TOPDC 22in Fused Ring Terminal Harness 6-Pack — Quick-Connect Leads with 10A Fuse and Protective Caps

TOPDC's 22-inch fused ring terminal harness is a six-piece quick-connect extension set that lets you attach battery chargers and maintainers securely to hard-to-reach battery posts.

This compact accessory bundle gives you long, flexible leads with pre-installed ring terminals and a 10A inline fuse so you can hook up chargers without crawling into tight engine bays or repeatedly stripping and re-clamping clips. Each harness is built from SPT-2 18AWG/2C cable and includes a protective end cap to shield the connector when it's not in use. The six-piece set covers multiple vehicles and battery types, making it a practical addition to a garage, workshop, or emergency kit.

How will this harness make connecting a charger easier?

The 22" cable extends reach so you can bolt the ring terminal to the battery post and leave the quick-connect lead accessible for repeated connections. The ring terminal fits posts up to 0.425" (10.8 mm) inside diameter, removing the need to wrestle a clip into place each time. The attached end cap keeps the quick-connect clean when not attached.

• Extra 22" cable length for easier access to recessed batteries
• Ring terminal with 0.425" (10.8 mm) inside diameter for secure bolting
• Protective cap prevents corrosion and dirt buildup
• Quick-connect end for fast charger attachment and removal

Is it safe to use with my charger or maintainer?

Each harness includes a 10 Amp inline fuse to protect against excessive current draw, making it suitable for chargers and maintainers that operate below 10 amps. The SPT-2 18AWG/2C cable is ETL listed for general-purpose use, and the ring terminal design ensures a stable mechanical connection to the battery post. Always check your charger’s specifications and fuse requirements before use.

• 10A inline fuse included for basic overcurrent protection
• ETL-listed SPT-2 18AWG/2C cable for standard charging applications
• Secure bolted connection minimizes arcing and loose contacts
• Not intended for applications exceeding 10 amps continuous

Which vehicles and batteries are compatible with these leads?

The harnesses are designed for broad compatibility: they work with car, motorcycle, boat, RV, lawn and garden, and small power tool battery systems that accept a ring terminal connection and draw under 10 amps. Because each piece is 22" long and supplied in a six-pack, you can outfit several vehicles or keep spares for seasonal equipment. The design keeps chargers accessible without altering wiring on the vehicle itself.

• Automotive and motorcycle batteries with standard posts
• Marine and RV batteries for seasonal charging and maintenance
• Lawn, garden, and small power tool battery systems
• Useful for multi-vehicle garages or equipment fleets

How durable and maintenance-friendly is the set?

The harness uses flexible SPT-2 cable that resists kinking and stands up to repeated handling. Ring terminals are sized to accept common battery post bolts and are less likely to loosen than spring clips. The included end caps protect the quick-connect plug from moisture and debris, extending service life between cleanings.

• Flexible, kink-resistant SPT-2 18AWG cable for regular use
• Robust ring terminals for reliable bolted connections
• End caps block moisture and dirt from the quick-connect plug
• Six-piece pack reduces wear by rotating harnesses across batteries

Who is this for: The TOPDC 22" 10A fused ring terminal harness set suits DIY mechanics, fleet managers, boat owners, RV enthusiasts, and anyone who needs a neat, safe way to leave charger leads attached to batteries for regular maintenance. It’s best for systems drawing under 10 amps and for users who prefer quick-connect convenience without modifying factory wiring.
