A great looking and functional battery charger thats compact and high quality build! Recommended!

No sirvio , la descripción dice que casi hace maravillas y seria tu cargador idel para jamas volver a comprar uno y mas por el precio, pues nunca cargo ninguna batería y dice poder revivir alguno, pues tenia una batería muerta y no pudo hacerle nada , ni cargar una batería de media vida , compre un cargador chino de esos de 300 pesos y cargo mi batería y ese si revivió la batería muerta jajajaja Que decepción de cargador por el precio le tenia muy altas expectativas, la calidad del producto si se siente premium robusto y elegante pero eso es lo menos importante, cuando quieres que algo funcione ni aunque este bañado en oro simplemente mala compra No funcionó con batería de ácido Ni tampoco con batería placa plana AGM

I have a car that I do not use very often and I use this charger to keep its battery charged. I am glad I got it instead of getting a new battery. In Arizona, because of heat, the car batteries stop functioning and we may have to replace the car batteries usually every two or three years. When my car did not start, instead of trying to get battery replaced, I decided to use this charger after watching YouTube videos about it. It worked perfectly and saved me some money. It has a very nice display.

As per title

As an electrical engineer I am very impressed with this product. Even its packaging is about the best I have ever seen. The materials and construction are very high quality. Its operation is straight forward and the large and bright display tells you exactly what it is doing. It was designed in the United States and is manufactured in China; the end result is a high quality and professional looking product. I purchased the Sigma 10 charger because it will properly charge multiple types of vehicle batteries, including the AGM battery used in my car. Newer vehicles with their highly complex electronic systems need the battery to be well charged, yet in the interest of higher MPG ratings, short trips will not recharge the battery fully. This charger has a permanent home in my vehicle so that when needed I can bring the battery up to full capacity. The Sigma 10 charger has a 3 year warranty, but that increases to 4 years if you register with Hulkman. The charger can serve as a 12 volt 10 amp power supply for other applications such as providing temporary power to your vehicles on-board computers to keep them happy while you replace the vehicle battery. The manual was not clear on how to select this mode, but Hulkman support responded quickly saying to Press & hold the "OK" button for 3 seconds to enter "12V Supply" mode.
