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.

FYI these are smart chargers (maintaining, trickle charging, etc) and not jump starters.

Can you keep the battery charged while it is in the car or do you have to disconnect it while charging?

Works fine to charge/maintain in the vehicle. I've got a couple that are rarely driven ands have been using noco charger to keep them topped up for years with no issues

Would this do the job to get voltage back from 11.9 to 13.2? 3.7L SUV here. It alternator works great. Still runs after starting up as showing 14.3 voltage. just don't want the voltage to drops to dead state due to long term parking.

13.2 should not really be seen with the car off, more like 12.8 with a strong battery. This should help, keep it in a better state between charges

Even the Noco 1 helps but slower.

I also noticed pulsetech mainteners are also on sale similar price. Wonder if they are better or practically the same. Pulsetech was used on military products

Just to reiterate, the Genius1 is cheaper (currently $24) and works great for maintaining a seldom used vehicle battery.

Make sense. I was going to getThis one however I learned that this needs to plug into the wall to work so no go for me.Honesty I was hoping for something like this but without plugging to the wall in order to charge the car battery. I use street parking as a matter of fact.

Why is this Noco better than the Schumacher with a 15amp rapid charge for $34?

Was looking at the Genius2 for a car that hardly gets driven. Any reason to get the 5 over the 2?

The higher models charge faster (2A, 3A, 5A, etc.). Even the the Genius1 charging at 1A should top up a slightly drained (20%) 50Ah battery in 10 hours. So half that time with the Genius2.
