No it will not “damage” your truck. Yes it will promote additional battery degradation then not doing it.

Once a week 100% likely won’t be the end of the world, but if there are alternatives, such as charging at the destination. That way you accomplish what is needed but don’t prematurely degrade the battery.

On L2 chargers speed isnt nearly as important.

Every lithium battery suffers degredation. How MUCH is the question. Things like temperature, big charges (10% to 100%), and having the battery at 100% all cause that to happen somewhat faster. However we are talking 10, 15, 20 years down the road here.

With these batteries small charges more frequently is preferred. Charging once a day, heck twice a day, is preferred to charging a big charge every few days. If that works for you it is the recomended approach, if not, do what fits your lifestyle. You won't damage anything or ruin anything by charging to 100% once a week. But, in 20 years you may have 85% battery capacity, instead of 91% (numbers completely made up).

Personally, I probably don't plan on keeping my truck long enough to notice the battery degradation, so I charged to 90% everyday. I figure if my charging habits make the battery go bad before the warranty's out then I get a new battery before the warranty is done lol.

I've been driving electric for the past 14 years... 1st and 2nd generation Chevy Volt + two Chevy Bolts and now my Lightning. I always charged my cars at home (L2 50 Amp) to full 100% and never experienced any battery degradation.. I used all my Chevys for in-town driving and never held them for longer than 3 years.. Fact is that I also use Tesla Superchargers and never push it past 80% but that is only because it dramatically slows down the charging rate... And I don't intend on keeping my truck past the battery warranty expiration anyway so I never really worry about battery degradation.

I typically charge 60/70 % to 100%, because the vehicles are useless to me if I can’t leave in a moments notice and drive 200 plus miles. My 22 MME now has 60k and my 23 Lightning has 30k and I haven’t noticed any battery degradation on either. I’m guessing that by the time I need to address battery degradation, I will be wanting a new vehicle or there may be some battery aftermarket options. As the MME passes 100k it will also have saved me $10k plus in fuel and maintenance, and the Lightning a little less due to less efficiency. If they surpass 100k with little degradation, I may just charge on to 200k. I just think fast chargers (for me) are not part of the equation because I use them so infrequently. But ultimately, it is all one great experiment we are running in real time! The data keeps coming in!

No, it’s not gonna have much adverse affect at all, if you drive soon after it’s finished charging to 100%.
Remember 100%, in this truck, Is NOT really 100%.
Letting it sit at high LOC is when the degradation happens.
If you need it, take advantage of the capacity you bought and make the most out of it !!

Charging at 240V (any amperage) is much preferred over 120V.
it’s easier & more efficient for the onboard charger.

This is one of the most considered topics on the form. As stated above, only time will tell. I doubt, at this point if anyone really knows the exact answer.

So true, I’ve done the same thing for 20 years.
And in all of those cars 100% is not really 100%.
When I bought my first hybrid electric, so many people were telling me I’d be buying a new battery every 2 years, and they cost 10’s of thousands of dollars.….blah blah.
Never happened. I drove it for 200,000 miles, never saw degradation and sold for just under 50% original price! Talk about a car that paid for itself, yes it did. Similar results with theVolt and Tesla that followed.

Everybody needs to read the owners manual.
