After servicing my 2019 Prius, the Toyota dealer said the 4 1/2 year old 12V auxiliary battery needs replacement, quoting $336 for replacement. They tested the battery at actual CCA 230 vs. 295 Factory CCA. I’ve not noticed any problems and the vehicle only has 14,800 miles, but I don’t drive every day and mostly drive short distances in the city, which may be a factor contributing to battery deterioration. Another reliable auto shop I’ve used in the past quoted me $275 for installing an Interstate MTX battery with a 3 year warranty. My question: Is a dealer-installed Toyota battery preferable to an after market brand? I’ve read that all auto batteries in the US are manufactured by a few companies and rebranded for different outlets. But Toyota implies their batteries are specially designed for their vehicles. I’m a novice at all things vehicle-related and would appreciate any advice from the experts on this site.
