Battery Cleaner and Acid Dectector 12.25 oz

The NOCO Battery Cleaner and Acid Detector 12.25 oz is an essential maintenance tool for any mechanic or automotive enthusiast working on vehicle electrical systems. Battery corrosion and acid buildup are among the most common culprits behind starting failures, poor charging performance, and accelerated terminal degradation. This specialized formula targets both visible and hidden corrosion on battery terminals, cable connectors, and surrounding hardware—restoring electrical conductivity and preventing voltage drop that can compromise engine cranking power and accessory function.

NOCO engineered this formula with an integrated acid detector that changes color in the presence of battery acid, allowing you to identify corrosion problems before they cause catastrophic electrical faults. The cleaner dissolves lead oxide, copper oxide, and sulfate deposits without requiring scrubbing or abrasive wire brushing—critical for protecting modern vehicle electronics and sensitive engine control modules during terminal maintenance. The 12.25 oz container delivers controlled application through a precision spray nozzle, ensuring you can reach tight spaces around battery posts and cable lugs without oversaturation or waste.

Technicians and DIY builders alike benefit from this product whether troubleshooting chronic no-start conditions, performing scheduled maintenance on fleet vehicles, or rebuilding modified electrical systems after engine swaps or battery relocations. It works on both 12V and 24V systems, making it versatile for various applications, including automotive, marine, and power equipment.
