High-demand electrical systems place sustained stress on conventional batteries, causing premature failure through deep discharge cycles and prolonged drain from auxiliary loads. The Optima YellowTop 8051-187 is a dual-purpose AGM battery engineered to deliver reliable engine starting and sustained cyclic performance within a single unit, making it a dependable solution for vehicles with aftermarket electronics, commercial plant, heavy equipment, and specialist applications including emergency vehicles.
Optima's proprietary SPIRALCELL technology constructs each cell from two pure lead plates wound into a tight spiral configuration. This design provides a larger and more consistent surface area than flat-plate AGM alternatives, resulting in superior vibration resistance, faster recharge acceptance, and a longer service life across repeated deep discharge and recharge cycles.
The YTS5.5 operates at 12V with a 75Ah (C20) capacity and 975 CCA, providing substantial cold-start performance alongside deep-cycle capability. Physical dimensions are 325mm × 165mm – 238mm (L × W × H) with a weight of 27.9kg. The battery features Terminal Type 1 fitment with reverse polarity (polarity code 2) and B00 hold-down configuration. No direct cross-references are listed; fitment must be verified against the vehicle manufacturer's specification. The technology supports start-stop systems – confirm compatibility via the product label." This product is available as a single unit. No additional variants are offered within this listing. The Optima YTS5.5 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.
