OPTIMA YELLOWTOP DH6 AGM dual-purpose car battery — 800 CCA, 140 min reserve, 72 Ah

OPTIMA YELLOWTOP DH6 is a sealed AGM dual-purpose battery delivering high cranking power plus deep-cycle performance for accessory-heavy vehicles.

Designed for drivers who need reliable starting power and dependable reserve capacity, the OPTIMA YELLOWTOP DH6 combines absorbed glass mat (AGM) construction with PUREFLOW radial plate technology. That engineering yields a maintenance-free, spillproof battery that recharges quickly, resists extreme vibration and lasts significantly longer than conventional flooded batteries. It’s ideal where both strong ignition performance and repeated deep discharges are required.

How much starting power and reserve capacity does the YELLOWTOP DH6 provide?

The DH6 delivers 800 Cold Cranking Amps (CCA) and a reserve capacity of 140 minutes, balancing strong starts with extended support for electronics. That reserve capacity helps maintain consistent electrical output during prolonged accessory use or when alternator output is limited.

• 800 CCA for reliable cold starts
• 140 minutes reserve capacity for sustained power
• 72 AH C20 capacity supporting accessory loads
• DIN A1 terminal configuration for secure connections

What technologies make this battery more durable than a standard flooded battery?

OPTIMA’s PUREFLOW technology uses 99.99% pure lead in highly compressed radial grid plates, improving resistance to vibration and corrosion. The sealed AGM design prevents spills and allows mounting in varied orientations while protecting internal components from damage.

• Highly compressed radial plate construction resists vibration
• 99.99% pure lead reduces corrosion and extends life
• AGM sealing prevents electrolyte leakage and allows flexible mounting
• Up to 15x greater vibration resistance versus standard flooded batteries

How does the YELLOWTOP DH6 handle recharging and maintenance?

The DH6 recharges faster than many conventional batteries thanks to its AGM chemistry and optimized plate design. It is maintenance-free—no watering or regular terminal servicing—making it convenient for high-use and hard-to-access installations.

• Faster recharge rates compared with flooded batteries
• Maintenance-free operation—no electrolyte topping required
• Sealed construction for clean, safe installation
• Durable terminals and case for long-term reliability

What are the physical size, weight and fitment details I should know?

The DH6 is a compact, heavy-duty unit engineered to fit many performance and commercial applications. Verify dimensions and terminal type against your vehicle specifications before purchase to ensure proper fit and secure mounting.

• Dimensions: 10.94" L x 6.89" W x 7.5" H
• Weight: 54 pounds for robust, vibration-resistant construction
• Capacity: 72 AH (C20) and DIN Type A1 terminals
• Sealed case allows flexible orientation and safer installation

Who is this for: The OPTIMA YELLOWTOP DH6 is aimed at drivers and professionals who demand both strong starting power and repeated deep-cycle capability—think trucks with winches, vehicles with high-demand audio or electronics, commercial equipment, and off-road or industrial machines that face heavy vibration and frequent discharge cycles. Choose this battery if you need a maintenance-free, spillproof power source that recharges quickly and outlasts standard flooded alternatives.
