Deal Details
Amazon has NOCO GENIUS5: 5-Amp 6V / 12V Automatic Smart Battery Charger & Maintainer for $55.96. Shipping is free.

Thanks to Deal Hunter phoinix for finding this deal.

Product Description:
  • 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 5A 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.

Seems like it. Battery Tender seems like a basic battery maintainer that's either charginging or charged. Noco tells you if it's charging, how much (25/50/75/100%), if it's optimizing the battery cells after charging, adjusts for surrounding temps. It also has force mode for charging a completely dead (0v) battery. Noco seems like the much better deal and I'm familiar w their brand from their jump starters. Project Farm on youtube just re-certified their 155X jump starter as the reigning champion after the last tests from years ago.

For people who want to revitalize their batteries revive them even I would highly recommend Battery Minder charger products. They also have a desulfation mode, and it's better than other desulfators
