The start/stop hasn't been working as often as it used to and it always says "battery charging". Now i had assumed this was just normal, but now i have this current issue that may back up that either the alternator has been low on output for a while or that the battery isnt great. Or both i suppose. Its never failed to start.

The Alternator has basic charging regulation built in but modified by the car to suit conditions .. it does seem the alternator is weak or non existent , the water probably finished it off.
