The positive of the cap goes directly to positive of the input battery positive.

The negative of the cap goes through the diode of the input battery negative.

With the diode in that direction, current can move from cap to battery but the battery current cannot move to the cap. That is how the recovery can be sent to the front to be used, but we prevent the input battery from seeing the cap.
