It is very possible that the alternator is overcharging. Did you check the voltage reading with engine running?
nothing yet, today is a holiday in Canada, will overcharging damage the battery or other electrical items in the car
It may damage the battery as well other electronic component if exposed for an extended period of time. Actually, the battery will become hot and explode...
Thank you for your help, I'll take it from there
When the battery started acting up, it was in the middle of a heavy rain, would the alternator be affected by water or high humidity?
Normally, the alternator should not be affected by that.
