OPTIMA YellowTop DS46B24R Dual Purpose AGM Battery - High Performance

In this review the OPTIMA YellowTop DS46B24R is evaluated as a dual-purpose, maintenance-free battery for vehicles with high electrical demands. The bottom line: this battery is best for drivers who need dependable starting power plus reliable deep-cycle reserve for accessories or winches, because its SpiralCell AGM construction and 450 CCA deliver consistent starts while offering superior rechargeability and vibration resistance compared with standard flooded batteries.

Key Features

• 450 Cold Cranking Amps: Provides strong starting power in cold or adverse weather to help engines turn over reliably.
• SpiralCell Technology: The spiral-wound cells use 99.99% pure lead for more consistent power output and longer life versus flat-plate designs.
• Dual Purpose AGM: Designed for both starting and deep-cycle use, so it can handle accessory loads and repeated recharge cycles.
• Reserve Capacity 66 min: Offers extended run time for electrical accessories or emergency use without immediately draining starting ability.
• Maintenance Free: Sealed AGM construction eliminates topping up and simplifies installation and ownership.
• Faster Charging: Improved recharge characteristics help the battery recover more quickly after heavy use.

Who It's For

The OPTIMA YellowTop suits drivers of trucks, SUVs, commercial vehicles and accessory-heavy cars who need both solid cranking and reliable deep-cycle performance for audio systems, winches, or aftermarket electronics. It also fits select Prius models where a compact, high-performance AGM is required and fits in tighter battery compartments.

Customers who primarily want the absolute lowest price and will accept more frequent replacements from standard flooded batteries should look elsewhere; likewise, vehicles with minimal electrical load do not need the YellowTop's elevated cycling capability and reserve capacity.
