Product Number: YTU4.2
Variations
High-demand vehicle electronics, auxiliary loads and frequent deep-cycle use place considerable strain on conventional batteries, often resulting in premature failure. The Optima Yellow Top YTU4.2 (8014-254) is a 12V 55Ah dual-purpose AGM battery engineered to handle both engine starting and cyclic discharge duties within a single unit, making it a direct solution for applications where a standard starter battery is insufficient.
Optima's Spiral Cell AGM construction uses tightly wound lead plates separated by absorbed glass mat, eliminating free electrolyte and delivering a consistent power cell. This design provides vibration resistance, a low self-discharge rate and the ability to withstand repeated deep-discharge and recharge cycles without significant capacity loss – characteristics that set it apart from conventional flooded lead-acid technology.
The YTU4.2 measures 254mm × 175mm – 200mm (L × W × H) and weighs 20.6 kg. It produces 765 CCA (EN) and is rated at 55Ah (C20). The terminal configuration is top-positive with an additional side terminal (Type 1 + Side), with standard polarity 1 (positive right). Hold-down type is B00. Start-stop technology support is indicated – verify compatibility against the product label before fitment. No direct cross-reference part numbers apply; refer to vehicle manufacturer specifications to confirm suitability." This product is supplied as a single battery unit. No variant configurations are available for this SKU. The Optima Yellow Top YTU4.2 is covered by a 2-year manufacturer warranty against defects in materials and workmanship. "Standard delivery: 1–3 working days within UK mainland. 30-day returns.
