Introduction
Alternator deletes have been shown to increase fuel economy as much as 10%. However, extra deep-cycle batteries (and/or another form of power) must be used as a replacement, and their cost may offset any economic savings of reduced fuel consumption.
That said, if your regular starting battery is in need of replacement anyway, it could be replaced with a good deep-cycle battery for not too much more money.
