Review on 🔋 GOOAUTI Car Battery Charger Maintainer with Desulfator and Detection Function - 5 Amp 6V/12V Battery Charger for Motorcycle AGM Deep Cycle, Winter Mode, Portable 1 Amp Trickle Charger - Perfect Gift by David Herman

Battery #1: I bought this in a desperate attempt to get the best out of my car's ailing battery. I put the charger into repair mode to "repair" the battery. Left overnight, made some progress but no more than 40%. Instead I put it on charge mode and it started charging and was 100% charged within a few hours. This is a battery that has not been charged for almost a year. The battery was so-so at this point. In any case, I think I killed the battery by filling it with distilled water. Battery #2: I bought a new battery from Revain, looked at the manufacture date, it's a year old. I put it in repair mode. It showed that the battery is healthy. Put it in charge mode and show that it has been discharged. A full charge to 100% took about 2 hours. While you work like a champ!
