Many of you may know this already, but I found out some batteries aren't compatible with memory saving devices. I.E. a programmer. My battery would die every time I would back out of the garage and then turn the truck off to wash it, cut grass, etc... I also went on vacation for 10 days and when I came back it was dead. Well after getting the battery tested twice and it passing, and then failing emissions I figured I would just bite the bullet and buy a new battery. Well glad I did my research online first because using the vehicle function on several auto sites to find the correct battery I began seeing disclaimers about "not intended for use with memory device." anyways, to those may have this issue I've just been unplugging my Edge unless I know I'll be driving for an extended period of time.

 

The edge has a memory ?? after you program a level...you can unplug it !! It don't have to stay plugged in...

 

That's what I am referring too. If you leave it plugged it then Edge stores the AVG MPG, color, brightness, etc... That can slowly drain the battery.

 

It may slowly drain a weak or bad battery...I doubt it would drain a good batt.

 

very strange... i had left my truck unused for a month once, and I did not had a problem with the evo edge installed there. i never remove it.
also, the radio stores your music stations and stuff, so... at the bare minimum you have a radio with a memory for your fm selection.
why somebody will make a car battery that does not support even a car radio with memory?

 

He must of had a weak or bad Batt.

 

While I'm not disagreeing with y'all, I'm just saying that in the last 6 months I've seen an issue with mine and I saw where it was a battery not recommended for memory saving devices.

 

I had the same problem if I left the truck sit for a couple weeks. No problem now with the SCT livewire. I guess it doesn't pull as much as the evo.

 

In the 25k+ miles and year and a half Ive had my Edge Evolution its never drained my 6+ year old 108k mile original battery.

 

This also may relate to when Ford began using the smaller battery too, I know when looking up batteries my 07 OEM issued is a 58 550 CCA, while 04-06 are 65 750-850 CCA. Regardless I must have a battery that has seen better days. I'm going to go with an AutoCraft Silver 58 550 CCA since I see mild winters here in GA, but it does have a 2 year warranty, and a 5 year prorate. I might be the exception and the guys at Advanced Auto Parts say the battery is good, but whatever...i'm tired of jumping it off. I've done it about 1/2 dozen times now since I installed the programmer in December 2011.
