The Varta Calcium Maintenance Free Battery is a direct-fit replacement for Isuzu D-Max and Isuzu MU-X and Mazda BT-50 models built from 2021 to 2023. Vibration-resistant plate construction is important for vehicles that see unsealed roads. The AGM construction handles the deep cycling created by stop-start systems and accessory loads. Calcium grid technology reduces water loss and self-discharge, which suits vehicles that sit for weeks at a time. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. Sold new with 24 Months warranty cover and full technical support.
