The XB2 Smart Processor automatically diagnoses the battery condition on connection, then sequences through the 7-stage charge process covering recovery, bulk charge, absorption, and maintenance phases without any manual intervention and with no risk of overcharging. Batteries from 1.2Ah up to 120Ah are supported, covering everything from motorcycle batteries to full-size leisure and deep cycle batteries. The charger rescues deeply drained batteries down to 3 volts, extending the usable life of batteries that would otherwise be considered unrecoverable. Constant current charging, spark-proof operation, short circuit protection, and reverse polarity protection are all standard. The memory function retains vehicle settings during battery maintenance. Supplied with interchangeable battery clamps and eyelet terminals that plug directly into the charger lead without tools. IP65 rated for dust and water jet protection. Dimensions are 189 x 63 x 49mm. 2-year warranty.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003e\u003cstrong\u003eFeatures \u0026amp;
