Deal Details
Amazon Resale via Amazon has NOCO Genius10 10-Amp 6V & 12V Fully-Automatic Smart Battery Charger & Maintainer (Used: Like New) for $53.16. Shipping is free.

Thanks to Deal Hunter phoinix for sharing this deal.

Product Description:
  • Similar to our G7200, just better. It's 17% smaller and delivers over 115% more power. It's the all-in-one charging solution - battery charger, battery maintainer, trickle charger, plus desulfator.
  • Designed for 6-volt and 12-volt lead-acid (AGM, Gel, SLA, VRLA) and lithium-ion (LiFePO4) batteries, including flooded, maintenance-free, deep-cycle, marine and powersport batteries.
  • An integrated thermal sensor dynamically adjusts the charge based on ambient temperature, preventing overcharging in hot weather and undercharging in cold, ensuring optimal battery performance.
  • Charge batteries from as low as 1 volt, or use Force Mode to manually charge completely dead batteries down to zero volts. Perfect for recovering deeply discharged or neglected batteries.
  • Keep your battery fully charged without worrying about overcharging. Our smart charger constantly monitors the battery, allowing you to leave it connected safely - indefinitely - for worry-free maintenance.
  • Precision pulse charging automatically detects and reverses battery sulfation and acid stratification, restoring your battery's health for improved performance and extended lifespan.
  • Charges and maintains all types of vehicles, including cars, automobiles, motorcycles, mopeds, lawn mowers, ATVs, UTVs, tractors, trucks, SUVs, RVs, campers, trailers, boats, PWCs, jet skis, classic cars, and more..
  • Includes a 10A charger, 72-inch AC cable, 80-inch DC cable with battery clamps, and integrated eyelet terminals, mounting bracket, screws, and a 3-year warranty. Proudly designed in the USA.

This is a good deal. I'd buy it, but I got the $36 Gearwrench 10 amp charger deal. This one is better since it reverses sulfation which the Gearwrench does not.

Why buy used when you can snag a new one (different brand, but basically same) for less?

This charger goes very quickly to green, then takes a long time to float. Most chargers allow you to see the progression from one stage to another, not this one. Just bought a BatteryMinder and I love it.

Maybe, but when you know that a battery has a very low charge you like to see the stage progression and desulfating. I've had so many chargers and this is the only one that goes to green when you know that it's not fully charged.

The charger has four distinct charge progress LEDs (24%, 50%, 75%, and 100%) that change colors based on the battery's state of charge: [1] (https://www.youtube.com/watch?v=T0-2mK-5_es), [2] (https://no.co/support/genius10)Pulsing Red (First LED): The battery is less than 25% charged. [1] (https://no.co/support/genius10)Pulsing Red (Second LED): The battery is less than 50% charged. [1] (https://no.co/support/genius10)Pulsing Orange (Third LED): The battery is less than 75% charged. [1] (https://no.co/support/genius10)Pulsing Green (Fourth LED): Bulk charging is complete. The charger is now optimizing the battery for extended life. It is completely normal for this light to pulse for a long time. [1] (https://no.co/support/genius10), [2] (https://www.youtube.com/watch?v=T...5_es)Solid Green: The battery is 100% fully charged and optimized. All other tracking LEDs will turn off. [1] (https://www.youtube.com/watch?v=T0-2mK-5_es)Slow Pulsing Green: The charger has entered Maintenance Mode. It will safely provide ongoing optimization indefinitely until you unplug it.

I own one of these, the NOCO 5, and they're like a Godsend if you accidentally drain your car battery. Ask me how I know 🤦🏾 ♂️🙄🤷🏾 ♂️

I have this and haven't had that issue. Used the desulfating mode (which is a different setting from standard charging) on my in-laws car which had sat for months, and the charger showed the process moving slowly through the four LEDs. The same thing happens when charging in standard mode. When the green light does start to blink, it can do it for quite a while before going solid, indicating full charge.
