The Sealey ECS400 is a professional battery starter and charger engineered for modern vehicle requirements, combining fully electronic microprocessor control with advanced charging technology. Designed to handle the sophisticated battery systems found in today’s vehicles, this unit delivers versatile performance across both 12V and 24V electrical systems. This advanced charger supports the full spectrum of contemporary battery technologies, including EFB and AGM/GEL batteries used in stop/start systems, plus Lead Acid, Lead Calcium and Silver Calcium batteries common in electric and hybrid vehicles. The intelligent ten-phase charging system incorporates analysis, optimisation and trickle/maintenance modes to ensure optimal battery condition. ECS (Electronic Control Systems) technology provides stabilised charging current for improved efficiency and reduced charging times, whilst the LED read-out delivers instant visual feedback on battery condition, charge current, voltage and charging rate. Critical electronic systems receive comprehensive protection through integrated surge and spike circuitry, safeguarding vital components including ABS, airbag sensors, ignition and music systems during both charging and starting operations. The dedicated BSU (Battery Support Unit) mode maintains power supply during extended diagnostic procedures and software updates, preventing battery drain when workshop equipment is connected to the vehicle. With a battery range capacity of 4-550Ah and output starting peak of 400A (300A EN), this charger handles everything from compact cars to commercial vehicles.
