We have an 07 Prius with 101,000 miles on it and from what I've read it's about time to have to replace the 12v. starter battery. Again, from what I've read these batteries typically last four to five years. When we first bought the Prius in March I checked into these 12v starter batteries at my local dealer and they were about $135 (about what others I've read have paid). So, after saving up the money to get a new battery and a few other tune up parts, my dealership now tells me that the price for the battery is $260!! Just curious to know what others have paid for this 12v starter battery recently? My dealership assured me that they don't price gouge and all the other parts I bought were what I expected (thanks to PriusChat). Needless to say, I told the parts guy that I wanted to check into this 100% price increase with my friends at PriusChat. Thanks!
