SAE Quick Disconnect Wiring Harness — Male & Female Copper Power Extension Cable

The SAE connector is the standard quick-disconnect interface for automotive battery maintenance, solar charging systems, and portable power applications. This male-and-female extension harness lets you extend your SAE connection point, add a charging pigtail to a battery, or create a custom disconnect point in a solar or 12V power system — all with copper conductors and a weatherproof connector body.

Technical Specifications

Key Features

• SAE J563 standard: Compatible with all SAE-standard battery tenders, solar charge controllers, and 12V accessories — universal interchangeability across brands
• Copper conductors: Tinned copper strands provide low resistance, corrosion resistance, and reliable current capacity for battery charging and solar applications
• Polarity-keyed connector: SAE connector is polarized — cannot be connected backwards, eliminating reverse-polarity damage risk
• Rubber dust cover: Female connector includes a protective rubber cap to prevent moisture and debris ingress when disconnected
• Male + female pair: Each set includes both genders — create a complete extension or add a new connection point to an existing SAE harness

Common Applications

• Battery tender / trickle charger permanent pigtail on motorcycle, ATV, or classic car battery
• Solar panel to charge controller quick-disconnect
• 12V portable power bank connection point
• Extending an existing SAE harness to reach a remote battery location
• Adding a quick-disconnect point to a custom 12V wiring harness

Frequently Asked Questions

Q: Is this compatible with Battery Tender, CTEK, and Optimate chargers?
A: Yes. All major battery tender and trickle charger brands (Battery Tender, CTEK, Optimate, Deltran) use the SAE J563 connector standard. This harness is fully compatible.

Q: What is the maximum current rating?
A: The SAE J563 connector is rated for up to 15A continuous. Actual capacity depends on the conductor gauge of the specific cable. Refer to the product images for the wire gauge specification of this listing.

Q: Can I use this for solar panel connections?
A: Yes. SAE connectors are widely used in portable solar panel systems. Ensure your solar panel output and charge controller input are both SAE-terminated, or use an SAE-to-MC4 adapter for MC4-terminated panels.
