The new ATX12-HD is an extremely lightweight and high-power Lithium-Ion replacement (480 CCA!) for heavy lead/acid and AGM batteries. This is the HEAVY DUTY version of our standard duty AT12 offering more capacity/cranking power for those who need it; 480 CA, 16Ah! It offers the first FULL Battery Management System (BMS) found on a Powersport Battery and includes low-voltage cut-off, over discharge, over-charge, and thermal protections with real time lithium-ion cell balancing, and also offers the groundbreaking “RE-START” button – the first batteries with built-in jump starting! Never again worry about getting stranded with a dead battery! The RE-START Battery intelligently monitors its status, and just before going completely dead puts itself to sleep with just enough energy to get your vehicle started again. Simply press the RE-START button located on the battery, start your vehicle and ride away!
