I read thought the charging section of the manual and it states that in everyday use you can use the full state of charge window however…. They recommend setting the charge limit for overnight charging to less that 100%, see below for info from the manual. I know that 80% is the common limit recommended for DC fast charging, does it also apply to AC home charging at much much slower rates? Is 90% ok for AC charging or should one stick to 80%? I generally go by what the manufacture recommends but less than 100% is a bit a vague.


PRESERVING YOUR HIGH VOLTAGE BATTERY
When using the battery at a low state of charge, your vehicle could start disabling accessory features to protect battery life.
If your vehicle reaches a 0% state of charge, recharge your vehicle as soon as possible.
In everyday use it is acceptable to use the full state of charge window, however there are a few best practices we recommend in order to maintain the health and life of your battery.

Overnight Charging

You can increase the longevity and performance of your high voltage battery by using the charge scheduling and departure and comfort settings on your touchscreen or in the FordPass app.
With Charge Scheduling, you can improve the high voltage battery's longevity by delaying the start of charging and setting a maximum charging limit. We recommend you set your preferred charging times to be at least 2-3 hours after your typical plug in time. This allows the battery to cool before charging begins. Additionally, setting the maximum charge level to be less than 100% for everyday usage reduces strain on the battery.

With our Mach-E we were recommended to charge to 90% at home. That has been working well for us.

Also I only charge it 2-3 times a week. Though in the coldest parts of winter (we’re in WI) it’s always plugged in when not in use.

Lithium ion batteries are happiest around 50% and really unhappy when they sit near zero or 100%. 100% is fine if you plan a long trip and will leave right away. 90% is better. 80% is even better for regular use. However, it really depends on your needs. If you only charge 2-3 times per week, you can probably limit to 80%. If you drive near the limit every day, you may need 90% or even more.

I think Ford has dummy proofed this. The battery pack is 140 and useable 131 which makes “full” 93%. When you fast charge, you have to request a 1 time 100% charge (which isn’t even actually full ie 93) otherwise you are charging to 90% (which is 117). Ac at any level it will let you go to 100%(93). Don’t over think it.

I have the SR pack do you know the actual specs for it? I believe it is 98kwh usable and assume that Ford holds some in reserve at both ends of charge 0 and 100% the question is how much did Ford leave in reserve.

ok I been slow charging (240 30 amps) to 100 as that is where the app was factory set for about a week of ownership, am I to understand I should not be charging to 100? seems weird as I would think ford would have (with software) made 100 percent lets say really only 90 percent. Also I am trying to find out if I can charge at home in the rain, as it started to rain so I stopped charging and pull the plug closed the door.

Ford recommends charging to <90% unless you need to top it off to make it to your destination. And charging in the rain is fine, the J2772 connector is designed to be used in all weather.
ahh ok I will look into settings to stop charging to 100, I assume via the app is easiest. Thanks for this I had no idea 100 is not good for the battery.

UPDATE: I hit the Stop Charging button on the app and it stopped charging, and also moved from 99 to 100. 🙄🤷🏻‍♂️

I’m at about 1K miles and have typically recharged to 80% at 48 amps when I’ve needed. But I used the 110v mobile charger and let it ride the last two days. I set it to 100% just to exercise the battery a bit since it’s new, and I’m not getting it to 100%…it’s staying at 99% and won’t get to 100%. Anyone else experienced this? It’s not the extra 3 miles I’m looking for, but more about that it won’t get to 100 and it should be able to. I fully understand charging to 100 is mostly unnecessary and not typical, but shouldn’t it be able to get there? Below you’ll see it showing that it’ll hit 100% by 12:00…but it won’t. It has missed the other stated timelines throughout this morning.

Hi there. This battery concern doesn’t sound like something we want you to experience with your F-150 Lightning. Could you please send us a PM with your VIN and the name and location of your Ford dealer? I'd be happy to look into how I can assist you on my end.
