P0625 & Battery light came on

Got the code a week ago, cleared it then it came back on today. Battery voltage while idling ranges from 12.8 - 13.3 volts, and driving under a load it's 13.8 -14 volts. No lose connections or corrosion on connections.

Is my alternator on its way out? Or are the batteries about to crap out?

No they came on the truck, and normally the date is on the battery somewhere but nothing visable but they look fairly new, had the truck about a year.

Ok, damgit. I know I can search and read countless threads- but what's a good replacement battery? I have a buddy who works for Interstate Batteries so I can get my hands on just about any brand and type.

Likely batteries, Check you voltage with engine not running. You are reading alternator voltage with the engine running.

Engine off battery voltage should be over 12V. If you read less disconnect the ground on the drivers side battery and check voltage on each battery separately. in several cases I've seen one battery read low between 7-10v and the other battery read good 12V.

Also you can take your truck to a Wallmart service Center and they will check each battery and give you a print out showing condition of each battery. Takes about 5 minutes, they disconnect ground at each battery. They don't charge for test even if you don't buy there.

Ok I checked the batteries today with my volt meter with neg and pos leads disconnected- 12.74 volts both batteries. I scuffed up the battery terminals and the connections. The light hasn't came back on yet.

On a good note my buddy at interstate can hook me up with new batteries for $80 for 2 new batteries! So I'm gunna get the new batteries anyway just because the price is insane and I don't know the age of my current batteries.

I had one bad battery kill my truck. The other one was good, but the bad one was sucking the life out of the good one.

I've had them over two years now. They have been great. Truck sits for up to a month at a time in the winter and it always fires right up. I run optimas in all my vehicles average about 7 years out of them.

I order them online from advanced auto and get 20% off for just buying online (and sometimes get a $50 gift card) and then pick them up in the store. It saves quite a bit.
