    High-performance starter batteries must deliver reliable, high-current bursts under demanding conditions without premature failure. The Optima Red Top 8002-250 is a 12V AGM starter battery engineered specifically for high-draw cranking applications, offering 815 CCA (EN) and 50Ah capacity within a compact footprint suitable for modified, tuned, and performance vehicles. Optima's spiral-cell AGM (Absorbent Glass Mat) construction eliminates free electrolyte, binding the acid within glass mat separators. This design reduces internal resistance, improves charge acceptance, and delivers a strong, consistent cranking pulse even after repeated deep discharges - characteristics that conventional flooded batteries cannot match reliably over time." The 8002-250 measures 254mm x- 175mm - 200mm (L x- W x- H) and weighs 18kg. It uses a SAE Post terminal (Terminal Position 1) with top-post polarity configuration (Polarity 1) and B00 hold-down classification. No direct cross-reference is provided; fitment should be confirmed against vehicle specifications. Start-stop technology compatibility is supported by the AGM construction - verify against the vehicle's specific requirement via the product label before installation. This product is available as a single unit. No additional variants are offered within this listing. The Optima Red Top 8002-250 is covered by a 2-year manufacturer warranty against defects in materials and workmanship. " .

Frequently Asked Questions

Q1- What is the cold cranking amp (CCA) rating of the Optima Red Top 8002-250?
ANS- The Optima Red Top 8002-250 is rated at 815 Cold Cranking Amps (CCA) measured to the EN standard, making it well suited to high-compression and performance engines that demand strong, sustained cranking current.

Q2- What are the dimensions and weight of this battery?
ANS- The 8002-250 measures 254mm in length, 175mm in width, and 200mm in height including the terminal. It weighs 18kg. These dimensions should be verified against the available battery tray space before purchase.

Q3- What terminal type and polarity does the Optima Red Top 8002-250 use?
ANS- This battery uses SAE Post terminals (Terminal Position 1) with a Polarity 1 configuration, meaning the positive terminal is positioned on the right when viewed from the front of the battery. Confirm compatibility with your vehicle's cable layout before ordering.

Q4- Is the Optima Red Top 8002-250 compatible with start-stop vehicles?
ANS- The AGM construction of this battery technically supports start-stop functionality. However, compatibility must be verified against your specific vehicle's requirements. Please check the product label and your vehicle manufacturer's specification before installation.

Q5- What hold-down classification does this battery use?
ANS- The Optima Red Top 8002-250 uses a B00 hold-down classification. This refers to the base ledge profile used to secure the battery within the tray. Verify that your vehicle's battery tray accommodates the B00 configuration prior to fitting.

Q6- What is AGM battery technology and why does it benefit starter applications?
ANS- AGM stands for Absorbent Glass Mat. The electrolyte is immobilised within fibreglass separators rather than left free to pool as in conventional flooded batteries. This construction lowers internal resistance, improves charge acceptance, and provides more consistent high-current delivery during cranking - particularly beneficial in high-performance and modified vehicles.

Q7- What is the capacity of this battery?
ANS- The Optima Red Top 8002-250 has a rated capacity of 50Ah measured at the C20 rate. Capacity figures at C5, C10, and C100 rates are not published for this product. For the majority of automotive starter applications, the C20 rating and CCA figure are the most relevant specifications.
