Batteries are commonly used to power portable traffic lights of the type used at roadworks. The type of battery is not specified in regulation or guidance. The technical specification covering portable signal equipment covers power outputs but does not specify battery type.

Local traffic authorities are responsible for approving roadworks, including use of portable traffic lights. It is for those deploying portable traffic lights to ensure that the equipment is safe and fit for purpose.
