Well for a few weeks now my CTek battery tender would keep showing the red light when trying to charge the battery on Scarlett. I thought maybe it was just the charger being bad but sure enough, the battery was down to 10V and was not holding charge. Very strange since it was only about 3 years old and I haven't put that many miles on the car. Either way, replaced it with a new battery and all is fine again.
Maintenance Update:
Mileage: 173,372
- New Duralast Platinum H6 / Group 48 AGM battery
