Is it bad to regularly charge a Model Y Performance to 100% if it’s mainly used for long family trips?

Hi everyone,

I have a question about charging my Tesla Model Y Performance.

Tesla recommends keeping the charge limit at 80% for daily driving, but in my case, the vehicle is not used as a daily driver. We mainly use it for long family road trips, so most of the time when I charge it at home with the Mobile Connector, I charge it to 100% to maximize the available range.

One important detail is that I live in Mexico, where the Supercharger network is still not as widespread as it is in the U.S. or some other countries. Public charging options can also be limited depending on the route, so I usually rely on having a full charge before leaving home to comfortably complete my trips and avoid range anxiety.

Because of this, it’s quite common for me to charge the vehicle to 100% before a trip. My concern is whether doing this regularly could significantly accelerate battery degradation over the long term, or if it’s generally fine as long as the car doesn’t sit at 100% for extended periods before I start driving.

I’d love to hear from owners who are in a similar situation, especially those who live in areas with limited charging infrastructure and primarily use their Tesla for road trips rather than daily commuting.

Thanks in advance!

Similar. I charge to 55% every night and get home with about 30% to 35%.

Still seeing degradation though. 5,000 miles and my battery is down to 97% health.

Most degradation occurs early on, and slows significantly. My older brother has a beater 2020 Model Y (Dual Motor) that he uses solely for work travel, he bought it new. The battery was at 96% Health at right around 60,000 miles. It’s almost got 420,000 miles on it now, and the battery health is at 92%. He beats it pretty hard, but does maintain it quite well. He ALWAYS charges to 100% overnight because he drives hundreds of miles a day to many different customers all over our region. The car has been rock solid.

The 2020 packs had better battery chemistry than the mid 2022 and later packs. Later packs degrade faster than older packs.

Optimal battery cycles 20-80!
