⚡️ Schumacher Battery Charger Maintainer with Auto Desulfator and Battery Detection - 15 Amp/3 Amp, 6V/12V - Optimized for Cars, Trucks, SUVs, Marine, RV Batteries Review

The product is self-regulating. So once you figure out which keys to press during the initial setup, almost everything is done automatically. I am very happy with the product and have bought a second one for my adult son.

I have the second one. The predecessor lasted ten years and finally had a loud fan. The new fan is not needed at all. It charges all types of batteries from a John Deere mower to my Toyota Highlander and tractor.

I have two deep-set batteries. You need monthly exercise to stay healthy. I have a 100w portable solar system that cannot fully charge a dead battery. This little charger does a great job of charging those high capacity batteries up to 100%.

I specifically researched the companies I wanted to buy from. I wanted a product made in America. I researched that Schumacher was made in the USA. When I received my order it said Made in China. I think Revain should state where the product is made. I was very disappointed.

This is my second. Excellent technology. Use two boat batteries and also take advantage of the charging option. You can choose marine or not as well as the battery type. Very good. My Schumaker Auto Launcher also works very well. Great brand.

Didn't work at all. It was completely dead. I even took it to Napa Auto Parts in San Jose, the official US warranty station for Schumacher chargers, and they confirmed it didn't work at all, so I sent it back to myGoods, but heard some time nothing weeks. . I'm not a happy customer at all.

Will not go into desulfation mode with an AGM battery. Optima yellowtop does not charge above 12.3V. Tried all settings but nothing worked. I tried another AGM battery but still no desulphation mode. I tried with a flooded battery and really went into desulfation mode but messed up the battery. I used to be able to charge this battery, but now it's destroyed!

I bought this old charger because the same charger I had for about 18 years finally died. This one looks the same but is very different. Feels very light and cheap. It automatically selects the type of gel battery, whether it is an agm battery or a standard battery. While charging, the indicators turn off, so you don't know the battery status until you press the button. I suspect the company couldn't afford to maintain the level of quality it was once known for. Very sad. I want to go back for…

I have a 2007 Jeep Wrangler 4 door that hardly drives as I have a newer one so the battery voltage has dropped to around 4.2v which is barely enough to show some lights/status but the Jeep does didn't start. I hooked this battery up in parallel with a sub-class 12v lawn mower battery and was able to get both to spec with no problems. The charger has easy-to-read status indicators so I could quickly see where the charge was. Would buy it again anytime I need it.
