DeWalt DXGNR7000 generator - very low hours

I’m a selling my DeWalt 7000 watt generator. Has been used very seldom, under 15 hours of use. This comes complete, the unit has electric start but I never used it much so the battery has gone flat. Does have A/C charger to charge up battery. Feel free to bring along your equipment to try it out. Here is the link to the specifics of this generator. {url removed}
