Factory battery life

[Nytimes770]

I noticed today ASS isn’t on when I start the car but if I push the button it does come on. I didn’t test it to see if it actually works though.

I plan to keep the car for no more than 2 more years. I guess I will need to replace the battery before then, and one change will be enough.

On ours, regardless of battery charge level, when you push the button, it lights up 'off' and, when driving, the ASS symbol in the instrument cluster displays with a diagonal slash through it

I habve a 2019 and am still on my original battery. I put my battery on an AGM tender about 1 night per mionth and I think that significantly improves battery life.

Which one do you use?

I had hoped to join the forum for fun stuff, but alas. I just bought a 2021 with 40k miles about a month ago. This week, I noticed "deep sleep mode" on the app but no other symptoms. I took it to Auto Zone. They told me the battery tested good but needed a charge. Took it to a local mechanic (at closing time on Friday) who quickly checked and said the alternator seemed to be charging and everything looked okay, but bring it back if something came up. Didn't drive it yesterday and it wouldn't start last night.

I'm a non-car knowledgeable girl but can follow simple instructions. Searching around there seem to be '21 F150s with known drain issues, and a service bulletin, but I'm not finding much on the Expys. Any ideas? Battery still bad on a 2 year old truck despite what Auto Zone says? (July 2021 build date)? Some accessory not turning off (can't see anything)? Some wire or relay not functioning properly?

Recommend getting an appropriate trickle charger, Battery Tender is the one I use. Use that charger, depending on your driving routine, at least once a month. I don't put many miles on mine so I usually charge every two to three weeks. Based on the other feedback from Auto Zone and local mechanic you should be ok if you do that.

So you think nothing is actually wrong? I drive around town daily, short trips, running kids around and to different work locations. Then 30 min drives 2-3 times a week. We jumped it and it ran for 5 min or so this morning around 8:00 then by noon it wouldn't start, but it tried.

And thanks for the welcome! Glad to be here despite kicking at my Expy every time I walk by it today.

3.5 years for me. ASS stopped working after 2.5 to 3 years.

Amazing how much the these rolling computers draw battery charge just by sitting.

My 02 Mustang can sit for Weeks and still start up on the first turn no problem. Cars are certainly not as reliable as they used to be and cause 3x more

Are there any settings that would help with battery drain? Seems like you could shorten the interior lights staying on or choose to disable some features or something.
