I have a 2010 Civic I bought new.
I needed a jump start twice yesterday so the car is in the shop ( independent, gas station ).
I thought it would be something like the alternator, but the mechanic just called me and told me those systems were fine. The batter is corroded and near dead.
He said about 4 - 5 years of life is normal for a car battery.
I can't remember changing my battery that often with my old car ( 1991 Civic ).
Is the mechanic right about the life span of car batteries?
