Wahl Professional 5 Star Cordless Retro T-Cut Trimmer Parts or repair

item hasn't been used in a year or two, it is not taking a charge, consider this for parts or repair.  I did meter the charger stand it is working and output is 1.6v DC, so that appears ok.
you get the trimmer and charger in this purchase, please ask prior to bidding,  I will ship the most economical method and carrier i can get at my choice, normally just usps but I do compare prices.
