Product Description
The Only Battery Charger You'll Ever Need
Tired of guessing whether your battery is dead, dying, or just needs a little TLC? The NOCO GENIUS10 takes the guesswork out completely. Plug it in, clip it on, and let it do the thinking — no manuals, no settings to memorize, no risk of frying your battery.
This 10-amp smart charger handles both 6-volt and 12-volt batteries, and it's built for just about anything with a battery: cars, trucks, RVs, boats, motorcycles, ATVs, lawn mowers, and classic cars sitting in storage. Whether you're topping off a daily driver or babysitting a diesel truck fleet over a long weekend, the GENIUS10 keeps every battery ready to go.
Works With the Battery You've Got
Lead-acid, AGM, gel, flooded, maintenance-free, EFB — the GENIUS10 charges them all. It also includes a dedicated lithium mode for 12V LiFePO4 batteries with a built-in BMS, so you don't need a separate charger for your lithium setup.
- Cars, trucks, and SUVs
- Motorcycles, ATVs, and UTVs
- Boats, jet skis, and RVs
- Lawn equipment, tractors, and golf carts
Brings Old Batteries Back to Life
Batteries that sit too long often suffer from sulfation — a buildup that kills performance and shortens their lifespan. The GENIUS10 detects this automatically and runs a repair cycle to reverse the damage, so you get stronger starts and more years out of the battery you already own instead of buying a new one.
Even a battery that's dropped to zero volts isn't necessarily a lost cause. Force Mode lets you manually kick-start the charge on a completely dead battery that a standard charger would simply give up on.
Set It, Forget It, Trust It
Once your battery's fully charged, the GENIUS10 doesn't shut off — it switches into maintenance mode and keeps monitoring the battery indefinitely. That means you can leave it connected all winter without worrying about overcharging. A built-in temperature sensor adjusts the charge automatically, so it performs exactly as it should whether it's parked in a hot garage or a freezing barn.
It's also built to handle the occasional mistake. Reverse-polarity, short-circuit, and spark-proof protection mean you can connect the clamps without stressing over which one goes where.

Frequently Asked Questions
Is the NOCO GENIUS10 a jump starter?
A: No — the GENIUS10 is a battery charger and maintainer, not a jump starter. It's designed to charge and maintain a battery over time, not deliver an instant jump to a dead vehicle.
Can I use the GENIUS10 on a lithium battery?
A: Yes, as long as your 12V lithium (LiFePO4) battery has a built-in battery management system (BMS). The GENIUS10 has a dedicated lithium mode that uses the correct charge settings for that chemistry.
Is it safe to leave the charger connected for weeks at a time?
A: Yes. Once your battery reaches full charge, the GENIUS10 automatically switches to maintenance mode and monitors the battery indefinitely, making it ideal for vehicles in storage or fleet trucks sitting idle over the weekend.
What does it mean if the charger shows no lights?
A: No lights usually means a loose connection or a battery reading below 1 volt, which requires Force Mode to begin charging. Double-check that both clamps have a solid connection to the terminals before troubleshooting further.
What size batteries can the GENIUS10 handle?
A: It's built for batteries up to 230 amp-hours and works well on everything from small powersport batteries to larger automotive and marine batteries.

Customer Reviews
This battery charger does everything I wanted it to do and more. It handles every type of battery including the newest LiFePhos batteries. I have purchased many products from Battery Mart. I have never been dissatisfied.
This is a wonderful charger. I needed a second charger so I could charge both batteries in my boat at the same time on camping trips as well as to charge my tractor battery when needed. This is way nicer than my previous NOCO charger (which I really love still), and I’d buy it again in a second. Batterymart was easy to shop, quick to shop and pricing was amazing. Shipped it to me right away and had it quicker than promised. These are the guys to go to and NOCO has the best products out there not just for the money but overall the best anyway!
Impressed with the apparent quality of this charger. Everything from the packaging to the design shows thought put into convenience of use and rugged construction. Clamps & wires are nice heavy gauge. Really like the ability to change the clamps to semi permanently ring mount cable to battery and the weather proof cap at the cable disconnect shows someone actually thought through the real world use conditions.
The only thing I would have improved is to have a larger plate for wall mounting that the charger could slide or clip into instead of the strap provided. NOCO could even make this an option since not everyone is going to want to permanently mount theirs.
