Bought this after my mower battery died twice last spring. Should've done it years ago.

Figured I'd just keep using jumper cables. Turns out there's a better way. I hook the GENIUS1 up to my boat when it goes into storage, and it just handles everything. Haven't touched my jumper cables since October. . Dan M., Lake Havasu City, AZ·4.8 out of 5

Didn't realize it would tell me my old mower battery was shot before I wasted time on it.

If you own a boat or motorcycle that sits for weeks, get this. Solved my dead battery problem completely.

Mark T. My neighbor kept asking to borrow jumper cables for his bass boat. Finally told him to just get one of these instead. He did, and now his trolling motor battery stays ready all winter. Perfect for anyone with seasonal stuff that sits in the garage between uses. Way better than replacing batteries every spring.

Ready to start on the first try

Jumper cables only rescue a dead battery after it strands you. They can't prevent sulfation, can't stop capacity loss, and leave you hoping someone's around to give you a jump.

How It Works

Automatic Charging That Adapts to Your Battery

The NOCO GENIUS1 monitors your battery's condition and adjusts its charge rate based on temperature. In summer heat, it prevents overcharging that cooks battery cells. In winter cold, it compensates for sluggish chemistry that leaves batteries undercharged. You connect it once, select the correct mode for your battery type, and walk away. The charger handles flooded, gel, AGM, maintenance-free, and 12V lithium batteries automatically. It works on 6V and 12V systems, so the same compact unit maintains your car, motorcycle, riding mower, boat, ATV, or RV. Built-in diagnostics warn you of reverse polarity, high voltage, or a damaged battery before you have a problem.

The Real Cost

First Warm Day. Dead Battery. Sitting Kills

Your motorcycle waits all winter. Spring finally arrives, and you turn the key to silence. The battery drained while it sat. Now you're digging out jumper cables, calling for a jump, or buying yet another replacement battery. Jumper cables solve the symptom after it happens. They do nothing to prevent it.

Battery Maintenance Without Constant Babysitting

Attach the clamps or integrated eyelets, select your battery type, and press the button. The GENIUS1 charges your battery to full, then switches to maintenance mode automatically. It stays connected for weeks or months, keeping the battery at optimal charge without overcharging. The compact housing fits in a glovebox or tool drawer. When you want to ride, drive, or mow, the battery is ready.
