FREE: rayovac Power Station with Batteries

The listing, rayovac Power Station with Batteries has ended.

I am not sure how old they are. They do take a charge. I have tested it and they charge fine. I am not sure how to tell how old they are. I bought it and thought I was going to use it because it was near Christmas but I never needed it.
The c batteries are 4230; I know the rayovac charger is a renewal ps2 for c, d, aa, aaa, up to 8. There is a PS1 that charges up to 4 AA, AAA batteries. Does this information help?
I have a power station renewal item that charges batteries of different sizes. It is from rayovac and it is model ps2 and ps1. They can hold up to 4 AAA or 4 double. I have 3 of those chargers. I also have 15 c batteries, 1 d, and 5 AAA. I am posting a link for more details because I am not sure on all of it. I know is a lot and its heavy.
