Trojan's SmartCarbon Technology

[DMJ72]

Interesting webinar : https://www.youtube.com/watch?v=PnOcFdYshkw&list=UUUeq83LqdZkGxXo2tb6dwIg




Take aways :

* Proprietary addition of Carbon to Negative paste
* 15% Longer life @ partial state of charge applications only
* Lower resistance - 15% faster charge acceptance
* Only available in Premium and Industrial lines
* Trojan DOES NOT recommend mixing with older lines
* Older non-carbon lines are no longer being made
* No clear solution if you need to replace an existing model!

Pretty interesting stuff. I can say I see a distinct difference in these vs the old ones. I notice they are "Softer" so for the same say 500 watt load the voltage sags more while the load is there. it bounces right back when the load is removed.

They must be very confident in the technology to shift completely over.

Just saying.

* 15% Longer life @ partial state of charge applications only

The the charts for cycle-life vs DOD look the same as the old batteries, probably because those charts are not based on PSOC cycling.

Did they mention on the webinar how they tested the batteries to make their claim of 15% longer life?  As far as I know there is no widely accepted protocol for testing battery life under PSOC conditions.

If this is the case, then how can it be softer with more voltage sag and loading down as Ryan is
talking about ?

I have no real bone to pick with Trojan  ...

BUT,  their promotional material -  Brochures and Videos  seem to be so filled with Crap Marketing Phrases that it seems to me that it is mostly or all just pure BS,  Marketing Crap.

But have never run Trojan batteries,  unless West Marine batts were once Trojan.

Agree that Softer should mean lower Z.   Perhaps there are fewer,  thicker plates,  or something.   Guess that they are still using 1.277 (or 1.280)  SG electrolyte -- seems too high to me for typical RE use.

Just opinions,   Vic

US Battery thinks the vote is not in yet for Carbon in RE applications...

Yeah, they say the carbon doesn't help positive plate sulfation, BUT, US Battery IS advertising their OSP technique so of course they are going to poo-poo the competition.

I really have no idea if one is better than the other if they work good or not.

Me either. I will give you an opinion in 7-10 years 

I can say I am playing with a Carbon Foam battery made by FireFly here and so far I am impressed with the capacity vs size. I am really abusing the sucker so time should tell what it is all about as well. My normal morning voltage is in the low 11vdc range 

[Westbranch]

Maybe I am not correct but your heavy use(abuse) of the battery and a good recharge is what USB is recommending, no?
