Hey Spectra System Polaroid Camera owners! Help?!? - how do i charge the battery on my spectra system polaroid camera

I inherited a perfect instant camera Polaroid Spectra! So excited.
But here's the bad news

Red and green.
A red arrow saying "loading"
Green is the that, "says Ready

But I have a charger is not in the case?
This camera is the battery?
or do I need a charger that I can not?
If so, where can I get this magazine?
