    Works so well this is my second one.
    Works great for all my batteries. I like the percentage feature that lets you know the battery percentage charged. I was able to diagnose a battery that needed water added to it since it would not fully charge. After I added the distilled water the battery fully charged. Works great this is my second one. The other one still works I just use it as a battery maintainer on my truck. I have battery tenders and nocos this is the best one for the money. Quick charge and it shows the percentage charged on the display.

      I had replaced my battery on my Mazda 3S three times (under warranty.) My mechanic advised that I needed to drive more as under 5000 miles over a two year period wasn't going to keep the alternator going enough to keep the battery sound, and the battery folks weren't going to replace it again.

      So. I bought this charger, and watched the videos supplied here on Amazon. It was stupidly easy to use, and it just works. Now I don't have to worry about my car not starting because I haven't gone anywhere in a week or two. Or more (to be honest).

      Great product for a non-mechanical person like me. And it gives me peace of mind.

      Purchased this over a month ago. Have used it off and on in that time to keep motorcycle and other AGM batteries topped off for the season. This puts a top charge on (as expected) in a fraction of the time of my trickle chargers. It's so much easier than pulling out the big charger. The unit has a nice design and the hanging hook is very handy although it feels flimsy, it works fine. Like the digital display. There is no visual charge level status except at the very beginning to tell you the initial charge level in the battery. It would be nice to gauge how much longer the charge may take when checking on it. Not a deal breaker by any means. It does what it's suppose to; charges batteries well.
      Comes with many connection options in the box. All are great quality. This has become my #1 charger.

      Update after a year of ownership: This charger has an ongoing issue charging AGM batteries. Will only charge partially. Green light fading indicating full charge when Batt is only at 83%. Also has aborted charge for no reason on newer AGM. Have to unplug and restart to continue to get a full charge. Happens the same each time. Average use is once a week during the colder weather. It became nuisance having to check on it all the time because it has no state of charge indicator. Learned to work around the quirks for now. The scrolling marquis display is nice but seems more of a novelty. Having 4 batteries (2 AGM and 2 MC batts) to maintain, it can become time consuming waiting for it to cycle each time Except for these issues, it still works and gets the job done.

      In the World of Charger Maintainer's this is the Cat's Meow. I wanted a 3amp charger so I could use it on the Lawn Mower as well as the Truck and Tractor Battery. Also I didn't need a 6V Charger so I chose this one because it can charge lead Acid Flooded, AGM, Gel, and 12V Lithium Ion Batterie's. This Charger Show's the Current Batterie's State of Charge in %, and then proceed's to charge it, while showing in Real Time the % of Batterie's State of Charge! When the Battery is at 100%, the Charger will stop chargeing and Automatically go to Auto Maintain and Display that message. I use this on my 650cca AGM Truck Battery, 840cca Lead Acid Tractor Battery, & 250cca AGM Lawn Tractor Battery. Schumacher Customer Tech's will tell you that it can't be used on Large Batterie's but they don't know their Product's. I guess they don't know much about their Battery Charger's because they don't use them; the Charger's are Made in China, and I'm guessing the Engineer's that make their charger's are Chinese as well, and probly cause the Chinese now Own Schumacher and are just letting the American Customer Service keep their job's as a Good Will gesture. The woman answering the phone didn't even know how to navigate their own Website! The Tech's said that this charger wouldn't charge my 840cca or 640cca batterie's. I've been useing their 1.5Amp charger maintainer's on my 650cca, 840cca, and 250cca Batterie's for over 20 year's, so I knew that the 3Amp charger would charge fine and now I have one that will display the Batterie's State of Charge. This Charger Maintainer is the Best that I know of. The Slower that a Battery is Charged the Better it is for the Life of the Battery
      ***UPDATE 2/7/23***
      My old 3A SP1297 is still functioning good. According to the Senior Tech @ Schumacher the New 3A SP1297 DOES NOT HAVE THE DESULFATEING MODE now. Also the 6A SP1298 DOES NOT HAVE THE DESULFATEING MODE. Just for added information in case you wanted a charger that has the ability to desulfate a battery. However according to the Senior Tech @ Schumacher the 3A SP1356 DOES HAVE THE ABILITY TO DESULFATE A BATTERY.
      ***UPDATE 1/3/24***
      Led Display was starting to miss part of the Display so I decided to get a New one after 3 year's. Stumbled upon the FRO1542 4A Farm and Ranch Charger/Maintainer. According to the FRO 1542 User Manual @ SchumacherElectric.com (Farm and Ranch Charger FRO1542),,,
      It does everything that the SP1297 will do and a Lot More includeing Charging and Maintaining Small Lawn Mower Batterie's as well as Larger Batterie's UP TO 1000 CCA'S!!! AND IT IS ONLY 20 $'S ON AMAZON!!! Ordered 2 and seem's to work better on my 800 cca battery than the SP1297!!! I just ordered 2 More before they discontinue them. Schumacher doesn't seem to know much about them or Believe the User Manual ~ GO Figure. Schumacher seem's to only recommend a much more expensive charger. For 20 $'s these FRO1542 Charger's Should be Flying off the Shelf's. Don't be a Day Late and A Dollar Short, Get'm While They Are Available..

      I found this unit self protected and easy to use. You just have to pick between a lead acid or lithium battery and it analyzes it, tells you how much the battery has discharged and takes over from there charging and maintaining your battery at a slow amperage rate.

      WARNING! - product worked OK but failed just after warranty expiration. Called customer service, and service rep provided RMA link for free replacement. Followed lengthy process to submit the replacement request and was immediately denied. Now Customer Service will not reply to inquiries.
      DON'T WASTE YOUR MONEY AND TIME!!

      This is my 3rd unit. I use them on 3 vehicles in storage, on Winnebago, BMW Z4, bmw 128i. So easy to set up and the digital display is what I like. No guessing. Display gives status.
