I have a 2015 Honda Civic and I got a new battery for it about six months ago. Recently the car hasn't been starting and required jumps every morning to run. I took it to the dealership and they let me know that the battery and alternator were both fine, but I'm not driving the car enough and the battery voltage is dropping below the minimum needed to start. They recommended that I drive the car more.
I'm privileged enough to be in a position where my work is only 2 miles away, so I only drive about 5 miles a day on average (maybe 35 miles a week). My question is, what's the minimum I should be driving per week to keep my battery in good condition and properly charged? Does it matter how fast I drive (should I take my car on highway joyrides every weekend?) to keep the battery charged?
Are there any other solutions to this problem? Thanks!
