My old sears Diehard Platinum battery was from 2009 and still working well but I could tell on my Racepak it was down some (going to upgrade my alternator too). I noticed Advance Auto bought the name so I’m going to give it a try (so far so good). With a 20% off coupon it was 170.00. Two events, 5 races and it working as I should. 3 year free replacement too.
