okay, so my 05 F150 that I got in may has died 4 times. I'm running an amp for the stereo- no subs., so if the truck is on it only lasts about 10 minutes before full drain, and I need a Jump. the other times have been with the radar detector plugged into the dash accessory outlet for 2 nights without driving the truck and need to jump the truck... is the battery that weak 650 cold crank., or have I blown a cell? when driving daily the truck will turn over immediately with no hesitation. what can be done? any advice?
thanks everyone,
Justin

 

First thing to do is disconnect all your extra equipment to see if the battery runs down in a day's time.
Normally a fully charged battery will last for months on standby without "running down".
You need to see if your extra equipment is the cause by how it's hooked up or even faulty, first.
Then depending on what happens , the charge system needs to be tested for drain by possibly a faulty alternator and/ or a bad battery if it still runs down with the extra equipment disconnected.

 

great, thanks for that list will get on it this week!
appreciate it-
