2WD technical question
Hi folks,
Went to pick up a friend from the airport last night. It was quite cold (5c) and my Mazda 323 really struggled to start. It did eventually, but was very reluctant. It was about a week ago that I last drove it. Once running it was fine and when I started it again at the airport to come back to the flat it started no worries.
I'm thinking it seems like a crook battery (it is pretty old I think, and I drained it completely flat once by leaving an interior light on).
When I tested the battery this morning it was reading 12.57 Volts across the terminals with engine off and no load on. Does this seem low? Of course, it got a charge on the drive to the airport last night, so I'll test it again tomorrow to see if the charge has dropped further.
What Voltage would you expect across the terminals in a healthy car battery?
Cheers,
Matt
