After the battery had just been fully charged I put the Enusic / Foxsur charger into Pulse Repair mode. The "Rep." indicator appears at the bottom of the LED display and is not flashing. The entire progress graphic flashes. The charger will continue in this mode until the battery if fully repaired. This could be minutes, hours or days depending on the condition of the battery. I wish the charger would display the internal resistance of the battery during the repair mode. It would be great to watch the progress!

There is a very good review on YouTube from "Phil UK Net". He used a Foxsur pulse repair charger to repair his car battery that has sulfation. It is definitely worth watching. He shows you the before and after results using a battery tester...
