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.
Even in the colder weather now, I'd be getting 400+ km on a full charge in my BEV (Mustang Mach e). But I only charge once a week (Fri night), to 80% to help with battery life; costs about $3 per week to get an extra 200-300km.
Always read your manual/mfr suggestions for battery charging and longevity.
For Li-ion you generally should charge no more than 80% (some mfg hide 10% via software like Ford, so you charge to 90%). Also, limit fee cycling these types too, regularly you should DC to about 50% max. Occasionally deep cycling and full charging is fine. Should limit DCFC also.
I use a Group 27 battery in my Mustang and have found Bosch to work very well for me.
My last experience from them was a yellow top from 2015 that I got for my '01 Mustang. Had it for 4+ years starting up just fine and survived despite having been drained dead 5 times or so. Sold the car before the battery died.
Warranty covered my 2022 Mach-E battery replacement but it would've cost $12k out of pocket.
DO NOT buy a red top Optima. They haven't been good or worth the price in like 15 yrs.
my optima red top died after 3.5 years and 4800 miles. When it wasn’t driven, I had the battery disconnected. For a $240 battery, I’m extremely disappointed. FWIW, the battery was in a restomod 66 mustang. I bought it in March 2018, and the warranty expired in March 2021.
