⚡️ Full Send or Chill Mode? The Definitive Guide to Juicing Up Your Tesla Model 3 to 100%
Yo, what's up, EV Nation? You just copped yourself a shiny new (or gently used) Tesla Model 3, and you're feeling fly. You've got the slick lines, the instant torque, and you're ready to ditch those grungy gas stations for good. But then the big question hits you, the one that causes more drama on the forums than a software update: Can you, like, fully charge your Tesla Model 3? And more importantly, should you?
The short answer, for real, is heck yeah, you can! It's your ride, and the car's built for it. But before you mash that charge slider all the way to "Full Send," let's pump the brakes and talk about the lowdown on battery life. Think of your Tesla's battery like your favorite pair of sneakers—you can wear them every single day to the gym, work, and a black-tie event, but they're gonna look beat faster than if you kept them chill. Charging to 100% daily is basically a high-stress workout for your battery cells, and you don't want to burn 'em out.

🔋 The Battery Lowdown: It's Not a Smartphone, But Kinda Is
Here's the deal, and you gotta listen up. Most Model 3s (Long Range and Performance variants) come with a Lithium-ion battery chemistry, often NCA or NCM. These bad boys do not like chilling out at 100% charge for long periods. It puts a ton of stress on the cells, and over time, that's what leads to degradation—meaning less miles of freedom down the road.
However, if you're rockin' a newer Standard Range or Rear-Wheel Drive Model 3, you might have the Lithium Iron Phosphate (LFP) battery. These are the champions of 100%. Tesla actually recommends charging an LFP battery to 100% at least once a week to keep the car's range gauge (the Battery Management System, or BMS) accurate. Talk about a plot twist! So, step one in this whole saga is knowing what kind of battery you even have. No cap!
Step 1: Know Your Battery Vibe (LFP vs. NCA/NCM)
This ain't rocket science, but it's important. Peep your car's screen or owner's manual. Knowing your battery chemistry dictates your daily charging playbook.
1.1 The Daily Drive Sweet Spot: The 80/20 Rule
Tip: Reread slowly for better memory.
For the classic Model 3 (NCA/NCM battery)—the Long Range or Performance models—your daily charge routine should be all about the "80/20 Rule." This means:
Daily Charge Limit: Set that charge slider to 80% (or max 90% if you really need the extra juice). This is the happy place for the battery.
Don't Go Deep: Try not to let your battery fall below 20% regularly. Running it super low and then charging to the max is a recipe for accelerated wear.
Keeping it between 20% and 80% is the secret sauce for max longevity. Seriously, this is the tea.
1.2 The LFP Battery Exception: Full Charge Friday
If you have the LFP battery (check your paperwork, fam!):
Daily Charge Limit: You can set it to 100% every day if you want, but keep in mind that charging above 90% still slows down way more.
Calibration Check: Tesla says to charge it to 100% at least once a week. This "calibrates the truth," so your car doesn't lie to you about how much range you actually have left. It keeps the computer brain sharp.
Step 2: The Actual Full Charge Mission (Only When Needed)
Okay, so you've got a road trip planned. You're hitting the open road to see your cousins in Boise, and you need every single mile of range. This is the only time you should charge a non-LFP Model 3 to 100%. Don't do it just 'cause you're feeling extra.
2.1 Pre-Trip Prep: Timing is Everything
You gotta be a charging sniper. The absolute worst thing for your battery is to let it sit for hours or days at 100%.
Pro Tip: Aim to complete the 100% charge right before you drive away. This means you should schedule your charging session (using the car’s touchscreen or the totally fire Tesla app) so that the battery hits 100% just as you're grabbing your coffee and throwing your luggage in the trunk. We are talking minutes, not hours!
Tip: Read once for flow, once for detail.
2.2 Picking Your Power-Up Spot: Supercharger vs. Home
Home Charging (The Wall Connector): This is the Chill method. It's slower, lower stress, and the best way to hit 100% without stressing the battery too much. You've got total control over the schedule.
