Honda Civiv Hybrid long term storage problems

My owner’s manual states that if I don,t drive my 2007 Civic Hybrid at least once a month, serious damage may occur to the 158 volt Nickel-metal-hydride batteries. I plan on being out of the country for three months and there isn’t anyone that can drive the car. I can’t be the only person faced with this situation What is my best course of action?

Thanks,

Earl Jones
