    Had previously bought cheap versions of these and they did not last and I believe fried a couple batteries! Not worth saving 20.00 on a charger and then having it destroy a 300.00 battery!

    I had a Noco battery product years ago. Not impressive. The company seems to have picked up its game. This thing is simple, and seems reliable, at a good price point. NOTE: I do not trust "leave it on charge all winter and it will work automatically". Not for ANY of these chargers. I charge my batteries up. Then uncouple the tender, then recharge in a few weeks. This avoids having to trust little micro circuits somewhere in a black box - that may of may not work flawlessly month after month without checking.

    I recently purchased the GENIUS2 and I must say, it has completely exceeded my expectations. Right out of the box, the first thing that struck me was its compact design. It's small and lightweight, making it incredibly convenient for storage and handling.

    Setting it up was a breeze. The instructions were clear and straightforward, ensuring a hassle-free experience even for someone who isn't particularly tech-savvy. This ease of setup is a huge plus, especially in emergency situations where time and simplicity are of the essence. Simply connect your battery and turn the device on, click the button to select the correct mode and you're good to go!

    The fact that it works as expected without any complications adds a level of trust and reliability that I greatly appreciate.

    Additionally, the packaging was well-thought-out and secure, protecting the charger during shipping. This attention to detail extends to the charger itself, which has a premium feel to it. The build quality is excellent – it doesn’t feel flimsy or cheap, which is often a concern with tech products.

    Overall, the NOCO GENIUS2 is an outstanding product that I would highly recommend. Its combination of compact size, ease of use, efficient performance, and premium build quality makes it a top-notch choice for anyone in need of a reliable car battery charger.

    I would go through the problem of not having to use my car for long periods of time which would ultimately drain my battery. I would suffer through by using a portable jumper, but the problematic battery would persist. I started investigating in alternatives like unplugging the battery from the car while it is not in use, but I would still have to get a new battery regardless. I luckily stumbled into this product that changed the game entirely.

    My battery was absolutely drained and would not even crank the starter motor. I got this product and set it up using the instructions and it charged up right away. It was very practical to use with ease. All that is needed is to latch on to the terminals in the appropriate order, plug it in, and in the push of a button it revives the battery. I was able to recharge my battery back to 100% over time and it starts without a hitch. I would just leave my battery connected to this product and check up on it every once in a while. Very simple, very effective. Highly recommended.

    5.0 out of 5 stars Excelente cargador muy versátil
    Reviewed in Mexico on February 10, 2021
    Verified Purchase
    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.
