Way ahead of you. Already called Ford, they don't have the battery I want in stock but the dealer in Lindsay does, so it'll be getting the 850CCA battery tomorrow.

Yes, both tests were after it had been running for a while. The 2nd test, it had been running longer.


The more expensive Midtronics conductive testers do temp compensate. But not the affordable ones like the PBT series. Possibly the difference in the two tests could be explained by one temp compensated and one not. If indeed that is the case.

So did you get your new battery OVERKILL? How's it starting?
 
Ended up not making it there yesterday, but my wife just called me and she's picked it up now. I'll be putting it in when I get home. Truck almost didn't start this AM, so that appeared to be the motivator to go get it, LOL!! Because she was unwilling to do so yesterday

Fear of having to walk can apparently be an incredible motivator, LOL!

I'm disappointed in you overkill only a 30% overkill battery

(850cca vs 650 stock)

I thought you would end up with something more overkill...

a Braille i65D


all joking aside I'm sure the motorcraft will provide good value and service.

I had to take the truck out this evening, BIG difference in how it spins over with the new battery. Amazing how you don't notice that very gradual decline in how fast the engine turns over but when you have a new battery in there, then it becomes readily apparent!

OK, first cold start with the new battery this AM. Started like it was the middle of summer. Motorcraft 850CCA battery for the win!

Indeed! It was -20C, so plenty cold and below where the other battery was doing the grunts. Lesson learned on this one. I expect the Motorcraft to last a long longer than the Exide did.

..my daughters 2002 lincoln had the battery replaced 5 yrs ago with an aftermarket battery ( according to the auto tech guy, the original batt wasn't up to lincoln standards ) ...that same unit was then installed in her van which is still being used to this day…interestingly, the aftermarket batt from 5 yrs ago was just replaced..this time we went back to OEM and were she lives it gets very cold.. hopefully it will outlast the car..

Yep..+1. I'd add TEMPERTURE to the three above. If your starter/solenoid is going Toes UP, it'll draw more current over time, which you'll have less of as °C drops..particulary in the GWN. As you live in a COMPLETELY different environment than I do, you need a battery that does well in your temps, not mine. I remember Volvohead liked Deka batteries, he lived in CT?, NH?. Much colder than here.
 
If the battery is more than couple of years old, I just replace it even without bothering to get my multimeter out (just a slight exaggeration) on the first sign of electrical trouble. I don't seriously start doing diagnostic until the battery is replaced first.

Many of the newer cars and trucks we have here can exhibit bizarre symptoms that eventually trace back to the battery. We also don't mess around, as a tow for our service trucks is as expensive as the best battery...
