I understand lots of cars will be different. But what generally is the default mode in cars with smart charging if the battery sensor is disconnected?
Context...
My Duster leaves the battery in varying states of charge. When you start up the car it will charge at 14.8v for a period of time that could be 10 minutes or 30 minutes. Then once (I assume) it detects the battery is of a satisfactory charge level it will drop down to 12.8v. Then whenever you coast it will ramp up to 14.8v again until you get back on the throttle and it'll modulate back down to 12.8v again.
When the engine is turned off the battery can settle anywhere from 12.8v to 12.1v. If the car is turned off with the battery sat at 12.1v and left for a few days this can easily drop down below 12v.
I must add that the car has never failed to start, even when the battery has been down at 11.6v, it's warmed the glowplugs up and started without a fuss.
I just dislike having the battery at such low states of charge.
I put a Noco Genius 1 on it Friday night as it was reading 12.2v after the engine had been shut down and it took from 7pm Friday night to 4pm yesterday (Monday) afternoon before the charger went into 'maintenance' mode (i.e. the battery was 'full).
I'm wondering if disconnecting the sensor is likely to disable the smart charge system and maintain a constant ~14.5v or so and maintain the AGM battery at a higher state of charge? Ideally without triggering any warning lights or errors.
