Ben Sheridan, AA Patrol of the year said modern cars should be able to last at least two weeks without needing to be stated.
However, Mr Sheridan said those with older vehicles or those with concerns over the quality of their battery should start it once a week to be safe.
He said: “The first working day back in January is typically one of the busiest of the year for break downs, with flat batteries the main culprit.
“Over the Christmas break many cars get left unused – this causes the output of the battery to drop which, especially for old batteries, can mean they don’t have the power to turn the engine over.
