What has been others experience with NAPA electrical parts. For me it hasn't been so great. I've replaced three batteries and alternators in the past three years. They seem to last 1.5 years and then bite the dust. I got a NAPA Legend battery which is suppose to be a good battery. The first one lasted 6 months, the next 1.5 years and the replacement battery now has lower CCA than the original that I purchased and cost more. The alternator goes bad out of sync with the battery. I got a replacement alternator today, but not from NAPA. I got one from Autozone with the life time warranty. It seems to be of better quality and warranty than the NAPA alternator. Time will tell. I really have never had a bad experience with Autozone parts though. Ironically my replacement starter from NAPA, 1 year warranty, and the cheapest one has lasted for 60k and has never given me a problem.
