Choosing battery cable is not just about picking a thick wire. You also need the right conductor material, insulation, length, and gauge for your electrical load. The Shirbly 2 AWG Battery Cable 10FT Red+Black combines pure copper conductors with upgraded double-layer EPDM insulation and a 600V rating. Its strongest points are flexible 1070-strand construction and a wide temperature rating, but you still need to confirm that 2 AWG is correctly sized for your specific circuit before installation.
Quick Verdict
Rating: 8.5/10, Recommended with caveats
Best For: Automotive battery wiring, generator projects, solar installations, and other properly engineered DC cable runs that call for 2 AWG copper cable.
Bottom Line: You get 10 feet of red cable and 10 feet of black cable with fine-stranded copper and tougher double-layer EPDM insulation. The main limitation is that a 600V insulation rating does not tell you the safe current for every installation, so cable sizing must still match your load, run length, connections, and protection device.

What Is the Shirbly 2 AWG Battery Cable?
The Shirbly cable is a 2 AWG fine-stranded copper power cable set supplied as one 10-foot red length and one 10-foot black length. The color pairing is useful for keeping positive and negative cable runs visually separated in battery, generator, solar, and other DC installations.
The conductor uses 1070 strands of 0.2 mm copper wire. Fine stranding helps the cable bend more easily than a stiff solid conductor of similar overall size. Shirbly surrounds the conductor with upgraded double-layer EPDM insulation designed to improve resistance to abrasion, wear, tearing, solvents, and demanding temperatures.
Key Takeaways
- You receive 10 feet of red and 10 feet of black 2 AWG cable, giving you 20 feet of cable in total.
- The conductor is fully annealed pure copper/OFC with 1070 fine strands.
- Double-layer EPDM insulation is the main upgrade over Shirbly’s earlier single-layer design.
- The cable carries a 600V insulation rating and a stated temperature range of -58°F to +221°F.
- It is intended for automotive, battery, solar, generator, and other appropriately designed DC wiring projects.
- You still need to verify that 2 AWG is the correct cable size for your current, run length, voltage drop target, terminals, and circuit protection.
Benefits of Choosing This 2 AWG Battery Cable
The main advantage is the combination of copper conductivity and flexible strand construction. With 1070 individual strands, the cable can be routed around bends more easily than a much stiffer conductor, which can help when you are working through an engine bay, battery compartment, power cabinet, or equipment enclosure.
The red and black 10-foot lengths also make planning a paired positive and negative run easier. You can measure each route before cutting rather than buying two separate cable colors.
The upgraded insulation is another practical benefit. Shirbly specifies double-layer EPDM rather than the single-layer sheath used on its older version. The manufacturer states that the design improves wear, tear, solvent, corrosion, and abrasion resistance while maintaining flexibility.
Who Should Buy It?
Best For
- DIY or professional projects that specifically call for 2 AWG copper cable.
- Battery, generator, automotive, or solar installations needing separate red and black cable runs.
- Installations where flexible fine-stranded cable and durable EPDM insulation are useful.
Skip If
- Your equipment specification calls for a different wire gauge or conductor type.
- You need a preassembled battery cable with verified factory-installed terminals.
- You have not calculated or confirmed the correct cable size for your electrical load and run length.
Build Quality and Materials
The cable’s conductor is listed as fully annealed pure copper/OFC, not a generic conductor with unspecified metal content. For buyers comparing power cable, that distinction matters because the conductor material is one of the first specifications you should confirm.
Shirbly lists 1070 strands at 0.2 mm each for the 2 AWG version. Its A+ comparison information also lists an outside diameter of about 0.58 inch for this gauge. That thicker overall construction is worth considering before you choose lugs, cable glands, protective conduit, or routing holes.
Double-Layer EPDM Insulation
The upgraded double-layer EPDM jacket is designed for more demanding use than the company’s previous single-layer version. Shirbly describes resistance to wear, tearing, corrosion, solvents, fire, and abrasion while retaining cable flexibility.
That does not make the cable immune to poor routing. You should still keep wiring away from sharp sheet metal, moving components, exhaust parts, unprotected pinch points, and other areas that can damage insulation.
What to Expect From Performance in Extreme Conditions
Shirbly rates the cable from -58°F to +221°F (-50°C to +105°C). That gives you a broad published operating range for installations exposed to changing seasonal temperatures.
The cable is also rated at 600V. This figure describes the cable’s voltage rating. It should not be treated as a statement that the cable can safely carry any amount of current simply because your system operates below 600V.
Before You Buy: A 600V cable rating is not the same thing as an ampacity rating. Confirm the required conductor gauge using your equipment requirements, maximum current, cable length, allowable voltage drop, installation conditions, connection hardware, and required circuit protection. If you are unsure, have the system specified or checked by a qualified automotive or electrical professional.
Fit and Compatibility
This is not a vehicle-specific replacement part. A vehicle, inverter, battery bank, generator, winch, charger, or solar installation is compatible only when its electrical requirements call for a cable with the correct gauge, conductor type, voltage rating, temperature rating, and termination method.
Before ordering, measure the actual cable route rather than the straight-line distance between components. The set gives you 10 feet of red cable and 10 feet of black cable, so each individual polarity run must fit within the available length unless your design uses only part of the set.
Pro Tip: Dry-fit the full cable route before cutting. Include enough length for bends, secure fastening, and service access, but avoid leaving large loose loops that can rub against nearby parts.
How It Performs in Real Use
Automotive Battery and Power Wiring
The fine-stranded construction is useful when a cable has to follow bends through an engine bay or battery compartment. The red and black jackets also make polarity identification easier during routing and future service. You still need properly sized terminals and circuit protection for the actual installation.
