This charger is even better than the expensive ones (noco g chargers). This charger does everything automatically, you don't have to do anything, just plug and play ๐, it adjusts volts, amps according to the needs of the battery. I used it on my lithium battery and it brought it back to life from 0% to 100% and also did some maintenance. By the way, this charger is underestimated, it puts out more than 7.3A.
