How often should you charge to 100% , if you do not go on a road trip ?

[CanadianMetal]

I have owned my 3 for almost a year , and have NEVER charged it to 100% , I have it set to 80% and just leave it there.

Is it advisable to once in a while, charge the car to 100% (or even 95% etc.) , if you don't need the range ?

Do you need to do this once in a while to "Re-balance batteries" , "Exercise" the cells , "memory" or some other positive reason....

If so , how often should I be doing that ? Once a year , once a season, every 2 years or ?

Read the manual. Charge to 100% when you're going on a longer than normal trip - 80-90% for daily use.

I second read the manual.

But it doesn't really matter. Just drive the car and don't worry about it.

No. Nothing beneficial in doing this. For their health and longevity, the batteries prefer to stay toward a middle-ish state of charge.

The battery estimator will sometimes drift, and people will see the number of rated miles starting to drop by a few, but that is just software estimations. People doing these exercises of running the battery high and low is just to make themselves feel better.

As noted by Service Center, 90% should be your routine.

Service appointment for 12 month old Model 3 for range loss /invoice for out of warranty inspection?

If you need to charge to 100% because for the road trip then do it but you should not do it for no reason.

...Do you need to do this once in a while to "Re-balance batteries" , "Exercise" the cells , "memory" or some other positive reason....

No. Those are bad reasons. If you don't need the range to arrive at the next Supercharger, those above reasons are all bad and not positive at all.

I'd recommend quarterly. But it is far better to actually take a road trip in the car.
