The victory tasted even sweeter as the women had returned empty handed from the Glasgow edition four years ago. It was only the second table tennis team gold for India at the Games with the men achieving the feat in the 2006 Melbourne edition.
Earlier today, India had blanked England 3-0 to reach the women's team final for the second time.
While Batra was the architect of India's historic win, the experienced pairing of Madhurika Patkar and Mouma Das played the supporting role to perfection by winning the crucial doubles tie 3-1 (11-7 11-6 8-11 11-7) against Zhou and Mengyu Yu for a 2-1 lead in the final.
After Batra shocked Feng 3-2 (11-8 8-11 7-11 11-9 11-7) in the opening singles, Mengyu had equalized for Singapore with a straight game win over Patkar.
Batra then proved to be too good for Yihan, who failed to read her deceptive strokes. The Singaporean put a back hand long as the Indian completed a 3-0 (11-7 11-4 11-7), leading to wild celebrations.
