OPTIMA YellowTop YT R 2.7 J AGM lead-acid battery 12V 38Ah

The OPTIMA YellowTop YT R 2.7 J is a revolutionary high-performance AGM battery that combines the maximum starting power of a starter battery with the cycle stability of a supply battery thanks to the patented SPIRALCELL TECHNOLOGY®. With a nominal voltage of 12 V, a capacity of 38 Ah and a high cold-start current, it is the ultimate solution for modern vehicles with extensive electrical equipment, powerful hi-fi systems or demanding off-road accessories. Its extreme vibration resistance and absolutely maintenance-free, leak-proof design make it the first choice for the most demanding applications.

Highlights at a glance

• Dual-purpose functionality: Maximum starting power and excellent cycle stability in one battery.
• SPIRALCELL TECHNOLOGY®: Unique spiral cell design for extreme vibration resistance and a longer service life.
• High cycle stability: Ideal for vehicles with many electrical consumers and for repeated deep discharges.
• Absolutely maintenance-free and leak-proof: The sealed AGM design allows installation in almost any position.
• Fast recharge: Absorbs charge significantly faster than conventional batteries.

Maximum performance for demanding vehicles

The OPTIMA YellowTop YT R 2.7 J was developed specifically for the extreme requirements of modern vehicles, which go far beyond mere starting. It is the ideal choice for vehicles with sophisticated sound systems, auxiliary headlights, winches, hydraulic systems and other energy-intensive consumers. The YellowTop also proves its superior performance and longevity in vehicles with seasonal use or many short journeys that place a heavy load on conventional batteries.

Superior SPIRALCELL TECHNOLOGY®

At the heart of every OPTIMA battery is the unique SPIRALCELL TECHNOLOGY®. Instead of flat lead plates, high-purity lead spirals are used, which are wrapped in a glass fibre fleece (AGM). This compact and extremely stable design minimises plate spacing and internal resistance, resulting in outstanding starting power, faster charging and unsurpassed vibration resistance. This technology makes the YellowTop the perfect hybrid solution for starting and supplying.

Built for the most demanding conditions

The OPTIMA YellowTop is designed for tough applications. Its sealed construction not only prevents acid leakage but also evaporation, making it completely maintenance-free. The robust construction made of impact-resistant polypropylene and the up to 15 times higher vibration resistance compared to conventional batteries ensure that vibrations and shocks cannot harm the battery in demanding driving conditions.

FAQs about the OPTIMA YellowTop battery

What is the main advantage of SPIRALCELL TECHNOLOGY®?

The spiral cell technology ensures an extremely robust and vibration-resistant internal structure, very low internal resistance for high starting currents and excellent cycle stability. It combines the advantages of a starter battery with those of a deep-cycle battery in a single product.

What is the difference between OPTIMA YellowTop and RedTop?

YellowTop: A dual-purpose battery (starting and supply). It is ideal for vehicles with high energy requirements due to additional consumers (e.g. winches, large hi-fi systems) as it can withstand deep discharges. RedTop: A pure high-performance starter battery for maximum starting power. It is the right choice if the starting process is the main load and there are no deep discharge cycles.

What does the suffix "J" in the model name mean?

The letter "J" in the model designation YT R 2.7 J stands for "JIS" (Japanese Industrial Standard). This means that the battery has the narrower, conical battery terminals that are typically used in Japanese and other Asian vehicle brands.

Which charger do I need for this AGM battery?

For AGM batteries, especially for OPTIMA batteries, a modern, microprocessor-controlled charger is recommended, which has a special charging cycle line for AGM batteries. This ensures a complete and gentle charge and maximises the service life.

How should this lead-acid battery be disposed of?

Lead-acid batteries contain environmentally harmful substances and must not be disposed of with household waste. You can return your old battery to any retailer that sells new batteries or to municipal recycling centres free of charge to ensure that it is recycled properly.
