Install Duracell Professional and the truck will reach its destination! In order to perform daily in trucks, buses, agricultural and construction machinery, batteries have to be made out of something special! The power source that is Duracell Professional – available as HD/Heavy Duty and SHD/Super Heavy Duty – will reliably start every engine in all conditions, together with providing sufficient energy to the onboard vehicle systems. The complete construction is based on absolute robustness. The SHD versions offer the highest safety features such as central venting and safety plugs. In addition, the 145/180/225Ah batteries feature the centrally vented 4-chamber flat lid, to prevent electrolyte leakage, which incorporates an integral flame arrester for additional security.
