Built with OPTIMA’s SpiralCell Technology and 40 years of engineering experience, the YELLOWTOP DS46B24R combines reliable starting current with sustained reserve capacity for modern vehicles and demanding applications. This sealed AGM battery is maintenance-free, vibration-resistant, and designed to recharge quickly while tolerating repeated deep-discharge cycles. It’s a compact, 26-pound battery suited to cars, trucks, commercial machines, and specialty uses where both starting and accessory power are required.

How does this battery balance starting power and deep-cycle capability?

The YELLOWTOP uses OPTIMA’s SpiralCell design and pure lead plates, engineered to deliver strong cold cranking amps for reliable starts while providing sustained output for electrical accessories. Its AGM construction lets it accept charge faster and tolerate deeper discharges than conventional flooded batteries.

• 450 Cold Cranking Amps for consistent starts in varied conditions
• 38 AH (C20) capacity to support accessories and lights
• Sealed AGM chemistry for repeated rechargeability without maintenance
• 66 minutes reserve capacity to run loads when alternator output is reduced

What are the durability and maintenance advantages of the YELLOWTOP?

Designed for tough environments, the DS46B24R resists vibration and physical stress far better than standard flooded batteries. Being sealed and maintenance-free eliminates the need for periodic water top-ups and reduces corrosion risks at terminals.

• Up to 15x more vibration resistance than flooded alternatives
• Sealed AGM design prevents leaks and reduces maintenance
• Corrosion-resistant posts and robust case for longer in-service life

Will this battery fit my vehicle and recharge quickly?

The compact dimensions and SAE post layout make this battery suitable for many engines and replacement applications that accept size DS46B24R. AGM construction means faster recharge rates under compatible charging systems compared with traditional wet-cell batteries.

• Size: 9 5/16" x 5 1/16" x 8 15/16" — fits many common trays and mounts
• Weight: 26 pounds for easier handling during installation
• Faster recharge characteristics when used with smart or high-output alternators

What real-world uses is this battery best suited for?

The YELLOWTOP DS46B24R is engineered for vehicles and equipment that need reliable starting plus deep-cycle capability for accessories. It’s commonly selected for trucks with winches, audio systems, commercial vans, agricultural machines, forklifts, and other heavy-duty or aftermarket-equipped platforms.

• Ideal for accessory-heavy cars and trucks with high electrical demand
• Works well in commercial vehicles and off-road equipment with repeated loads
• Suitable for specialty uses like forklifts, tractors, and utility machines

Who is this for: The OPTIMA YELLOWTOP DS46B24R is aimed at drivers and operators who require a dependable, maintenance-free battery that can both start engines reliably and supply sustained power to accessories. Enthusiasts, commercial users, and owners of equipment that undergo frequent deep-discharge cycles will value its SpiralCell performance, vibration resistance, and sealed AGM convenience.
