I bought a PB-39 NiMIH replacement for my THD7 from WW Associates and  
to be quite honest neither their charger nor the battery impressed  
me. the charger was always problematic and the battery died almost as  
quickly as the original Kenwood. I have had my Maha PB-39Hs for  
several years with no sign of them dying yet.
