Should You Charge Your EV to 80 or 90? Read This First!

As electric vehicles continue to gain popularity, one of the critical questions that EV owners face is how much to charge their batteries. It’s not just about plugging in and waiting; it’s about optimizing battery health and driving range.

Two common charging strategies are to charge your EV to 80% or 90% of its capacity. In this article, we’ll explore the factors you should consider when deciding between these two charging levels to help you make an informed choice.

Charging to 80% or 90%: Understanding the Basics

Charging an electric vehicle is different from refueling a gasoline car. It involves managing a lithium-ion battery that powers the vehicle, and the way you charge can affect its longevity and performance. Let’s delve into the basics of charging to 80% or 90%:

Charging to 80%

Charging to 80% of your EV’s battery capacity is a conservative approach. It’s a method aimed at prolonging the battery’s lifespan and maintaining optimal performance.

By not charging the battery to its full capacity, you reduce stress on the battery cells, which can slow down degradation over time.


  • Reduced wear and tear on the battery
  • Longer battery life
  • Enhanced overall battery health


  • Limited driving range compared to a full charge
  • May not be suitable for long trips without multiple charging stops

Charging to 90%

Charging to 90% provides you with more driving range compared to an 80% charge. It’s a convenient option when you need that extra buffer for longer journeys.

However, it may have some impact on the battery’s long-term health due to the increased stress on the cells.


  • Extended driving range
  • More flexibility for longer trips
  • Convenient for regular use


  • Potential for increased battery degradation over time

Factors to Consider

Now that you understand the basics of charging to 80% or 90%, let’s explore the factors you should consider when deciding which charging level is right for you:

Daily Usage: Consider your daily driving needs. If you mainly use your EV for short commutes and have easy access to charging, charging to 80% may be sufficient. However, if you frequently take longer trips, charging to 90% might be a more practical choice.

Battery Health Concerns: If preserving your battery’s health for the long term is a top priority, opt for 80% charging. This is especially important if you plan to keep your EV for many years.

Longer Trips: If you often embark on long journeys, charging to 90% can provide you with extra peace of mind, but be aware that it may impact the battery’s long-term durability. In such cases, it’s important to balance convenience with battery preservation.

Charging Infrastructure: Your access to charging stations and the convenience of charging away from home can also influence your decision. If you can easily charge during the day, you might lean towards 80%. However, if charging options are limited, you may choose to go up to 90% for added range.

Manufacturer Recommendations: Some EV manufacturers provide guidance on how to best manage your battery. It’s a good idea to consult your vehicle’s manual or contact the manufacturer for specific advice.

Important: EV battery replacement can cost $1000s. To avoid high-voltage battery replacement, there are some things you can do. Read this article to find out the 10 best ways to maximize EV battery life and save tons of money!


The decision of whether to charge your EV to 80% or 90% depends on your individual circumstances and priorities. If you want to maximize the longevity of your battery, especially if you’re not planning on long trips, charging to 80% is a prudent choice.

On the other hand, if you frequently need more range for your daily drives or extended journeys, charging to 90% may be more practical.

Ultimately, the key to balancing battery preservation with convenience is to be flexible in your charging habits. You can choose to charge to 80% for daily use and increase to 90% when you anticipate a longer trip.

By considering your daily routine, battery health concerns, and manufacturer recommendations, you can find the charging strategy that best suits your EV ownership experience.

Remember, the goal is to enjoy your electric vehicle while ensuring the battery remains healthy for the long run.
