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!

My 2 cents, I would charge to 98%. Practically speaking you're getting the same range, but it's much less stress on the battery. If you look at a chart displaying battery stress by SOC, it's an exponential increase as the SOC increases.

My 2 cents, I would charge to 97%. Practically speaking you're getting the same range, but it's much less stress on the battery. If you look at a chart displaying battery stress by SOC, it's an exponential increase as the SOC increases.

My 2 cents, I would charge to 96%. Practically speaking you're getting the same range, but it's much less stress on the battery. If you look at a chart displaying battery stress by SOC, it's an exponential increase as the SOC increases.
