Novak smart tray as charger tray

[OneKiwi]

I have a novak smart tray that I was going to throw away but thought I could use it as a charging tray.
Can it be done for C A AA AAA?
I was thinking something like this:



Can I then charge several batteries at a time?
Just slot them in and off I go?

And I have several C batteries that have no power at all in them, can I give them life... (lightning strikes and a sinister laugh muuhahaha) I was thinking about using them in a glow starter for the nitro car
