Re: OEM Battery Record?
I replaced my roadster battery in July 2014 (9 years, 3 mos and apprx 50k miles) even though it was still strong. I had had some leakage with the battery in my SRT6 and swapped it out with an AGM battery, then decided it was a good preventive measure against leakage in the roadster as well. I credit part of the long life to keeping them on a battery tender through the winter when they are stored.
