Battery Tender 25-Foot SAE Extension Cable — 25ft Quick-Disconnect Charger Extension for Motorcycle, Car & ATV, Long-Reach Conveni

Battery Tender’s 25-foot SAE extension cable adds 25 feet of quick-disconnect reach to compatible Battery Tender chargers for easier, worry-free charging of vehicles parked away from outlets.

This long-reach SAE adapter gives you the flexibility to place your charger in a garage, workshop, or inside a house while keeping the battery connection on a motorcycle, car, ATV, or other equipment. Built to work with many Battery Tender charger models, the 25-foot harness eliminates awkward cable routing and lets you maintain and charge batteries without moving the vehicle or charger.

Which chargers and batteries work with this 25-foot extension?

The extension is designed for Battery Tender chargers that use standard SAE quick-disconnect plugs, such as Junior, Plus, and multi-bank units (2-, 4-, 5-, and 10-bank models). It is not compatible with Battery Tender models that use white quick-disconnect plugs, hard-wired alligator clips, or 6-volt Battery Tender Plus units. Verify your charger’s connector style before purchase.

• Compatible: Battery Tender Junior, Plus, and 2/4/5/10-bank chargers
• Not compatible: models with white quick-disconnect plugs
• Not for use with hard-wired clip-only chargers
• Check your charger connector shape and color before attaching

How does the quick-disconnect feature simplify charging?

The quick-disconnect design makes daily use and storage much easier: attach the SAE plug to your vehicle and leave it in place; then plug in the charger when needed without crawling around the vehicle. This reduces wear on exposed clips and makes seasonal or maintenance charging fast and convenient.

• Attach once to the vehicle, then connect the charger quickly
• Reduces repeated clip-on/cut-off wear to battery terminals
• Helps keep connections clean and accessible in storage
• Saves time when charging multiple vehicles sequentially

Will this extension affect charging performance or safety?

When used with compatible Battery Tender chargers, the extension maintains safe charging performance across its length; it’s engineered for low voltage drop and reliable contact. Always follow the charger’s instructions for ambient temperature, ventilation, and correct connector use to ensure safe operation.

• Designed to preserve proper charge delivery when paired correctly
• Use only with recommended Battery Tender models to avoid incompatibility
• Avoid pinched or frayed routing to maintain safety and conductivity
• Store cable neatly to prevent kinks and connector damage

What are practical ways to use a 25-foot lead around my garage or property?

The extra length lets you keep the charger near a power outlet while the vehicle sits inside a garage, across a driveway, or on a trailer. It also enables centralized charging for multiple vehicles when paired with a multi-bank charger or multiple quick-disconnect harnesses.

• Route cable through a garage door gap without moving the vehicle
• Charge bikes parked on lifts or away from outlets
• Use with multi-bank chargers for a central charging station
• Keep the charger indoors for weather protection while charging outside

Who is this for: The Battery Tender 25-foot SAE extension cable suits mechanics, hobbyists, fleet owners, and anyone who needs flexible charging access for motorcycles, cars, ATVs, snowmobiles, or lawn equipment. It’s ideal if your outlet is far from the vehicle or you want to leave a quick-disconnect on the battery for fast, repeatable charging without repositioning vehicles or running unsafe temporary wiring.
