Hello again. Just got my new Volt yesterday. A couple of questions. What does the 12 volt battery run. Is it just for starting or any lights, radio, or ???? Also my elect co rate is about 11 cents klw so how do I figure how much it cost per night or month? I know GM said about $1.50 per night. x 30 that adds up to $45 per month. divided by $3.85 per gal of prem gas. that would be like 11.6 gals. Does that sound right? That still would bring me down to 100 mpg which is still better than the 17mpg I was getting. Anybody tried offpeak elect.? I'm sure these questions are in the forum someplace, but not sure how to find them. Just went over to Home Depot 14 miles round trip and only used 8 elect miles. Did some coasting when there was no traffic and kept it at below 55 so I think I did good.
