Again, how old is your battery? If it is more than 4-5 years old it is likely dying. You can continue to waste time on something that will leave you stranded, or you can replace it with a new battery. Batteries are consumable maintenance items on these cars.
Make sure the replacement is of like kind and rating and register it with the vehicle.

thank you, I will check the production date. it's a 2014 F10. car's production date was July 2013. the car started the services in Jan 2014. unless someone swapped my battery with an old one, I think it should still be in the okay status.
my car temp is 20F (-6C) . the production date is on the negative post ,right?
I will check when I get home..
Thank again!!
