That sounds unfortunately like it is an issue with your hybrid battery rather than your 12v car battery - based on your figures from the battery and alternator

Hybrid battery is charging just as it use to, it's always charge up to 12 miles that all it ever got , if it's the hybrid battery that sound expensive

Test the 12V battery in the morning before starting the car, see what’s it’s like then. <12.4 volts and it needs a charge/replacement
