My 2014 RRS turned 9 years old last month. I was curious to see how long I could get the original battery to last. Sort of a game. When not in use, I had the Sport on a Ctek battery maintainer. Yesterday, 3 miles from home, the radio went blank and the dash lit up like a Christmas tree. Pretty much all systems from the gearbox to the ABS to traction control and more had faults. Also my radar detector was going wild for some reason. I made it to my driveway and started to turn in and the car died and wouldn't start up. Using my jumper box, the car started and I pulled into the garage. I'll be changing the battery this weekend. Moral of the story is change your battery before 9 years. RIP

It would be prudent to also check your alternator output once you've fitted the new battery.

Great job getting the most out of your battery. I, too, keep mine hooked up to my CTEK. Hopefully, I’ll get even close to as long as you did!

I just recently changed my battery after finding out it was the original from 2014. I had no issues besides start/stop not working. Did the math, and the battery was still going strong after 7 years, 8 months.
