The Allrounder is built for starting and deep cycle requirements. The batteries are built extra strong with more power capabilities - high temperature tolerance, better vibration resistance and high cranking (CCA) & reserve capacity together with high ampere hour (AH) ratings. And with its Maintenance-Free design, the MRV battery reduces the risk of acid handling and spillage as well as contamination from dirt and dust. This battery is designed to meet the 4WD, MOTOR HOME/CAMPING, MARINE & LEISURE power requirements of the Australian market.
