My car battery is running a 15.5 volts all the time yet at times has a slight struggle to start. It's been really cold lately in the teens and colder. Is my battery bad? Car was put in service in June of 2011 so it's almost 8 years old now.

    15.5V is not possible with a normal car battery - unless that is being measured while the engine is running which then says little about the battery itself. – mike65535 Jan 28 at 13:48

Any lead storage battery over five years old is suspect. In my 30 years' experience, waiting until eight years to replace the battery always leads to trouble.
