CEGASA has been manufacturing industrial and commercial batteries since 1934. Their air-alkaline batteries are well-suited for powering road traffic signalling devices due to their high and constant output voltage, long operating times of up to 7,000 hours, and reduced need for supervision and maintenance compared to saline batteries. CEGASA offers various air-alkaline battery models for applications such as road traffic signalling, railway signalling, navigation aids, telecommunications, and more.
