Kulat, who is from Nagpur, was sentenced to seven years and eight months in prison by the Manchester Crown Court after pleading guilty to rape, false imprisonment and causing actual bodily harm, the report said.
He faces being deported back to India following his release, the metro.co.uk reported. Police said the woman had been on her way to a friend's house when she realised her phone's battery was flat on March 19. She walked into the shop where Kulat was working in Withington to ask if she could charge it briefly inside the shop.
"After she plugged her phone in, Kulat locked up the shop, became aggressive and refused to allow her to leave," a spokesperson for Greater Manchester Police said.
"He hit the woman in the face and the body with a wooden pole repeatedly, causing serious bruising and swelling. The attack was so vicious that the pole actually broke into several pieces."
Speaking after sentencing, Detective Constable Laura Hughes, from the force's sexual offences unit, called the attack "despicable".
"Kulat subjected her to a violent and terrifying ordeal, which will haunt her for the rest of her life and nothing will repair the psychological damage he has inflicted," she said.
"I want to commend her bravery in coming forward to report this shocking attack and helping to secure this conviction," Hughes said.
