Power on display at the Rugby World Cup, which kicked off last month and is set to run until the end of October, is being measured by Duracell.
#powerCheck measures power and endurance to help fans to understand more about teams, players and key moments during the tournament.
As an official tournament provider, Duracell is also providing a range of its batteries to support the tournament.
To mark the sponsorship, the brand has created a film of defining moments in rugby. The film features Welsh international rugby player Sam Warburton.
It will run on YouTube and Facebook until November.
