After Market chargers

Hello. I have an old KENWOOD TH-78A. I can’t find either the wall charger or the base charger. I do have the AA battery cartridge so I can use the radio, but have been unsuccessful in finding either the original or any aftermarket chargers for the PB-13 ncad 7.2v, 7mHa battery pack. Do any of you have any suggestions? The radio is in perfect condition, but it eats through those AA batteries pretty fast. Thanks

appears to list that battery as the same as the others listed - does yours look like that?
