Delivering a potent 10-amp current, this advanced micro-processed smart charger effortlessly juices up automotive, marine, deep-cycle, and powersport batteries up to twice as fast as standard legacy chargers. It offers absolute compatibility with both 6-volt and 12-volt setups, including traditional flooded lead-acid, gel, maintenance-free, EFB, AGM, and modern high-performance lithium-ion batteries, making it an incredibly versatile and sophisticated asset for any garage, workspace, or vehicle fleet. What makes this smart charger exceptionally practical for keeping vehicles completely dependable and maintaining peak electronic health is its fully automated, set-and-forget multi-stage charging architecture and onboard diagnostic suite. It features an integrated thermal sensor that dynamically samples the ambient temperature and adjusts the charging profile to prevent under-charging in bitter cold or over-charging in sweltering heat, safeguarding your vehicle's delicate internal battery cells from premature degradation. The device is equipped with a highly advanced, automated desulfation and repair mode that detects internal battery sulfation and acid stratification, actively restoring lost performance to revive dead or deeply discharged batteries. This makes it a fantastic, high-reliability tool for counteracting the parasitic battery drain common in modern, tech-heavy vehicles that sit idle or are used primarily for brief local trips, ensuring your battery voltage remains perfectly balanced, stable, and completely ready for action. Review: very much worth - brought my dead AGR battery back to life! superstar charger, my car had a 10v battery it was over £200 for a new one, so i thought i would try this first, absolutely great, took around 8 hours to bring it from 10v back to a healthy 12.7v, its quite a meaty lump of a thing, it comes with all the connections you could need, and it is small but very dense, nice and easy to use, just select battery type and go! well worth, even though it is a bit expensive i think in this case you get what you pay for ## Features - MEET THE GENIUS10UK — Similar to our G7200UK, just better.

I use it to keep two separate banks of two x 120ah batteries topped up when my solar isn’t enough. I plug it into the 240 electric and fasten it onto my inverter. My batteries were often going flat, they are always full now. This item also has the ability to bring dead batteries back to life it is an amazing product. There are also loads of accessories available to buy so that you can use it for other things. It charged my car battery up beautifully yesterday. I wish I’d had this years ago it’s well worth the money **Q: Will supply mode supply constant 10a with the battery connected? need it for flashing ecu** A: It depends if tuning the ECU requires applying a "load" (e.g., turning on lights) during reprogramming. If yes, then it's not sufficient. If no, then using the 12V Supply Mode should work, but remember not to add any loads during the process. It is also best practice to contact the manufacturer to make sure the vehicle does not draw more than 10-amps during reprogramming. **Q: Can I charge my iphone** A: For phones and other USB charged devices buy the NOCO Boost Sport or similar unit which is a combined 12v jump starter, USB supply/charger and 5 mode LED emergency torch designed to be kept in the vehicle. For camping/day trips it can be recharged with a small solar panel or from a vehicle socket as it has standard USB input and outputs. **Q: Live in a flat so my car is always parked in street or in a public car park so can't plug in to mains/connect to battery in car at same time. Suitable** A: You can remove the battery and charge it in your flat ## Customer Reviews ### ⭐⭐⭐⭐⭐ Everyoe should own one and keep their batteries in top condition *by A***W on 21 June 2026* The NOCO GENIUS10 10A 6V/12V Smart Battery Charger is an absolute powerhouse of a diagnostic and maintenance tool, masterfully engineered to bring heavy-duty charging performance and long-term battery health to a vast array of vehicles.

Although it put around 50% charge in it took 24hrs. I had two batteries to charge so purchased the Noco 10 . Not only did it finish charging the first battery in 3hrs approx The second battery again totally discharged was revived fully within 14hrs. Great tool and well worth the money. Also with the maintain function when the batteries not in regular use I can use this unit to keep the batteries fully charged ## Frequently Bought Together - NOCO GENIUS10: 10A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid & Lithium Batteries - NOCO GC004 X-Connect 3-Meter Extension Cable Accessory for NOCO Genius Smart Battery Chargers - NOCO GC002 X-Connect M6 Eyelet Terminal Accessory for Genius Smart Battery Chargers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/169905287-genius10-10a-6v-12v-smart-battery-charger-automatic-maintainer-trickle](https://www.desertcart.hr/products/169905287-genius10-10a-6v-12v-smart-battery-charger-automatic-maintainer-trickle) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-21*
