I've had my Mach E for about four years and nearly 100k miles. I've never worried about the 80% charging and always charged to 100%. I can't tell a huge difference in the range after four years.
You can get an Deka AUX18L from batterymart.com for $159 shipped to your door. Deka is the OE manufacturer of the BMW battery for the i3. My original battery lasted 7 years, it’s a no-brainer.
I had the same issue with my MY2024 XL Hybrid constantly going into deep sleep mode. There is a recall for MY2022 and MY2023 Mavericks Hybrids due to a bad 12V battery. I took it to the dealer anyways... After their battery test, mine FAILED and they replaced the 12V with an new AGM battery (free under the OG 3yr/36k mi warranty).
XLT 22 Hybrid, aside from the shitty OEM battery that was just swapped out to an AGM one and the numerous recalls, still loving my truck. Gas is still great and the bed works very well.
I use Deka sealed batteries so less offgassing messing up terminals.
Had the OEM battery until 2021 before it died. I think six years in the NE is pretty decent for an OEM battery. 78k miles on the truck so far. No issues with the starter or the new battery since replacement.
Mine did this around 30k miles. The battery was swollen and definitely the problem, but all battery scanners showed that it was good
In keeping my 07 f150 xl long bed regular cab till my feet go through the floor and I gotta push it up the exit ramps.
I met a guy with a 25, trying to get a replacement battery that has to be done at the dealership.
A $80k truck that you're basically renting from Ford because of all the gatekeeping software crap- and most of it experimental with the buyers being the test market.
Neighbor has a F-150 lightning.
The battery on it has been replaced twice in 3 years. Its spent a few months now cumulatively at the dealership waiting for the new batteries, and various other repairs.
Warranty covered my 2022 Mach-E battery replacement but it would've cost $12k out of pocket.
