Interesting article on battery testing
Alternators are there to run the vehicle, charging the battery is their second job. With all the electronic crap in vehicles these days it takes your alternator longer to get to its second job.
Most batteries will fail or come close to failing when you use a load tester on them since the battery is supposed to be fully charge before testing. Batteries were always easy money when I worked at the Gas station/Truck Stop twisting wrenches yeas ago just for that reason.
Like Tedster said, new batteries have a charge but it is not nowhere near full, I have a Genius charger for my deep cycle on my pool vacuum and it goes on batteries now and can give them a tune up, I put that on the Mustangs new battery and it was almost 8 hours before 100 percent and as much as my wife drives her Explorer I have been using the Genius on it over the big charger to maintain it. We also used to keep a set of Batteries at the truck shop charged, with 40 or so tractors running around someone was always needing a set and it was better to have a hot set to save time.
Edit; 2 hours later and it's fully charged. 80% was kind of disappointing seeing as I took it on a 600 mile trip just 6 weeks ago.

Turn the headlights on for 5 minutes (engine off) and then wait at least 10 minutes before measuring. It may read full voltage yet still take charge current (capacity)
Sealed maintenance free battery at 100% charge reads 12.80 volts at 70° F
They are going to be throwing the dice looking at everywhere they can to cut pennies......IMHO, if you give them any reason to deny a warranty claim, they will....and that is what they (and others) are doing, more aggressively each day.
Ford's new prez announced they are forming a team to ID customer wants and needs, multiple execs have been fired (again- history repeats itself) for workplace harassment, Ford is again looking for millions of $ is subsidies from local government agencies to help them "build their dream', and they are being investigated regarding the emissions related issues by DOJ......now throw in they are proposing a teaming agreement with VW....whose corporation acted as a conspirator to employ under false names war criminals in executive level positions (paid millions in fines), whose quality control is at best iffy, 4 execs are sitting today in german/US prisons with indictments issued for 20 more execs (re: emissions and animal cruelty related crimes)…...whose profit margins for 2018 were 3.8% and with focusing on electric cars and laying off 30K positions will push their profits to 6% by 2025 (published in their stockholders report)…...this is the last company I would be teaming with IMHO.
The industry itself is challenged beyond belief, in 2017, NADA retained a consultant to look at the industry in relation to the (my words) "failure" of major countries elected officials who have either ignored or abandoned the initial industry specific strategies formed a decade ago within each country...specifically, timeframe for implementation and progressive implementation of advance technologies in the marketplace. Without concurrent guidance, industries now engage in a cutthroat type competition...… the consultants report clearly showed without such restoration, internationally we will go from 50 major car manufacturers to 5 within the decade. VW for an example, has officially stated...it will become the largest mfg of electric cars in the world......and the benefit is multi-fold...it takes fewer components to build the cars, they are more reliable and takes fewer people.....this is a direct quote. IMHO, what we are seeing, as far a battery quality goes is nothing new....but a temp stop gap measure to gain a few $'s to keep stockholders and exec's compensation up.
Ok, I'll shut up now!!!! grin
Just about every battery you can buy in this country is built either by East Penn, Johnson Controls or Exide. Many store brands have batteries built by multiple manufacturers depending on the part number.
My preference is an East Penn built battery. Seems so many of the Johnson Controls ones leak acid anymore and Exide has been junk for years now>
