Going alternator-less may be an effective efficiency mod, but it's definitely not a money saving mod unless you have a source of free or cheap batteries.
I have to disagree. A good deep cycle battery can last over 5 years if you don't go below 50% discharged often.
On a metro it would take longer to pay for itself but on mine, (25mpg average) It paid for itself within a year. I picked up an excellent automatic charger for $36 and my batteries at Costco for $50 each x 2

Excellent article though, as always.

I wish I knew how to set up exel spreadsheets. It would be helpful to be able to figure out the possible savings vs costs per vehicle based on current draw, battery costs and gas savings.
