HI, I have just bought my first hybrid. It's a 2017 Fusion Hybrid Titanium and I have had it for about 1 week. I have driven it on the highway, and around town. It seems like no matter what I do, the battery charge indicator only peaks at 50% full. I have driven about 100 miles so far probably 50/50 highway and city. I'm averaging 43 MPG which is great. It seems to charge well when I stop and coast. My Questions: Since I just bought the car (used - it was a rental car before). 1) Should I make sure it will fully charge the battery? How do I fully charge it? 2) Should I expect the gauge to hover around 40%-50% at all times? Thanks for the help. I'm a hybrid newbie! BL
