Aiwa PB batteries compatibility

Does anyone know what Aiwa PB batteries fits/are compatibile with which Aiwa models?
For now I would like to know about PX101 and PX303, but I think there could be a sticky thread because there are now litiumIon replacement batteries on Aliexpress.
Thanks

 

wish i could help the px101 didn't even know it ran on rechargeable batts and i have had loads of them, dementia comes to mind lol the 303 is that the one with dolby c pic please....if so
i have one but it fell behind my chest of draws which i have all my amps on so it can stay there

but wouldn't a panasonic one fit, I'm not sure of that though

 

damn the 303 is the one i have Raul..... it would take me hours just to move my amps and set them back up again but i am tempted but it may kill me lol

 

If it's hard to get I would avoid it

 

done i need a couple of walkman screws as one is missing off the door hinge. walkman still works and sounds superb ladit's you're fault god bless atb Reno

 

For now if I think correctly PX101 use PB1 and PB3, PX303 probably PB4?

 

Please check the Dolby C overview in my signature too. I included the batteries of the units and am happy to make changes when required.

 

Thanks, I didn't know you added the battery in chart

Strange, PX20 which is supposedly same package but different head and electronics to PX10 is listed as using PB-2.
I'm not sure, but aren't PB1, 2 and 3 compatibile?
