Optima Battery 34/78 Red Top High Performance Start 12V AGM 800 CCA | Left Positive

Optima 34/78 RedTop High Performance Starting Battery – 12V AGM 800 CCA (LHP)

The Optima 34/78 RedTop is a high-performance 12V AGM starting battery built for vehicles that demand instant starting power and long-term reliability, making it an ideal choice for Boss Air Suspension–equipped vehicles, 4WDs, and performance builds running onboard air compressors and electrical accessories.

Producing a strong 800 Cold Cranking Amps (CCA), the 34/78 RedTop delivers fast, confident engine starts while maintaining stable voltage for air suspension systems and compressor operation. Its Left-Hand Positive (LHP) configuration, combined with both top SAE terminals and side terminals, provides exceptional installation flexibility across a wide range of vehicles.

Designed for Air Suspension & Onboard Air Systems

Air suspension and onboard air systems place immediate electrical demand on a vehicle after start-up. The Optima RedTop’s AGM SpiralCell design delivers clean, consistent power to support compressor engagement, air tank refill cycles, and air management systems without voltage drop.

This makes the 34/78 RedTop especially well suited to:

• Vehicles running Boss Air Suspension

• Onboard 12V air compressors and air tanks

• Custom engine bay or relocated battery setups

• Performance street cars and modified 4WDs

Dual Terminal Design for Maximum Flexibility

The 34/78 model features both SAE top posts and side terminals, allowing compatibility with a broader range of factory and aftermarket wiring layouts. This is particularly useful in custom builds, American vehicles, and installations where accessory power is required alongside the main starting circuit.

Built for Harsh Conditions

Designed to outperform conventional lead-acid batteries, the Optima 34/78 RedTop offers exceptional resistance to vibration and harsh environments. Its sealed AGM construction is maintenance-free, spill-proof, and mountable in multiple orientations, making it ideal for off-road, touring, and performance applications.
