The Reds, who appear to have run Manchester United close, but not close enough for the Premier League title this season, are expected to recruit several fresh faces in the summer in order to maintain their challenge for honours in 2009/10.
But the Spaniard has assured former Feyenoord striker Kuyt that there is no chance of him being shown the door at the end of the season.
The 28-year-old has been transformed from a deadly front-man in Holland to a workmanlike right winger during his three seasons at Anfield, but has earned lavish praise for his continual never-say-die attitude and tendency to pop up with crucial late goals.
"You could call him Mr Duracell, because of the way he plays, always running and always on the go," Benitez told the Daily Telegraph.
"But we knew when we signed him that he was that sort of player, because he has been doing it for years.
"He's done really well this year, creating things and scoring goals, but maybe that is because the team is doing better.
"You can use him in so many different ways so you can pretty much guarantee he will be in the starting line-up."
