Hi - I’ve got a Husky QC500 battery charger used with 2x Husky 300 batteries. It is 14 months old, and has done 7 or 8 charges max. It’s kept indoors on a workbench, plugged in to normal mains supply when in use. It has now stopped working - I swapped the fuse but that’s not brought it back to life. I’m sure I’ve heard other people mention issues with these chargers - does anyone have experience of them failing at all? Cheers, Dan
