Battery Doc Fuse

Battery Doc Fuses: Reliable Circuit Protection for Every Application

When it comes to protecting your vehicle's electrical system, few names carry the depth of expertise that Battery Doc brings to the table. Manufactured by WirthCo® Engineering, Battery Doc has been delivering high-quality battery accessories made in the United States since 1980, with heavy-duty ratings and durability built into every product. That decades-long commitment to American craftsmanship is evident across their full lineup of fuses — purpose-built for automotive, marine, RV, and industrial applications.

A Fuse for Every Circuit

Battery Doc's electrical fuse line includes multiple sizes and styles of blade fuses, low-profile fuses, AGC and SFE glass fuses, Fast Acting limiter fuses, and Fast Acting MiniDoc™ automotive limiter fuses. This breadth of coverage means that whether you're protecting a standard passenger car circuit, a high-current marine power feed, or a custom RV electrical build, Battery Doc offers a purpose-matched solution.

Blade fuses feature a plastic body and two metal prongs inserted into sockets — also known as spade or plug-in fuses, they are primarily used in automobiles and can be mounted in fuse blocks, inline fuse holders, and fuse clips. Blade fuses come in a range of sizes and amp ratings, and are printed with the rated current in amps on top; many blade fuses also use a common color-coding scheme for ease of identification. Battery Doc's lineup extends this classic format with their proprietary MidBlade™ fuses, which are designed to replace standard ATO/ATC fuses, and the compact MiniDoc™ Fast Acting limiter fuses engineered specifically for automotive applications.

Fuse Assortment Kits

One of the most practical offerings in the Battery Doc fuse range is their selection of ready-to-go assortment kits. Battery Doc fuse assortments are available in 6-piece, 42-piece, and 80-piece kits. The 6-piece kits include blade fuses in six different amp ratings, the 42-piece kits include blade fuses in six different amp ratings (seven of each) along with a fuse tester/puller, and the 80-piece kits include blade fuses in eight different amp ratings with ten of each. Having a well-stocked assortment on hand means you're prepared for a blown fuse whether you're in the garage, on the road, or out on the water.

Built for Automotive, Marine, and RV Use

Battery Doc's selection of battery and circuit components offers solutions to protect against overcurrent, theft, and battery drain — ensuring the reliability, safety, efficiency, and energy of your battery system. Their fuse-related accessories, including fuse blocks, are designed for 12V and 24V vehicular electrical systems and are suitable for RVs, watercraft, cars, and more. This cross-platform compatibility makes Battery Doc fuses a smart choice for owners who work across multiple vehicles and platforms.
