Seems like there is acknowledgement that the start stop and manipulation of battery state of charge so that it can accept high amps on demand, is causing premature failure of the warrantied batteries that coe with new vehicles.
We know trojan and likely others are incorporating some carbon into the plate paste to make the battery more resistant to sulfation in partial state of charge cycling.
I see this stop start as a good thing, in terms of attempts to get batteries to outlast their 36 month warranty so that the auto manufacturer need not warranty them.
Starting batteries are now being intentionally cycled with modern vehicles, not just randomly depletion via stereo or lights, then hope 13.8v is good enough to make it last the warranty period.
Vehicles now seek to hold the battery around 12.8v or less driving down the road, and only allow 14+ when letting off the gas or braking.
This equates to intentional cycling and if they are attempting to address partial state of charge cycling so that the battery outlasts the warranty period offfered with the new car, well lets hope there is merit to the carbon plate paste additive.
Or perhpaps there is simply no room for any possible improvement to lead acid battery construction, and this is just more marketing for the masses and max profit.
