Sounds good, although not great, but I think not easy to sell for a high amount due of the limited people that is in this subject and would consider to use this name, so I see good idea to offer this domain contactiong people in the battery business and ask them if they are interested, maybe you could tell them they make an offer or you could test a higher amount at first to see what happen
You call their support number and ask for a refund on the domain and they instruct you to delete the name and they will refund your money within a week.
I think they give you a couple of days to a week to grace delete the domain. Too late now though. Best bet would be to auction it off on namepros or email battery companies, although I don't feel this one will sell to an enduser.
