- Product Details
1 Gauge Battery Cable is made of stranded copper wire. The insulation is dural PVC. 1 ga battery cable provides a large conductive cross-section, ensuring low resistance and efficient power delivery over extended distances. Used widely in the automotive industry, renewable energy systems, and other high-load applications. 1 gauge battery wire is also know as Type SGT SAE J1127-Battery Cable.
Product features：

FAQ
How many amps can a 1 gauge battery cable handle?
In a free-air environment at 20°C, 1 Gauge copper cable is typically rated for 130A to 150A continuous current. For short bursts (like engine starting), it can handle significantly higher loads depending on the insulation temperature rating (e.g., 105°C).
What is the maximum wattage a 1 Gauge cable can handle on a 12V system?
For continuous loads, it is recommended for up to 1500W - 1800W in 12V systems to maintain a safe voltage drop (<3%). For 2000W+ inverters, upgrading to 1/0 AWG is often advised.
What is the difference between 1 AWG and 1/0 AWG battery cable?
1/0 AWG (One-Ought) is larger than 1 AWG. 1/0 AWG has a cross-section of ~53.5 mm², whereas 1 AWG is ~42.4 mm². 1/0 is capable of carrying approximately 20-30A more current.
