Pro 2 batteries

[TBeaubian]

Two of my batteries are not charging in the station; there are no lights appearing on the charging station.  Does that mean that I need to purchase new ones?

I'd start by using the plug-in charger and cable on another device to see if that's working. Also verify that the charger you're using supports both 5 volts as well a 9 volts DC since the batteries will only charge with 9 volts.
