Blue corrosion on fast charger and two batteries
Charger and batteries are about three years old. Batteries are different sizes. Had a weird thing with the charger the other day where removing the battery didn't cause the displayed lights to turn off, even after unplugging it. Not really sure what to make of it. Humidity is fairly controlled where the charger and batteries live, batteries seem to charge and work fine on slow charger. I couldn't find anything similar for an ego charger, just plug in EV forums where people had much more significant blue corrosion.