Solar and Battery Bank Projects
Shirbly lists solar and high-voltage battery applications among its intended uses. In these systems, the cable’s 600V rating and copper conductor are useful specifications, but the correct wire size still depends on current, distance, system voltage, voltage drop, and applicable electrical requirements.
Generator and Equipment Connections
For generator or equipment wiring that calls for 2 AWG flexible copper cable, the double-layer EPDM jacket gives you a more protected outer surface than Shirbly’s previous single-layer version. The wide stated temperature range can also be useful where equipment sees significant seasonal temperature changes.
Workshop and Custom Power Projects
The product is also marketed as welding cable, and the flexible construction makes it suitable for custom heavy-cable projects when the electrical specifications match. For any high-current setup, the quality of the lugs, crimps, connections, and protection devices matters just as much as the cable itself.
Installation and Usage Tips
- Measure first: Confirm both positive and negative routing lengths before cutting either 10-foot cable.
- Match the terminals: Choose lugs and connectors designed for 2 AWG cable and for the studs or connection points on your equipment.
- Use a proper crimp: Loose or poorly made high-current connections can create unwanted resistance and heat.
- Protect the cable: Keep the insulation away from sharp edges, hot exhaust components, moving parts, and locations where it may be crushed.
- Secure the run: Support the cable so vibration and movement do not repeatedly flex the same connection point.
- Use appropriate circuit protection: Follow the equipment manufacturer’s requirements and applicable electrical practices for fuses, breakers, and disconnects.
- Inspect before energizing: Check polarity, crimps, exposed conductor, fastener tightness, routing, and insulation condition before powering the circuit.
Compatibility and Safety
Heavy battery cable can carry substantial electrical energy when connected to a battery or power source. Disconnect and isolate the power source before cutting, crimping, routing, or servicing cable, and follow the instructions supplied with your battery, inverter, generator, vehicle, charger, or other equipment.
Do not select 2 AWG solely because it appears heavy enough. Undersized conductors, incorrect protection, damaged insulation, loose connections, and reversed polarity can create serious electrical problems. For installations you are not trained to size or terminate, professional installation is the safer choice.
Pros and Cons

Is It Worth the Price?
The Shirbly 2 AWG cable makes the strongest value case when you specifically need fine-stranded pure copper cable with a tougher double-layer EPDM jacket. You receive matching red and black 10-foot lengths, which can save you from sourcing each polarity separately.
Its value depends less on the lowest purchase price and more on whether its gauge, length, and construction match your project. It is worth considering if those specifications fit your installation. It is not a smart buy simply because it is a heavy cable if your system actually requires a different gauge, cable length, or finished terminal configuration.
How It Compares to Alternatives
The most direct comparison is Shirbly’s earlier 2 AWG design. The reviewed version uses the newer double-layer EPDM insulation, while Shirbly describes the previous design as using a single-layer sheath. The upgrade is aimed at improving wear, tear, corrosion, solvent, and abrasion resistance.
Shirbly also sells other gauges in the upgraded cable family, including 6 AWG, 4 AWG, 1/0 AWG, and 2/0 AWG options. Do not select a larger or smaller gauge simply because it costs more or less. Your equipment requirements, maximum current, cable length, voltage drop, and installation conditions should determine the correct size.
Customer Support and Warranty: What You Need to Know
Shirbly states that 24/7 customer support is available and advises buyers to inspect the product after delivery and contact the company if there is a problem.
A specific warranty period is not clearly stated in the verified listing reviewed for this article. If warranty coverage matters to your purchase, check the current Amazon listing, seller terms, and manufacturer information before ordering rather than assuming a particular coverage period.
Frequently Asked Questions
How much cable is included?
The verified configuration includes one 10-foot red cable and one 10-foot black cable. That gives you 20 feet combined, but each individual color is limited to 10 feet.
Is the Shirbly 2 AWG cable pure copper?
Yes. The Amazon listing describes the conductor as fully annealed pure copper/OFC and specifies 1070 strands of 0.2 mm copper wire for the 2 AWG version.
Can you use this cable in a solar power system?
Shirbly lists solar systems among the intended applications. You should still confirm that 2 AWG, the 600V cable rating, cable length, and termination method meet the electrical requirements of your particular solar installation.
What vehicles are compatible with 2 AWG battery cable?
The cable is not tied to a specific vehicle model. Compatibility depends on the vehicle or accessory’s electrical requirements, current demand, cable length, voltage drop, connection size, routing, and required protection.
Does the 600V rating tell you how much current the cable can carry?
No. The 600V figure is the cable’s stated voltage rating. Safe conductor sizing also depends on current, run length, allowable voltage drop, temperature, installation method, connection hardware, and applicable equipment or electrical requirements.
Is the cable flexible enough for tight routing?
The 1070-strand construction is designed to remain flexible, and Shirbly specifically states that the double-layer EPDM upgrade maintains flexibility. You should still respect bend space and avoid forcing the cable into sharp corners that stress the conductor or terminals.
Can it be used in very hot or cold conditions?
The manufacturer states a temperature rating from -58°F to +221°F (-50°C to +105°C). Your complete installation must still stay within the limits of every connected component and should be routed away from direct heat sources that exceed its rating.
What warranty does the Shirbly cable have?
The verified listing states that Shirbly provides 24/7 customer support, but it does not clearly specify a fixed warranty period. Check the current product and seller terms before purchase if warranty length is important to you.
The Bottom Line
The Shirbly 2 AWG Battery Cable 10FT Red+Black is a solid choice when your project specifically needs flexible 2 AWG pure copper cable, separate red and black 10-foot runs, and durable double-layer EPDM insulation. Its verified 1070-strand conductor, 600V rating, and -58°F to +221°F temperature range are meaningful strengths, but you should skip it if your electrical calculations or equipment requirements call for a different cable size or finished cable assembly.
