Battery maintenance !!!

[Green Nv]

Hey, do ya all remember when your vehicle battery finally died and all you had to do was just put in a new one and that was it !!!
Now ya gotta pump your brakes, flash your lights, drive the car straight for 2 miles over 40, reset your windows and probably something else I missed, oh, and don't forget, if you have to disconnect your battery leads you gotta wait 3 minutes after you turn off the vehicle or it'll wack it out !!!
What a crock of shit !!!

When I installed my High Mount Intercooler I disconnected my battery and did not have any issues when I reconnected it. When replacing a battery in any newer car the first thing I do is take the fob out of the vehicle and put it on the workbench. Disconnect. Always negative first then positive. When done re-connect. Always positive first and negative second. Then get the fob to start it.

Sounds more like the Bronco "loose" fuse box maybe????


By the way why was the battery dead??? Are you sure the battery did not just need recharged because it had been sitting for a while without being disconnected??? New vehicles have a tremendous draw on the battery and if not driven the battery should be disconnected. IMO

Still running the factory battery on my 2012 Sierra. Does not have on star...

Isn't technology grand!

Could be worse, my BMW battery needs to be programmed to the car with their software. I don’t have that software so the battery plus the installation and programming $460.

BMS system?

How do you feel about using a Battery Tender in lieu of disconnecting?

A tender is fine. Need a power source (obviously). And when you do get one make sure it is at least an amp and a quarter (1.25 amp). I know those small 750 milli amp ones have a car on them but they are not enough to keep up to the draw.

I will probably just use my NOCO jump starter attached to the wires before disconnecting them. The BMS will need still to be reset one way or another, but nothing should lose its memory in the vehicle.

Agreed, I've even quit using the 1.25 A Tenders on newer vehicles with all their electric demands. I buy 2-3 amp models when I need a new one now since I had a 1.25 die on my Sprinter van.

I just learned that after I let my Bronco sit for 6 months without a tender and wasted the battery. I cheaped out and put a regular lead acid in instead of AGM ($80 suckas!) and thought maybe it caused all those issues, but no, the thing is just too smart and had to sort itself out with driving.

Probably last longer than the AGMs too

For the record AGM have different charge requirements than a flooded battery. The Bronc is designed to charge an AGM.


I'm not saying it won't work but if you have issues.........

I'd keep AGM simply because I don't like having to clean battery terminals. I switched to AGM in my MR2 back in the 1993 and in my Subaru after the original battery failed in 2004. No regrets.

The probem is Ford's battery management (manglement?) system, not the battery technology.

True. But I would bet on “it’ll be fine”

There is a toggle for it in Forscan, I dunno if it does anything though
