12V Battery replacement with H4

[chl]

Damned if you do damned if you don't! Good things we have DC/DC converters that will keep our batteries perfect for ever! Not!!!

Alas.

Like the Greeks (or somebody back then said) "all things in moderation."

Not too hot and not too cold, the Goldilocks principle of battery maintenance.

It is written that modern smart battery maintainers are the ticket to near eternal battery life.

The Zen of Lightning maintenance, if you will.

NOCO to the rescue!

@Adventureboy I've started getting occasional "system off to preserve power" messages so I know it's time to finally swap out my 12v. I assume no news is good news here but I wanted to ask you (or anyone else who put in an H4) if you have any regrets so far? I think I'm going to go this route in the very near future.

No regrets except I wish I went larger than H4!

I mean with the winch I just purchased and if I ever decide to get a light duty plow that is powered, I'd need it.

Zero regrets. I monitor it daily and the truck charges it fully. No more messages so far.

It's a good thing he used one of them extra strong H-V-A-C zipties, because I sure wouldn't have trusted a standard one.

Bit too much jerryrig for my taste.

My 12 Volt battery went bad, bulging sides, Only 2 years old. Replaced with a new Motorcraft AGM H3 under warranty. This battery went bad after two weeks with bulging sides. Battery saver notices showing up on Ford Pass. I replaced it myself with a H4 AMG battery that says it's electric & Hybrid compatible. I also reset the BMS by using the 5 bright headlight switch followed by 3 brake pedal trick. It seemed to reset the BMS. I had to cut off the spacers in the tray so the larger battery would fit. I've attached photos.
