OPTIMA YELLOWTOP DS46B24R 12V AGM Car Battery — 450 CCA, 38Ah Dual-Purpose Sealed

OPTIMA® YELLOWTOP DS46B24R is a sealed, dual-purpose 12V AGM battery that delivers strong starting power and reliable deep-cycle performance for accessory-heavy vehicles and equipment.

This OPTIMA YELLOWTOP is engineered to meet the demands of modern vehicles and work machines that combine frequent starts with extended electrical loads. Built with SpiralCell™ technology and a rugged sealed design, it provides consistent cranking, enhanced vibration resistance, and faster recharge compared with conventional flooded batteries. The DS46B24R format fits many mid-size applications and offers a compact footprint with impressive capacity and reserve time.

How much starting power and capacity does this battery provide?

The DS46B24R supplies 450 cold cranking amps for dependable starts and a C20 rated capacity of 38 amp-hours for sustained accessory use. Its sealed AGM construction preserves performance when temperatures drop and helps maintain voltage under load.

• 450 CCA for reliable cold starts in a variety of climates
• 38 Ah (C20) for running electronics and accessories between charges
• 66 minutes reserve capacity to support continuous electrical draw
• SAE post terminals for common vehicle connections

What makes SpiralCell™ and AGM construction better for heavy electrical systems?

SpiralCell™ uses tightly-wound pure lead plates that increase surface area and lower internal resistance, delivering stronger bursts of power and improved recharge acceptance. The Absorbed Glass Mat (AGM) sealed design holds electrolyte in place for spill-free mounting and reduced self-discharge.

• 99.99% pure lead for higher conductivity and power density
• Sealed AGM reduces maintenance and allows flexible installation angles
• Faster recharge times compared with flooded batteries
• Up to three times the life expectancy versus standard flooded designs

How durable is this battery for off-road, commercial, or heavy-duty use?

OPTIMA YELLOWTOP batteries are engineered for rugged environments, offering superior vibration resistance and long service life. That durability helps protect against premature failure in trucks with winches, construction equipment, and vehicles with heavy audio or electronic loads.

• Fifteen times more vibration resistance than typical flooded batteries
• Sealed case prevents acid leaks and corrosion in tough conditions
• Compact dimensions (9 5/16" x 5 1/16" x 8 15/16") and 26 lb weight for easier handling and fitment
• Suitable for repeated deep discharges and recharge cycles

Who is this for? The OPTIMA® YELLOWTOP DS46B24R fits drivers and operators who need a single battery to both start engines reliably and power high-draw accessories—car audio enthusiasts, off-roaders, commercial vehicle operators, and owners of tractors, forklifts, or equipment that demand dependable deep-cycle performance. Its sealed, maintenance-free design also appeals to anyone seeking long life, reduced upkeep, and flexible mounting in tight engine bays.
