### ⭐⭐⭐⭐ Review
*by D***S on 5 April 2025*

I ordered this charger because it has a "repair" mode for batteries that have sat for a while in a discharged state. I have a deep cycle marine battery that was flat and hoped the repair mode would work. Regrettably, it did not. No way to tell if the repair mode is a gimmick or if the battery was just too far gone. The charger has several other modes and, while it's a bit fiddly to use, consulting the instructions is key. Best to keep them handy.
