• They immediately lose 10% of their total battery capacity permanently. Google “tesla range loss” if you don’t believe me. Tesla warranty only covers more than 30% capacity loss up to 100k miles so the average 10% loss within the first year (I lost it within the first 3000 miles) is completely within spec.
• Cold weather destroys range. So if you live in the north expect to lose about 33% of your range on days the temp drops below 40 degrees.
• Driving faster than 60 to 65 mph destroys range. If you drive 80 mph expect to get about about 75 miles using 50% of your battery capacity. Get ready to be cursed regularly on the freeway if you drive 65 mph.
• You’re instructed to not charge it to more than 80% capacity or let it drop below 20% capacity or it damages the battery. So you really only have 60% of the capacity to work with.
• Real world range is 66% of whatever the battery shows. If my battery says I have 198 miles to 0% that means I have 132 real miles.
• Supercharging is 90% as expensive as gasoline and damages your battery and takes more than an hour.
• Anything that heats up the battery is bad for its health. Ie supercharging, parking the car in the sun, doing multiple fast launches.

So take my “long range” tesla which has 330 miles range new. It lost more 10% of that range within 2 months of ownership and now shows 290 miles range at 100% charge. Furthermore I’m not supposed to charge it to 100% or let it drop below 20% so my range is now 60% of 290 miles so something like 180 miles. Also real world mileage is 2/3 of that range so I only get something like 120 miles usable range which means I can’t drive further than 60 to 75 miles away from home.
