Dewalt 18V XR 4Ah Battery DCB182-XJ

Will not charge on charger properly. This product was made in China. Package states that the product could be made in China, South Korea or Malaysia but you will not know where it was made until you open the packaging, which you can not do until you have purchased the product. Previous iterations I have were made in Korea which still work well on the charger. I will have to return the product. I have rated this product with three stars as previously products I have purchased I have not had a problem with. This one may have escaped quality control without being checked properly. We all have a bad day.
