General condition is good, the aerial is in good condition. The battery terminals have not corroded on either the phone or battery but as i suggest with all old devices that use NiCad batteries you should probably store them separately so that if it leaks it doesn't damage the phone.
Obviously the battery will not hold a meaningful charge, I have tried charging it overnight and you get about 5 minutes of life out of it if you're lucky. As you can see it was happy to stay alive with no charger for the photos.
Listed for parts or not working because there's no way of actually testing calls etc, you can see that it does power on when connected to the correct Nokia charger.
These old Nokias are funny about their chargers and you will need the correct ACH-12X charger for it to do anything.
If you have any questions or are looking for a different vintage mobile phone please get in touch, I have over 300 phones which I am slowly listing. Its a mammoth job which I am trying to fit in between working full time and looking after a 2 year old!
I am happy to create a specific listing for you if I have something that you want so that you can see it.
