depends on how the battery is used, in a car NO...it has a constant manner of replenishing via the alternator.

Any system that has a method of replenishing would not gain any real advantage. There's a lot of digital periphery in vehicles, power is not a problem in running them no matter how inefficient they might be. The digital draw is almost invisible from a 700 amp battery.

Take that 700 amp battery not having a localized replenishment, utilize it for digital processes, and e.Digital can make it last longer(months...lol), the processes have nothing to do with the battery, other than using up the amps.

All digital processes drain power.  e.Digitals,  digital process, consumes less power than the norm when driving large video/audio files.

They're powering digital signals and nothing more....micro milli amp processes.....and does not compare to electric motors drawing mountains of amps.

1 milliAMP is 1000th of 1 amp and their utilizing micro fractions of a 1 milliAMP....lol...we're just not driving electric motors.
