ATV, SXS, and UTV batteries live in tight compartments where stacking ring terminals on a single post is the default solution and the source of most corrosion problems. Stacked terminals trap moisture, add resistance, and make every service job harder than it needs to be. The Terminal Tender™ family of battery post expansion blocks solves that problem with a rigid block that bolts to the battery post and gives you multiple threaded studs to land terminals on. The result is a clean install for any quick connect battery setup, battery tender connector, accessory wire, or charger lead you want to add to the machine.
Here, you’ll find the Terminal Tender™ in two configurations:
Terminal Tender™ Battery Post Expansion Blocks: the standard expansion block for SAE-style battery posts. Adds multiple secure connection points for accessory wiring.
Terminal Tender™ for Round Post Batteries: the same expansion approach sized for round-post marine and ATV batteries.
Every accessory you add (chargers, electronics, fishfinders, lights, a battery quick connect for trickle charging) needs a place to land on the battery posts. Stacking terminals on top of each other works once or twice, then turns into a corroded, intermittent mess. The Terminal Tender™ block bolts to the post once and gives you clean, accessible threaded studs for every connection. Service is faster, corrosion is dramatically reduced, and adding a new accessory doesn’t mean rebuilding the whole stack.
Match the Terminal Tender™ to your battery post style. SAE-style standard posts use the standard expansion block; round-post batteries use the dedicated round-post version. Owners running mixed banks (one of each) should order both. The Terminal Tender™ installs once and stays installed; plan one per battery post that has more than two accessory connections, including any battery quick connect for trickle charging.
