I’m also getting the ‘electrical system drain’ warning on a daily basis. There is nothing plugged into the car, but I do have the ChargeSmartMA app that allows the electric company to throttle my charging if they need extra juice.
I’m thinking I should desulfate the battery to be sure that isn’t part of the problem. I have a CTEK MUS4.3 polar charger. In all the charging programs it starts with a 15.8 V desulfation cycle for up to 8h. @Mach-Lee I assume this charger is not appropriate due to the high voltage and I should get a charger specifically for AGM batteries?
