Only charging one battery?

[720_]

I have a remote control car which uses a battery pack of two 3.7v capacitors and a 4pin plug with 4 wires coming from the plug when I charge the batteries using a usb charger it only charges one battery, I tested it using my mustimeter that's how I know.

 

Is this normal or is something broken?

Are you sure they are capacitors and not batteries.  Those two things look a lot alike but are totally different in the way they work.  Or, does it have two capacitors AND two batteries.  Not to sure what you have from the way that you describe your setup.
