TL;DR
- Use the daily limit your own Tesla recommends. Your touchscreen shows it on the Charging screen, and it depends on the battery in your car.
- For cars with an 80% recommended daily limit, Tesla says to keep it at 80% and raise it to 100% only when you need it, such as before a road trip.
- Cars with an LFP (lithium iron phosphate) battery are the exception: Tesla's manual says to keep the limit at 100%, even for daily use, and to charge to 100% at least once a week.
Every Tesla lets you choose how full the battery gets when you plug in. It is one slider, but it is also the setting new owners ask about most: should you charge your Tesla to 100%, 90% or 80% every night? The answer depends on which battery your car has, and Tesla tells you which one it is. This guide explains how to find your car's recommended limit, what Tesla says about each battery type, and what the choice means for your range and your electricity bill.
What should I set my Tesla charge limit to?
Set it to the daily limit your car recommends. Tesla's home charging page says to charge to the limit that fits your car "based on the installed battery," and that your touchscreen will display the recommended charge limit for your battery. That guidance covers every Tesla, from Model 3 and Model Y to Cybertruck, Model S and Model X.
For a car whose recommended daily limit is 80%, Tesla's range tips page is direct: keep the limit at 80% for daily use, and only raise it to 100% when necessary, such as before a long road trip. The same page adds three habits that apply to every Tesla:
- Avoid letting the car sit near 0% or 100% for days or weeks at a time.
- Charge as often as you can, rather than running the battery low before you plug in.
- Charge at home when possible, and use Superchargers for road trips and long drives.
How do I know if my Tesla has an LFP battery?
Some Teslas use a lithium iron phosphate (LFP) battery, and it follows different rules. There are two quick ways to check:
- Look at the charge slider. Open the Charging screen on the touchscreen or in the Tesla app and drag the slider. According to InsideEVs' summary of Tesla's US owner's manual (December 2021), a battery image marked "50%" and "100%" means an LFP battery, while one marked "Daily" and "Trip" means it is not LFP.
- Check the vehicle details. The same manual guidance says to go to Controls > Software > Additional Vehicle Information. An LFP car lists "High Voltage Battery type: Lithium Iron Phosphate." Other cars don't list a battery type there.
Tesla has changed batteries between model years and trims, so check your own car rather than going by what a friend's Tesla does. Screen labels can also change with software updates; the recommended limit your touchscreen shows today is the one to follow.
Should I charge my Tesla to 100%?
It depends on the battery, and the two answers are close to opposites.
| Your battery | Daily limit Tesla recommends | When to go to 100% | Source |
|---|---|---|---|
| Recommended daily limit of 80% (shown on your touchscreen) | 80% | Only when you need it, such as before a road trip | Tesla range tips |
| LFP (lithium iron phosphate) | 100%, even for daily use | At least once a week; if parked more than a week, charge to 100% at your earliest convenience | Tesla manual, via InsideEVs |
| Any battery, parked for more than two weeks | About 50% | Not while stored; set the limit to 50% and leave it plugged in if possible | Tesla range tips |
Why the difference? Tesla's manual says that following the LFP guidance maximizes available range and improves the car's ability to estimate its state of charge and range accurately, as InsideEVs reported. For other batteries, Tesla's range tips page notes that charging habits can affect battery health over time, which is why it asks you not to leave those cars sitting at 100%.
A worked example: what 80% means for a Model Y
Numbers make the choice easier. Take a Model Y Premium All-Wheel Drive. GetTesla's calculator data lists its EPA range at 327 miles and its EPA consumption at 27.4 kWh per 100 miles, from fueleconomy.gov, as of October 4, 2026. Tesla's range tips page explains that the miles shown in the car are based on EPA test data, not your own driving, so treat these as rated miles:
- At an 80% limit: 327 x 0.80 = about 262 rated miles each morning.
- At 90%: 327 x 0.90 = about 294 rated miles.
- At 100%: the full 327 rated miles.
Now say you live in Virginia and drive 40 miles a day. Those 40 miles use about 40 x 0.274 = 11 kWh. At Virginia's average residential rate of 16.83 cents per kWh (U.S. Energy Information Administration, as of October 4, 2026), that is about 11 x $0.1683 = $1.85 a day to put back overnight. EPA's figure is measured at the wall, so it already includes charging losses.
At 80%, you leave home with about 262 rated miles and come back with about 222. That is a wide cushion for errands and detours, and cold weather or highway speed will eat into it, so leave yourself room in winter. Our guide to preparing your Tesla for winter range loss covers how much.
To run the numbers for your own car, state and charger, put them into the charging calculator. It shows how long a top-up takes and what it costs.
How to change your Tesla's charge limit
Tesla's support page gives the steps: open the Charging screen on the touchscreen or in the Tesla app, then drag the slider to the limit you want. The car remembers it for the next time you plug in. A few habits make it easier:
- Plug in every evening. Tesla's home charging FAQ recommends plugging in every evening to top off the battery. Your car stops at the limit you set.
- Raise the limit the night before a trip, not days before, so the battery doesn't sit full.
- Charge on a cheaper rate. Tesla suggests matching your charging schedule to your utility's off-peak hours. See how utility EV rates work.
If the last stretch to 100% seems slow, that is expected. Our explainer on why a Tesla charges fast to 80% and slowly to 100% covers why, and two settings that quietly drain your battery while parked explains where overnight miles go.
Common questions
Is it bad to charge my Tesla every night? No. Tesla recommends plugging in as often as you can, and its home charging FAQ suggests every evening. Tesla's range tips page also says frequent charging is easier on the battery than running it low before you plug in.
Can I set 90% instead of 80%? The slider lets you choose any level. Tesla's current advice for cars with an 80% recommendation is to keep 80% for daily use, so go higher on days you need the extra miles, then bring it back down.
What if I'm going away for a few weeks? Tesla's range tips page says to leave the car around 50%, set the limit to 50%, and keep it plugged in if possible.
What to do
- Open the Charging screen and note the recommended limit your touchscreen shows.
- Check whether your car has an LFP battery (slider labels, or Controls > Software > Additional Vehicle Information).
- Set the slider to match: 80% for an 80% car, or 100% for an LFP car with a full charge at least weekly.
- Run your own commute and rate through the charging calculator to see your daily cost.
