Life is Strange (battery stuff)

Had a nice list of on-the-road chores to attend to today. First on the list: "load-test battery".
So I'm really gonna get some stuff done today, jump in the '94 Tbird LX V8,
turn the key and ... it does about 1/2 of a crank rev and dies a horrible death.
7 year old battery is presumed dead, kaput, pues muerta. I put it on a trickle charger anyway.
Does anybody know:
Does Johnson Controls still make a good battery for Motorcraft?
Does Johnson Controls still make a good battery for Sears Diehard?
I'll likely have to lug a new battery home and install myself.
The ECM will reset to default (factory) settings? Any particular worry about re-establishing the kinds of settings needed? 'Boid had 65k mi. and was running OK.

I never see a battery die that way, I see bad connection with that symptom... it just has a short cranking life when it's dying.

EVERY Walmart battery I ever bought lasted longer than ANY Diehard I ever had.
YMMV.

Dont sweat it.. most annoying is the radio. Might want to clean the MAF first

That's what I was hoping for. Didn't get it.
I lugged a new Motorcraft 650 cca home and all is fine (except I'm $107 lighter).

I got 7 years from my Diehard Silver (no complaints).
If I could determine that a Walmart battery was not made by, say, Exide, I'd likely buy from 'em ('tho I'm no Walmart fan).

Took 20 min. to get it in. Musta reset, but no problem. Still haven't reset the radio.
Cheers, Puddin'

Lead acid batteries are known to suffer a "sudden death". I once had a '97 Chevy Geo Metro I bought new. It had a four year battery & just over four years after I bought it, after refueling at a gas station for .99 cents a gallon (never see those daze again) the battery went south. had to coax it with a jump start. Replaced it & off I went until I sold the vehicle & bought a new 2004 Ranger.

The heavy battery made up for that.
