I will need one for my 70 Cutlass sometime soon but my Challenger's battery is now 7 years old. My last Walmart battery in a vehicle died just after the warranty period. I bought the car in 2018 with a big 850 CCA Napa battery with a big reserve capacity that was 2 months old. It is still going strong. The problem? The battery in my Dakota got drained about 3 years got drained and frozen. The Olds was sitting, so it is still in the Dakota. Are Napa batteries usually good? What are you guys experience with AGM or Optima batteries? The current battery in my Cutlass was replaced under warranty at a year old and is on borrowed time a couple of years later. Thoughts?
