Simply connect the red clamp to the positive terminal and the black to the negative, then plug it into a standard UK mains socket. The 7-stage microprocessor will automatically detect the battery voltage and begin the optimal charging cycle without any manual input required.\u003c\/div\u003e\u003cspan\u003eHow does the REPAIR mode work?\u003c\/span\u003e\u003cbr\u003e\u003cdiv\u003ePulse Repair mode is a special high-frequency recovery cycle designed for batteries that have become sulfated or have been left idle for long periods. It helps break down lead-sulphate crystals to restore battery capacity and improve cranking power, potentially saving you the cost of a new battery.\u003c\/div\u003e\u003cspan\u003eCan I use it on lithium batteries?\u003c\/span\u003e\u003cbr\u003e\u003cdiv\u003eYes, JoltNapo is fully compatible with modern LiFePO4 lithium batteries as well as all lead-acid types including AGM, GEL, SLA, and EFB.
