You know the warning you get to shut off the vehicle if you've been sitting with the radio on but the truck isn't running? I'm getting that as soon as I shut the engine down and put it into accessory mode. Does this mean the battery is on its way out? Or could it be something else? As far as I know, I don't have any drains on the battery and it never has a weak start after sitting.

 

How old is the battery?

 

Get it tested.

 

the battery testing seems kind of hit or miss honestly but if the battery is 3 years old or so it's definitely suspect. I would also verify the alternator is charging properly just to be sure

 

Without looking, I bought the truck three years ago next month, so it's at least that old. Yeah, I'll get it checked out.

Thanks!

 

my vote is getting a new battery. within our household, 5 vehicles, 4-5 years seems to be the norm on batteries nowadays, at best.. seems like every few months another vehicle needs one.

 

you're lucky, most batteries these days are good for 2-3 years max.

 

3 years, dont waste any time testing! IMO, just get a new one!

 

That better not be true. My OE lasted around 7 before it started showing some issues. Just passed 3 years on a nice AGM.

Testers are inexpensive. I've used mine on several cars to assist this decision.

 

You are about to go into freezing winter time, just go buy a decent battery.