Supercharger (The Full Send): This is the Max Power method. It's wicked fast, especially up to about 80%. But, once you get past that 80% mark, the speed—the charging curve—tapers off harder than a bad reality TV show's viewership. Going from 90% to 100% at a Supercharger can take almost as long as going from 20% to 80%. Use the Supercharger to get to 80% quick, then chill, or just drive off.
Step 3: The Plug-In Process (It's so EZ)
You don't need a PhD for this, promise. This is just for the newbies out there.

3.1 Locate the Juice Hole
The charge port on your Model 3 is on the rear left side, behind a little door in the taillight assembly.
You can open it by pressing the little button on the Tesla charge cable.
You can also tap the lightning bolt icon on the car's touchscreen.
Or, if you’re a boss, you can just tap the little door when the car is unlocked. Some say, "Open juice box!" for the voice command. Try it, you might laugh.
3.2 Plug it in, Plug it in
Grab that connector and shove it in there until you hear a solid click. You'll know it's locked in. The charging port light (the 'T' logo) will start flashing green. Green means go! If it’s flashing blue, the car is connected but probably waiting for a scheduled charge time. If it’s amber or red, something is totes wrong—check your connections or the car's touchscreen for an error message. Don't be that person who leaves a charger half-in, we've all seen 'em!
Tip: Don’t skip — flow matters.
3.3 Set the Limit and Walk Away
Use the car’s big center screen or your Tesla App to slide that charge limit right up to 100% for your big road trip. The screen will tell you the estimated time until it's full, so you can time your departure like a pro. Once it's set, you’re golden. Go grab a burrito, you deserve it.
❄️ Bonus Round: Temperature Tactics
Your battery is a diva when it comes to temperature. It likes to be warm, but not too warm. If it's freezing out, the car uses some of the battery's power to keep itself warm, which is called "preconditioning."
The Power Move: Precondition your car while it's still plugged in at home or at a Supercharger. That way, it uses electricity from the grid, not the precious miles stored in your battery, to get to the optimal temperature for charging. You'll charge faster and save range. Win-Win, my dude.
Charging a Tesla Model 3 to 100% is absolutely possible and even recommended for those LFP-equipped RWD models once a week. For the rest of the pack, save that full charge for the epic road trips where you're gonna hit the road immediately. Keep your daily charging on the DL (20-80%), and your battery will be thanking you for years to come!
FAQ Questions and Answers
How does charging to 100% impact my battery health over time?
Charging to 100% (and letting it sit there) frequently can accelerate battery degradation for NCA/NCM batteries. It puts the cells under high voltage stress, which shortens the overall lifespan and available range of your battery pack. Think of it as leaving a gas tank completely full for a month in the hot sun—not ideal for the chemical structure inside.
Tip: Use this post as a starting point for exploration.
Is it better to charge my Tesla every day, or wait until the battery is low?
It's better to charge frequently. Plug in your Tesla Model 3 whenever you can (like every night at home) and set your daily limit to 80% (or 100% for LFP models). Lithium-ion batteries prefer frequent, shallow charging sessions over infrequent, deep-cycle charging (going from nearly empty to full).
How can I make my Tesla charge faster at a Supercharger?
The fastest Supercharging happens when your battery is at a low state of charge, usually between 10% and 50%. The charging speed will drastically taper (slow down) as you approach a full charge. For road trips, it's often faster to charge from 10% to 80% and then drive to the next charger, rather than waiting for 100% at the first stop.
What is the difference between a Model 3's LFP battery and its NCA/NCM battery for charging?
The NCA/NCM (used in Long Range/Performance models) is the "less is more" battery—daily charging to 80-90% is recommended. The LFP (used in newer RWD models) is the "full send" battery—Tesla recommends charging to 100% at least once a week for calibration and daily use, as it's more durable at a high state of charge.
Should I leave my Tesla plugged in all the time at home?
Yes, you should! Tesla actually recommends keeping your vehicle plugged in whenever possible. Once the set charge limit is reached, the car uses power from the wall outlet instead of its battery to run its internal systems (like Sentry Mode, climate control, and battery temperature management), which minimizes battery drain (phantom drain) and stress.
