Batteries are brand new...the orig batteries since new 9/2008 were OK and I could get by with them for another 6 months or so but would read under 12 v when inverter on in about 2 hours....so I bit the bullet and replaced them...I don't dry camp often but lately I've had to go places with virtually no notice and didn't want them to fail me when I needed them..thank you all for your responses...I just didn't want to insult the person who gave me the gift. They don't know that much about RV's and wanted to help me...Too bad they didn't give me the tires I just purchased too...
