Description

The Optima RedTop 9020-164 is a Group 35 AGM battery engineered to provide a strong burst of ignition power for reliable start-ups. It is ideal for daily-driven cars and work trucks that demand consistent performance. This battery utilizes SPIRALCELL TECHNOLOGY, which utilizes 99.99% pure lead to deliver more power and outperform conventional flat-plate batteries. This battery offers significant advantages over standard flooded batteries, including up to 3 times longer life and 15 times greater vibration resistance. Its completely non-spillable design allows for mounting in multiple positions, and it is maintenance-free for maximum convenience. Key specifications include 720 CCA, a 90-minute reserve capacity at 25 Amps, and a C20 capacity of 44.0 AH. The battery measures 9.38" long, 6.75" wide, and 7.69" high, weighing 31.7 pounds. This battery is specifically designed for the Group 35 battery size and fits a range of vehicles including the Mitsubishi Evolution VIII/IX/X (2003-2015), Subaru WRX (2002-2023), STi (2004-2021), BRZ (2013-2023), Nissan 350Z (2003-2008), 370Z (2009-2020), and Toyota Supra MK3/MK4 (1986-1998), among others.
