Product Number: YTS2.1
Dual-purpose battery applications demand a power source capable of both reliable engine starting and sustained cyclic discharge – a combination that conventional flooded batteries frequently fail to deliver. The Optima Yellow Top 8018-356 is a 6V AGM battery engineered specifically for vehicles and equipment where high-draw accessories operate alongside the core starting function, including commercial vehicles, heavy plant, emergency vehicles, and specialist builds with elevated electrical demand.
Optima's Spiral Cell AGM construction eliminates free electrolyte by suspending the acid within fibreglass matting wound into discrete cylindrical cells. This design delivers a highly stable internal structure, low self-discharge, strong vibration resistance, and the capacity to withstand repeated deep-cycle use without the sulphation damage common to flooded alternatives.
The YTS2.1 is rated at 6 volts with a 55Ah capacity (C20) and 765 Cold Cranking Amps. Physical dimensions are 254mm × 90mm – 203mm (L × W × H) with a weight of 9.5kg. The battery features a Terminal 1 post configuration with B01 hold-down, and a 6V0 polarity arrangement. No direct cross-references are listed; buyers should verify fitment against their application's terminal layout and tray dimensions. Start-stop compatibility is technology-supported – confirm against the product label before fitting." No additional variants are available for this product reference. The YTS2.1 is supplied with a 2-year manufacturer warranty covering defects in materials and workmanship under normal operating conditions. "Standard delivery: 1–3 working days within UK mainland. 30-day returns.
