No sirvio no hizo nada
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

Very nice charger
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.

Very good, small easy to use battery charger.
Small computer control. Flexible battery charger. I like the unit very much as it is easy to do. Just plug in snap-on to the battery and let it do its thing and it'll slow down when it's charged the battery automatically.
