We live in the country so good tires, full tank of gas and strong battery are essential. How do you keep your battery charged? On my trucks I put the charger on them periodically, charge at 10 amps for a few hours to get them back to full charge. They do not have the amount of electronics as the MKC so I did not want to make a mistake in case the charging protocol was different. I do have a whole house surge suppressor in my main electrical panel so that should take care of surges/spikes.
