Battery Tender 12 Foot Extension SAE Cable

Battery Tender's 12.5-foot SAE extension cable increases the distance between your Battery Tender charger and battery with a quick-disconnect plug for easy, reliable connections.

If your charger needs to stay outside the vehicle or reach a battery tucked in a tight compartment, this extension adds room to work without modifying wiring. Designed to pair with many Battery Tender charging units, the cable preserves the original quick-connect system so you can plug in and leave your vehicle to charge safely and conveniently.

How does this extension make charging more convenient?

The extension keeps your charger in a convenient, accessible spot while letting the charging leads reach the battery terminals. Instead of positioning the charger next to the battery, you can mount or place it on a workbench, on a wall hook, or in a storage area.

• Adds 12.5 feet of reach between charger and battery for flexible placement.
• Maintains standard Battery Tender quick-disconnect interface for seamless use.
• Helps keep the charger away from dirt, water, or engine heat while charging.

Which Battery Tender units are compatible with this cable?

This extension is built to work with most Battery Tender products that use the SAE-style quick-disconnect plug. It is not universal for every model, so check your charger’s connector type before buying.

• Compatible with many Battery Tender Junior, Plus, and multi-bank chargers.
• Not compatible with units that have hard-wired clips or white quick-disconnect plugs.
• Works with single- and multi-bank chargers that use the standard SAE plug.

Is the cable safe to use outdoors or on different vehicle types?

The cable is intended for general charging use across motorcycles, cars, ATVs, lawn tractors and other lead-acid battery applications that match the connector style. While it provides convenience and added reach, follow your charger’s safety guidelines and keep connections dry and secure.

• Use with compatible Battery Tender chargers and factory-recommended procedures.
• Keep quick-disconnects free of corrosion and moisture for reliable performance.
• Not designed to replace permanent wiring or for continuous outdoor exposure without protection.

How do I choose the right length or number of extensions for multiple vehicles?

Battery Tender makes this extension in different lengths and multipack options so you can pick what fits your garage or fleet. Consider layout, charger location, and whether you want a spare cable for a second vehicle.

• Available in 6, 12.5, and 25-foot lengths to suit varied setups.
• Multipacks (four-pack) are offered for charging several vehicles or keeping extras on hand.
• Measure from charger location to battery terminals before buying to ensure proper length.

Who is this for: This SAE quick-disconnect extension is ideal for vehicle owners and hobbyists who use Battery Tender chargers and need extra reach—motorcycle riders, classic car keepers, ATV owners, and anyone with batteries stored in tight or hard-to-access places. Choose this cable when you want a straightforward way to position your charger safely while maintaining the convenient plug-and-play experience of Battery Tender equipment.
