0 GAUGE (1/0 Size) Copper Ultra-Flex Welding Cable / Battery Cable Assembly

Made from our premium Ultra-Flex Welding Cable / Battery Cable which is pure OFC copper and Made in the USA.

Your choose your color, length and cable ends from the options above near the purchase buttons. The copper lugs (ring terminals) as well as the copper top post positive and negative battery terminals feature a tin plating which is resistant to corrosion and it superior to bare copper terminals.

The copper connectors are crimped to the battery cable using the UL approved crimping tool as specified by the manufacturer. We then seal the connection point with adhesive heat shrink tubing in the color to match the cable. The heat shrink has a melt-able glue lining to help seal your cable from air and moisture.

If you need something special with regard to the length or lugs outside the available options please send us a message and we may be able to help you out.

ABOUT THIS AWESOME BATTERY CABLE...

This Ultra-Flex battery cable is designed to be super flexible with fine OFC Copper stranding of 34 gauge strands (Class M). Featuring a proprietary TPE jacket compound which allows this cable to stay flexible over a very wide range of temperatures from -50°C (-58°F) to 105°C (221°F).

A special cable MADE IN THE USA which was specifically designed to be the extremely flexible option to all the low quality imported car audio power wire with their false claims and undocumented testing!

MORE FLEXIBLE THAN STANDARD WELDING CABLE !!!

BENEFITS OVER CCA POWER WIRE:
Our cable is Copper...REAL COPPER but watch out for other "CCA Cable" as CCA Means Copper Clad Aluminum so you'd be using Aluminum which is a poor conductor compared to this pure copper cable! You have to use larger sizes of aluminum CCA cable, approximately 2 sizes larger to get close to the same power delivery as real copper cable! If you care about maximum power use our cable!

FINAL POINTERS ON LUG SIZING
Most threaded stud batteries will have either a 5/16 or 3/8 inch stud. Most of the time the negative will be 5/16 so if the positive is the same size it is also 5/16, but if your battery stud is larger on the positive it will most likely be a 3/8. There are exceptions to the rule so please contact the manufacturer or measure. We have a bolt measuring guide in our FAQ section and Blog to help.

If you have questions about cable sizing and whether this is the correct size feel free to send us a message and we will do our best to answer you or at a minimum steer you in the right direction.

These values for current-carrying capacity are based on a copper temperature of 60°C (140°F), an ambient temperature of 40°C (104°F) and yield load factors from approximately 32% for the 2 AWG cable to approximately 23% for the 3/0 AWG cable. In actual service, the load factor may be much higher than indicated without overheating the cable as the ambient temperature will generally be substantially lower than -40°C.

Q: What if I need an assembly length not listed?

A: Order the next largest length available and add a note in the checkout for us to adjust your cable to the length you need. Example: You want 10.5ft so order an 11ft and add a note for us to make the cable 10.5ft instead.

*If you're looking for a longer length than what is available in the regular BATTERY CABLE section please go to the WIRE BY THE FOOT section and order the longer length of wire and order the connectors in the CONNECTORS section and simply add a note in the checkout for what you'd like us to assemble for you from those items.

Q: Can you turn or rotate a certain connector?

A: Yes, just order the cable as listed and in the checkout add a note telling us how you want the lug turned. Here is a chart we made to assist you in describing how to tell us to turn lugs >Lug and Terminal Turn Options

Q: Can you put a 90 degree bent lug on instead or a straight one?

A: Yes, just order the cable as listed with the straight lugs and add a note in the checkout for us to put a 90 degree bent lug on instead.

Q: Do you have cables pre-made for specific vehicles?

A: No, sadly there is no place for us to lookup the battery cable dimensions of wire size, length and end sizes on a per vehicle basis. That information is not in any readily accessible database. You'll have to get the measurements for the cables you want us to build for you before we can build them

Q: Can you add an auxiliary or extra wire in the same connector?

A: Yes, we can. At this time the way we handle it is if the extra wire is 8 AWG or larger you would order the extra wire as an assembly being sure to leave at least one end with no connector and add a note for us to put it into which ever end you tell us to. If the auxiliary wire is smaller than 8 AWG we can use a 10 AWG wire just add a note in the checkout for us to add a 10 AWG wire into whichever connector you need it in.

Q: Can you help me figure out my bolt size?

A: We have put some information together here to help >How to measure a bolt size

Q: Can you help me figure out what size cable or wire I currently have?

A: Always start by looking on the side of the wire for printing that should tell you the wire size. Sometimes there is a stamp in the connector which indicates the size as well. Different styles of stranding in the cable as well as various insulation thicknesses mean there is not a "one size fits all" exact measurement but here are measurements based on a range of typical battery cable styles as a reference. (when in doubt between wire sizes ALWAYS choose the larger wire size)

Wire Gauge Size	COPPER CONDUCTOR Diameter (no insulation)	Overall Outside Diameter with Insulation
8	0.143-0.165 inch (3.63-4.19 mm)	0.218-0.270 inch (5.54-6.86 mm)

3/0 (000)	0.485-0.510 inch (12.32-12.95mm)	0.641-0.670 inch (16.28-17.02 mm)
4/0 (0000)	0.555-0.580 inch (14.10-14.73mm)	0.695-0.741 inch (17.65-18.82 mm)

Q: What is the difference between the cable types?

A: Some people need certain specifications on cables due to codes and regulations. We've put together a cable comparison section here > Battery Cable Differences
