Cleaned a lot of corrosion off the negative battery terminal on my van, and in just a few weeks it's back again. Supposedly a 'sealed' battery, but I assume it's cracked and leaking which is what causes the corrosion to form?
No. Corrosion (usually white) on the negative terminal indicates low charging.
If this is when running, the alternator is delivering to the battery, time to test the battery as it probably isn’t holding. At least that’s what I believe.Volt meter (after market) reads 14.1v almost all the time. So the battery isn't taking a charge, or the charging system is suspect?
The battery at rest with no load should be around 13V.Volt meter (after market) reads 14.1v almost all the time. So the battery isn't taking a charge, or the charging system is suspect?

The battery at rest with no load should be around 13V.
With the engine running, it should be around 14-15V.
Sounds a little low.At rest no load after driving ~80 miles today and sitting for 3 hours after.... shows it at 12.15 V
That's way too low for a battery that should be at full charge.At rest no load after driving ~80 miles today and sitting for 3 hours after.... shows it at 12.15 V
That's way too low for a battery that should be at full charge.
The Ford factory batteries are not high quality.Yep, costco run tomorrow to swap it out. I have no idea if it's the original 2013 or not, I've only had the van for 1.5 years. It's an actual "ford" battery though, I can't imagine anyone buys those except when it's new... right?
I ran the original factory ford batteries from 2011 f250 in my truck till sept 18.The Ford factory batteries are not high quality.

Wow! I've driven new company vehicle Fords that get replaced every four years and the batteries sometimes make it two.I ran the original factory ford batteries from 2011 f250 in my truck till sept 18.
So it is possible its factory
I was actually told yesterday by an Interstate battery guy. That corrosion comes from slightly overcharging
True, over charging leads to the acid expanding and act like it's boiling. That would tend to be a whole lot of acid, everywhere. The most common is leakage if it's located in a specific area.
