Model number of Vacuum is HNV2158 (7.2v 1.5Ah) and charger model is 90629041. The charger doesn't have to be the same model I just listed, but it should be a Black+Decker and must be a base model that the vacuum can sit on when charging. If you look at the pic of the metal charging contacts on the bottom of the vacuum, they are 1-1/4" apart measured from inside of one contact to inside of other contact. Charger needs to be in good working and cosmetic condition. Call me with questions or email me. Thanks, George. Will pay reasonable price.
