Upgrade Battery

[BlkMach10510]

I'm confused after reading thru all the posts , I just replaced my battery yesterday, I had the old one on a battery charger / maintainer, for the year I've had the car( 2021 Mach1)while not in use, no idea of the maintenance to the battery prior to my purchase. I must say only during the day the charger/ maintainer is plugged in, before bed I unplug . (The reason why I do this is my neighbor down the street , I'm not sure exactly what happened , but he was in the garage (electric golf cart ) plugged it in or checking on the charge , it blew up knocking him out , started a fire burned the garage killing him . Was a very sad deal 91 years old ) . Anyway my old battery I would check before bed the volts would be 12.5 abouts the next morning down to about 12.3 , plug back in for the day and so on . Fast forward the other other morning it was at 11.9 , plugged in, evening up to 12.4 about's , unplug at bedtime, yesterday morning same routine checked voltage 11.2 volts , only thing I can figure is it finally died . I put a new battery in , reset the BCM drove her around 20 or so miles , this morning 12.7 volts , so I plugged a tender in and it's been red about 6 hrs now and voltage reads 13.41, waiting for the light to go green .
Maybe I worry to much , my other neighbor buddy keeps his car and truck plugged in 24/7 while not in use and sometimes he's gone months at a time .

Yea, when I bought my new battery I would figure it was almost charged but it took hours to get to 100% charged.

Thanks Brother , I just took the battery off the tender and put on the smart charger (most likely smarter than me ) it indicates at 80% so apparently a way to go to 100% , still worries me charging voltage fluxuating 13.8 to 14.3, I hope that's normal .

Ya Im with you , I'm use to 60s and early 70s cars , but done with them, at 70 I can work on them any longer. My wife's 22 Blazer and my Van I don't worry about and they sit days idle, but this is my specialty car now , more tech more potential issues.

If someone could give me a 1969 BOSS 429 I would be fine, pretty sure no bms.

Very nice .. My Mach is my 1st Ford and it's Awesome.
Sure takes a long time for the battery to reach 100% still charging at 80% and 14.25

My battery tender took about 9 hours to go to 100% and the battery was new.
