys were all very into their product and excited to discuss their products and technology. Some even shared market share data by industry sector.
US Battery US2200 - 232 Ah, +Plate Thickness .110
Crown CR225 - 225 Ah, +Plate Thickness .105
Superior GC1200 - 220 Ah, +Plate .115
Trojan T105 - WE DON'T DISCLOSE THAT DATA
What, the "leader" in robust deep cycle batteries won't discuss plate thickness??? That's okay because both Crown and US Battery claim the plates are "around" .110, just as the others are, as they have both done battery autopsies on the Trojan's.
Apparently within the industry US Battery is very well respected. Both Superior and Crown eluded to this and their rather decent share of the golf car industry, which Trojan apparently has given up a lot of to US Batt. Trojan said, in reference to US Battery, "they basically copied our battery".
I was thoroughly impressed with Crown, US Battery and Superior. Trojan was surprisingly quite underwhelming. I called an 800 number then was asked to leave a message and they would call me back. I called back and was asked to be placed on hold, I did not use their 800 number, but was told "I am in California
and tech support is in Georgia
, there is no hold option".
The woman I spoke with, who finally called me back, was cordial but considerably less knowledgeable than the folks I spoke with at Crown, Superior and US Battery.
Trojan builds a good battery but I don't understand the "top secret" approach to plate thickness when you are supposedly the industry leader. The other three were all very excited to discuss technology, paste, separators, antimony content etc. etc. etc.... Trojan, not so much..
