Taking Care of the Battery - Suggestions from Battery Engineer from Lucid

This question comes up a lot for people new to EVs, for good reason. It can be daunting trying to learn how to take care of such an expensive piece of kit.

But let me settle your mind quickly: Unless you are a complete dolt who treats the battery with zero regard, you'll be just fine.

All of the advice given by the experts is true. But none of it really matters that much in the scheme of things.

It's not like constant DC fast charging will drop your battery percentage to 10 percent of what it used to be. It'll just drop it to 89% percent of what it used to be instead of 90%.

The battery is guaranteed for 8 years. The car's computer won't let you do anything to damage it too badly, unless you are really trying. Lucid are on the hook if it goes bad for a long time. They have a vested interest in protecting your battery, too.


So take a deep breath. Charge as needed. Stop worrying.

For daily use, set the charge limit to 80%. (If you have a level 2 charging station at home, just plug it in every night and let it top off to 80. Set it and forget it.)

On the occasional road trip, use fast charging to get where you need to go. If that means you need to charge to 100% in order to get to the next charger, or you need to drain down to 6% to reach the next charger, so be it. IT WON'T MAKE ANY APPRECIABLE DIFFERENCE. I promise you.

The bigger problem with charging to 100% is that it takes too long and will inconvenience others. That's a way better reason to charge to 80 or 85 on a road trip. If you can get to another charger with only 80%, by all means, only charge to 80%. It'll be faster to stop twice, anyway. And the rest of us will thank you.

Constantly fretting about the battery takes away the single biggest advantage of owning an EV. If you can charge at home, you'll quickly learn that you just about never have to think about power at all. The car will have 80% every morning, which is further than you are likely to go on the vast majority of days.

I'll take that over going to a gas station 7 days a week and twice on Sunday.
 
Did I teach you nothing? More speed!

I cannot swear to the accuracy of this report, but it's worth considering. It's from INSIDE EVs dated June 19, 2025:

According to Geotab, a United Kingdom company providing vehicle telematics, most EV batteries can last 20 years with minimal annual degradation. That’s six years more than the average car age in the United States.

Over this generous timespan, EV batteries suffer from about 1.8% degradation per year. This means that you’ll lose 1.8% of the original range every year–not ideal, but certainly not a dealbreaker. After 20 years, if nothing goes catastrophically wrong, you can still enjoy 64% of an EV’s original range. The data comes from analyzing over 10,000 EVs.

Think also about the transmissions and oil changes you’d have paid for in a ICE vehicle over 20 years.
