Its 8-step intelligent charging curve handles everything from routine charges on cars and vans to recovery of deeply discharged cells and maintenance charging for showroom stock - all automatically, without supervision, and without removing the battery from the vehicle. Supporting batteries from 1.2 to 250Ah, it covers the full range of 12V commercial applications.\u003c\/p\u003e\n\u003cp\u003eThe integrated Supply mode transforms the Flash 12.12 into a stabilised 12V power source, keeping showroom vehicles live during demonstrations and preserving ECU and radio memory settings during battery replacement.
