Can I get a replacement battery charger (model #3g14chul) for charging batteries(model #3g144bul) for drill/driver (model #3g144vul? My drill motor is still excellent and my two batteries will hold charges. Please replay to robertmlangley@bellsouth.net as it would be a shame to throw my unit away. Obviously this would weigh heavy on my decision to purchase GMC tools in the future. I would appreciate your help.
