    Hay mucho que considerar al cargar una batería de auto, éste cargador es ideal para varios escenarios. Lo compré pues muchos autos nuevos con baterías AGM no deben ser cargados con un cargador que no diga expresamente ser para AGM, de otra forma puede acortar su vida.Este cargador puede usarse con baterías regulares de plomo-acido, AGM, litio y hasta de 6V. Tiene indicadores para polaridad invertida, batería dañada, además de nivel de carga en 4 niveles. En ésta versión de 2 amperes (Noco Genius 2) una batería que marque el primer nivel puede tomar mas de un día en cargar, pero lo hará extendiendo lo mas posible la vida de la misma.Para autos que no se utilizan mucho, es indispensable un cargador como éste, de lo contrario la batería se puede dañar por la falta de carga, así se arranque el motor cada mes, pues no es suficiente, particularmente para las de plomo-acido. Incluso autos que solo se usan para trayectos cortos dos o tres veces por semana, la carga que obtienen no es suficiente y terminan descargandose y dañandose si no se hace algo al respecto.Por el tipo de carga que generan éstos cargadores, se pueden recuperar hasta cierto punto baterías que ya fueron indebidamente descargadas mas allá de lo recomendado. Las AGM son las que pueden resistir mas, una de plomo tal vez no se recupere al 100% pero se puede extender un poco su vida. El hecho de que cargue lentamente es precisamente para extender la vida de las baterías y mantener cargadas las que no se usan. Si requieres un arrancador o una carga rápida, ésto no es el producto que necesitas. Las cargas rápidas terminan disminuyendo la vida útil de cualquier batería.Es un producto excelente para museos y colecciones de autos, garantizando que autos sin mucho uso estén siempre listos y que las baterías no pierdan su vida útil. Se puede comprar el accesorio para conectar permanentemente a la batería y dejar el conector tapado pero accesible para rotar el mismo cargador entre varios autos, dejandolo un par de días en cada auto.Yo lo compré para un auto que casi no uso y como tiene batería AGM, no podía usar mi cargador/mantenedor viejo. Lo recomiendo bastante, luego de una carga se puede desconectar y permanecer meses sin usar y arranca a la primera, aunque lo ideal es dejarlo siempre conectado si es posible. Cuando ya está cargada, se mantiene en modo de espera.

    Great product, I had a car that was parked for 4 months and the battery died. It was a bit slow. However, it charged the car battery within 48 hours

    Had one for my motorcycle for a LiFePO4 battery and worked great vs Motomaster 3A that eats batteries. Bought another one for the boat’s Deep Cycle as again had issues with the Motomaster one and paid way less on Amazon than I did the other one. I can leave it on the battery even when it’s not charging, and it doesn’t draw amps. The Motomaster one would drain the amps preventing it to crank if I left it on. Will probably buy 2 more in a near future for the other toys.

    Awesome – very pleased
    Packaging is awesome, just like an Apple product! Device is simple and works very well. Practiced on a 25 HP lawn tractor first, cycled through it all them went to maintenance mode. Then on the high end car that’s no driven ofter, same results. Only dislike, instructions are small, hard to read. Suggest YouTube to understand the icons on the charger. Great price, feel confident.UPDATE: NOCO support User manual is now online and is good, received a reply after complaining.

    Does not work as a “maintainer” – UPDATED – figured out how to make it work as maintainer on string
    Updated review from 3 stars to 5 stars. I experimented and connected the terminals to the inverter terminals and it now goes into maintenance mode. Something about being connected to a single battery in the strings causes it to give an error code and shut off. It does not do that when it is connected at the furthest terminal from my battery string, which is the inverter terminals. It works great now. I was so happy I bought the 10 amp version and loaded up the inverter with more devices to test it out. It works great. So now, even when my power goes out, I’ll still have my wifi dish, security cams active.I purchased this charger/maintainer to leave connected to (2) 35AH AGM batteries (parallel) and it works great as a charger. I have an inverter connected to these batteries and I wanted to run my security cams and Wi-Fi off batteries while being maintained by this unit in case of power failure. Didn’t work out as planned. It will charge the batteries, but every time they reach the cycle to full charge, the next day I get battery failure and the unit quits charging. Once I unplug the charger from AC and plug it back in, the unit again charges the batteries to full charge, next day battery failure light. The batteries are only a year old and have little use on them. They hold a charge well. So now I have another battery charger. It’s a nice little trickle charger, but not a maintainer on my batteries.

    Works great n easy to use
    My wife has a 2020 Honda Civic tour and sometimes it might sit for two weeks before she drives it. With all the electronics in these new cars her car battery will be dead. I have had this charger for couple of weeks and keep it hooked up. Works great! This also keeps the battery charged and healthy.

    Compact and charges well
    I use this on my UTV, motorcycle, and lawnmower. Works great and I love the small foot print. The one thing I would change is to make the clips smaller so it can fit on the battery post better. I had to remove the cables on my motorcycle to use this.

    5 years still going strong
    5 year long term reviewgoing through my archived orders i came across thisbought this charger 5 years ago to use as a trickle charger for my camper batteries, it has been hooked up to those batteries constantly except for the weekends we are out camping, meaning it has seen almost 100% usage since i purchased it and it still works like a charmmy camper is stored outside so the charger sees 100 degree temps in the summer and -20 in the winter and has performed great in every conditionvery happy with this charger and would buy again anytime, great value for the money

    Great Charger
    I am thoroughly impressed with this little powerhouse! I needed something to charge up the battery on my generator and this worked flawlessly.This is a high quality charger with easy mode switching and super simple to use. I was worried that I did not get one with enough amperage, but this charged up my generator battery enough to power it on after about an hour.I have not yet needed to hook it up to a larger battery such as a car, but for a generator battery or something similar, this charger easily handles the task and isn’t overly expensive for what you’re getting.

    Works well
    Works well to charge flooded, AGM and lithium batteries. Topped off my AGM battery. Highly recommend buying the NoCo GC003 cigarette lighter adapter. Just make sure you connect to a 12v socket that is always on. Strangely does not ship with instructions or manual. Had to look it up online. Same day shipping from Amazon- can’t be beat.

    Just what you need for cars that aren’t driven often.
    I got this for a special Mustang that is not a daily driver. I was disappointed when I found the battery was dead. I was going to just replace the battery but decided to give this a try. Super simple, and after a full night, the battery was charged and good to go. I have since put it back on periodically and it keeps the battery charged and ready to go.
