Ticopowell has given you the straight scoop here, except for one TINY detail.

My truck, since it's a bit of a "Garage Queen" like 88Racing's, sits with a "Battery Tender" plugged in at all times when I'm home. I've posted in many places about the "parasitic" draw on the battery from all the OEM electronics and the things I've added to it. If it is not driven for 3 weeks, the battery would be dead. The Battery Tender, which is not a "boil your battery charger", keeps the battery at a full charge state.

I do not disconnect the Battery Tender when I change the tune. If you DO connect a charger, make sure it's one with a 2 Amp setting. I don't know that a higher charge rate would hurt anything, but it might (and I would not risk it).

Here's a link to a post I made in another forum that will answer your concerns. Please read it carefully: http://www.f150online.com/forums/chi...unes-read.html
