Does anyone know what would have been the original charging solution for Walkmans that used AIWA PB-4 rechargeable batteries (for instance in an HS PX410)? I was unable to locate the proper user manual or identify a charger type provided by AIWA) Thanks!
Don't know what kind of battery that is without searching the internet so I'll just say this. I charge my gum stick batteries this way in a Nightcore Multi-Voltage multi battery charger
Well then I suggest you get your handy dandy jumper cables and make a battery compartment charging thing and make it work. That's what I've been doing is making things work. I just found this spring that I can use on my little flywheel here that needs a spring here. I'll put that close to that and take a picture
