> it refuses to run the alternator on any road slower than 35 MpH I noticed this in my 2017 Subaru Outback when I went to jump my wife's car. The car was running, but the battery voltage was only sitting at 12.6v or so. I'm used to a battery putting out 14v or so when the vehicle is running. The extra voltage seems to help a lot when jumping another vehicle. I understand why they did it, but it seems odd. Perhaps it's why my battery died after 3 years, when most others I've had last close to 5.
