"Proactive" 12v battery replacement - good idea or overkill?

[RickMachE]

Because, if you did, Skynet would become aware? What is that, rule #94?

I think that’s a Ferengi rule of acquisition.

My wife and I took delivery of my wife's 2022 MME GT in July of 2022. So far we have had no problems or issues with the car at all.

I recall reading in one of the tagged 12v battery information posts on this forum that 12v batteries usually last 2 to 2 1/2 years. Given that the 12v battery in our MME GT will be 2 years old this coming July, I am considering proactively replacing it even though the car is functioning fine.

My main concern is that I don't want the 12v battery to die unexpectedly, leaving my wife or me stranded and in need of a tow. I think replacing the 12v battery proactively would give me peace of mind.

What do you think? Is this a good idea or overkill?

Thank you,

I think it would be a better idea to carry a small jump box for emergency starting if you're that concerned.

Where would you effectively carry it?

Frunk or under the rear trunk floor.

Right, but then how will you access it if the LVB voltage has become too low to open doors?

Read your manual on how to jump it by accessing the contacts near your front bumper.

OP - it's overkill, unless you're getting a bunch of warnings in Fordpass. Otherwise just take it to a local auto parts store for a load balance status. FYI - our 2021 Job 2 car nearing 3 yrs and still on original LVB.

I treat the MME like my previous cars, I routinely check both tire psi, LVB, fluids, etc once or twice a month but all dependent on use case. Also use Ford.com to monitor the LVB %, look for any anomalies

I read the manual. It bummed me out, because it left me wondering what to do with my NOCO Boost battery pack. I just leave it in the garage now. ?

Hard to get in the car to get it when the battery is dead...

You're right there. If there is some kind of warning, you could carry it in the cabin and remove it when exiting the car. I haven't experienced a dead battery yet, I do monitor the soc in Ford.com.

The thing is, there is relatively little warning. Some people will experience a spate of DTCs being thrown, but that’s before it goes dead. Charge that baby as soon as that happens. ?‍?

The replacement 12V battery is $187.50 MSRP. (kinda expensive for what it is)
For something low cost, I would have no problem proactively replacing it, but for an expensive component, I will wait until replacement is absolutely necessary.

Does that include labor? AFAIK, the MME battery replacement requires complete removal of the frunk tub which I doubt is something most shops are going to want to do as part of a “free installation”

Put a 12v trickle charger on it as this can be found for under $20. Your choice of charging scheduling weekly, bi weekly, monthly?

I have a 2021 GTPE that I picked up in Jan 2022. I plan to replace it when I take it in for the three year check up which will be Jan 2025. I don’t drive much and only have about 15000 miles so I think the three years will work fine.
