In the battles, each coach groups the members of his team into pairs, so that they face each other in a ring and sing the same song, thus showing their best vocal and artistic skills. At the end of each performance, only one of them advances to the next round.  Beginning with the third season, at this stage each coach receives the opportunity for the «Stole», two in total, which allow them to save and incorporate into their teams contestants eliminated by other coaches during this round. In each season, each coach receives the help of invited mentors, who help him advise his participants to show off and perform well, providing their point of view to make the best decision for the team.
