High-demand electrical systems – from uprated audio installations to auxiliary lighting rigs and emergency vehicle equipment – place conventional flooded batteries under sustained discharge stress that leads to premature failure. The Optima YellowTop 8073-176 is a dual-purpose AGM battery engineered to deliver both reliable engine-starting performance and deep-cycle capability within a single unit, making it the correct specification choice where repeated discharge and recharge cycles are unavoidable.
Optima's proprietary SPIRALCELL technology binds two pure lead plates into a tightly wound cylindrical cell, eliminating the plate separation and electrolyte stratification that degrade flat-plate AGM designs over time. The result is a spill-proof, vibration-resistant construction with a consistently low internal resistance, supporting strong cranking output and sustained power delivery across the discharge curve.
The YTR2.7 operates at 12 volts with a rated capacity of 38Ah (C20) and a cold cranking amp rating of 460A (EN). Physical dimensions are 237mm (L) × 129mm (W) × 227mm (H including terminal). The battery uses a standard SAE post terminal arrangement (Terminal Type 1, Polarity Code 0, standard positive left) with a B00 hold-down configuration. Weight is 12.5 kg. No direct cross-references are listed; verify fitment against vehicle manufacturer specifications. The technology is compatible with start-stop systems – confirm suitability via the product label before fitment." No variants are currently available for this SKU. This battery is supplied with a 2-year manufacturer warranty against defects in materials and workmanship. "Standard delivery: 1–3 working days within UK mainland. 30-day returns.
The OPTIMA YELLOWTOP high-performance AGM Battery is a dual-purpose battery for starter and cyclic applications. It is ideal for vehicles with high-demand electronics, commercial vehicles, heavy equipment and special applications like emergency vehicles. You can rely on this battery to provide ultimate starting and deep-cycle power.

A. The Optima YTR2.7 (8073-176) is a 12-volt battery with a rated capacity of 38Ah measured at the C20 rate and a cold cranking amp (CCA) rating of 460A to the EN standard.
A. The YellowTop designation indicates a battery designed for both engine starting and cyclic deep-discharge applications. Unlike a conventional starter battery, it is constructed to withstand repeated discharge and recharge cycles without significant capacity loss, making it suitable for vehicles with sustained auxiliary electrical loads.
A. SPIRALCELL technology is Optima's proprietary construction method in which two pure lead plates are wound into a tight cylindrical cell. This eliminates plate movement and electrolyte stratification, resulting in low internal resistance, consistent power output, resistance to vibration damage, and a longer service life compared with conventional flat-plate AGM designs.
A. The battery measures 237mm in length, 129mm in width, and 227mm in height including the terminal. It weighs 12.5 kg.
A. The YTR2.7 uses a standard SAE post terminal (Terminal Type 1) with Polarity Code 0, indicating standard positive-left orientation. The hold-down classification is B00. Always verify terminal position and polarity against your vehicle's battery tray layout before fitment.
A. The AGM technology used in this battery is generally compatible with start-stop systems. However, Optima advises that suitability should be confirmed by checking the product label, as start-stop compatibility can vary by vehicle application and specification.
A. The YellowTop 8073-176 is suited to vehicles with high-demand electrical systems, including those with aftermarket audio equipment, uprated lighting, auxiliary power inverters, emergency vehicles, commercial vehicles, and heavy equipment where the battery may experience regular deep discharge.
A. AGM batteries, including this Optima YellowTop, should be charged using a charger that is compatible with AGM or VRLA battery chemistry. Standard flooded-battery chargers set to high voltage profiles may reduce battery life. Consult your charger manufacturer's guidance to confirm AGM compatibility before use.
A. The battery is supplied with a 2-year manufacturer warranty covering defects in materials and workmanship under normal use conditions. Retain proof of purchase for any warranty claim.
A. Standard delivery within UK mainland takes 1–3 working days. A 30-day returns policy applies. For full terms and conditions, refer to the PartsForMachines returns policy at the time of purchase.
