I recently purchased a 12 year old Honda Civic and took it in for preventive battery replacement. I was shocked when told battery was original equipment installed in Japan.
So much for the 3 year life mantra (which is true for Chrysler minivans).
I recently replaced the original battery on my Honda S2000, it was 10 years old. Not bad for an item that was garaged a fair percentage of the year.
Unfortunately, the OEM battery isn’t available in the States, it was imported with the car but not as a part.
I HAVE a 12 year old honda civic - just replace the original battery this past year.
