[QUOTE="Keshka, post: 1793878, member: 59199"] All most all vehicles the last 20 years have a certain amount of parasitic drain. It's what keeps the computers semi awake. Awake enough to listen to key fobs that might want to unlock a door as a minor example. The question would be how much is acceptable? Perhaps FordTechOne has the standby current draw on the Raptor. In addition, I would suspect a marked difference between models and year. The base line varies ...well alot! My ole '91 F150 can sit over six months and then fire right up. My 2010 MKT and my 2004 F150, each are good for about one to two weeks before the standby draw begins to cause starting issues. For those who think short hops don't add up. Here are the charging characteristics for your battery: [URL='https://batteryuniversity.com/article/bu-403-charging-lead-acid']lead acid charge curves[/URL] Read that....now what do you think? You will use around 8000 watt-seconds (joules) to start you Raptor on a warm sunny afternoon out of around 3000000 joules in your battery (theoretically). [/QUOTE]
