Factors Determining your Tesla’s Battery Life

1. Tesla Model

Different Tesla models have different batteries. These batteries have a unique battery type, size, and capacity.

Battery Cell Chemistry

Tesla mainly has two major categories of electric vehicles, which include standard range electric vehicles and long-range electric vehicles.

Tesla Started with Nickel Batteries

Initially, Tesla was manufacturing nickel-cobalt batteries for its electric vehicles. These batteries were relatively less efficient than lithium-ion batteries. They offered shorter ranges.

Due to their lower voltage, the batteries had lower capacities and offered lesser power. As a result, the nickel batteries do not last too long.

Nickel batteries allow a Tesla battery a lifespan of almost 100,000miles. This is considerably lower than what lithium-ion batteries offer.

Tesla Sifted to Lithium-ion Batteries

Tesla had shifted to making Lithium-ion batteries in the production plant in Shanghai, China. These lithium-ion powered Tesla cars were sold in China, Asia, and some areas of Europe.

In October 2021, Tesla decided to shift to lithium-ion batteries in all its standard-range vehicles. Some long-range models like the Tesla Roadster is also now lithium powered.

Tesla itself has explained how lithium-ion batteries are better than nickel or lead-acid alternatives. Lithium-ion batteries are specifically designed to have improved capacities and lifespans.

These batteries optimize energy, giving a Tesla high range and longer battery life per charge.

In 2019, Elon Musk claimed that a lithium-ion Tesla battery’s lifespan is 300,000-500,000 miles. This would equate to almost 1500 charging cycles.

The Tesla Model S, which has a lithium-ion battery, has a range of 752miles per charge. This is one of the highest ranges ever to be offered in an electric car.

However, lithium-ion batteries are more sensitive to harsh conditions and extreme temperatures. This is why Tesla recommends regular care for these batteries.

In some electric vehicles, Tesla is still using a lead-acid battery. Lead-acid batteries offer lower lifespans and lower ranges.  However, lead-acid batteries are more tolerant to changing temperatures and have a lower cost.

Battery Size and Capacity

The amount of charge a battery can store shows its battery capacity. In order to store more charge for higher capacity, you need a bigger battery.

Every time, a Tesla battery is fully discharged, its capacity drops. This results in a reduction of the battery lifespan. The key point here is that the bigger a Tesla battery, the higher it’s capacity. Hence, the longer its lifespan.

Over the years, Tesla has worked tirelessly to keep improving its batteries’ size and range. In 2015, Tesla worked a lot on improving its battery capacity. The 60kWh battery was improved to a 70kWh battery capacity.

In the next year, Tesla had further improved the same battery to a 100kWh capacity. This meant better range, higher efficiency, and longer battery life.

Similarly, year by year, Tesla has been upgrading its batteries to hold more charge. This allows them to last longer.

Look at the table below to understand how size and capacity affect the battery life (range). The table shows the different Model S battery sizes, capacities, and ranges.

The range depicts the particular Tesla’s battery life per charge.

2. Driving Style

The battery life/charge of your Tesla’s battery also depends on how you drive your Tesla.

Total Weight

The heavier your Tesla model, the more battery charging it needs to keep going.

If your Tesla has numerous passengers and is carrying heavy luggage, your battery will have to exert more energy and work harder. This stress on the battery reduces the battery range. This consequently reduces the battery’s life.

Acceleration for Long Periods of Time

Driving at high speeds, and changing accelerations for long periods is bad. It uses up the Tesla’s battery power quickly. As are a result, your Tesla would need a recharge much earlier than necessary.

Your Driving Route

Most Tesla vehicles now have lithium-ion batteries. These are sensitive batteries and heat up quickly. If Tesla has to go up many steep slopes, your battery life/charge would be reduced. 

In the long run, this negatively affects the total battery lifespan.

Extreme Temperatures

Lithium-ion batteries offer many benefits. However, their one down point is their sensitivity to temperature. 

Driving while the battery is too cold without letting it warm up would reduce the total battery life.

Similarly, driving in hot weather conditions would overheat your battery. If you do not allow it to rest and cool down, the total battery life/charge would also decrease.

Follow these tips to improve battery life and range in winter.

Humidity also affects the battery’s life. Driving in persistent rain for numerous days may corrode some battery connections. In the long run, it reduces the battery’s life per charge.

Driving against the direction of strong winds will also consume more battery power. As a result, the battery life per charge is reduced.

Short Trips and Frequent Brakes

Short trips would mean you have to restart your Tesla over and over again. Every time you restart your Tesla, more battery power is used.

In addition, hitting the brakes frequently also puts stress on the battery. As a result, shorter trips and frequent braking results in battery discharging quickly.

3. Battery Charging and Discharging

Charging and Discharging

Your charging routine always impacts the life of your electric vehicle.

Every time an electrical vehicle’s battery is fully discharged, its total capacity decreases. This leads to a reduction in battery life/charge as well as the total battery lifespan.

A Tesla has an ideal charging range. Elon Musk himself advises charging between 20%-90%. If your charge falls to these or even lower or higher than these levels respectively, the battery life drops.

Leaving the battery discharged for long periods of time also reduces battery life.

Charging During Extreme Temperatures

Charging the Tesla battery while the battery’s temperature is not normal is discouraged.

Charging Source

A Tesla has five main charging options.

  • The NEMA 5-15, 120 volts
  • The NEMA 14-50, 240 volts
  • The wall connector, 480 volts
  • Supercharging stations
  • Self-installed solar charging system

Different charging sources have different voltages. Each source offers a different charging duration.

Slow, low voltage charging is more suitable for your Tesla. Frequent use of high voltage supercharging stations negatively affects battery range and life.

4. Energy App

The built-in energy app allows you to analyze your driving patterns. It also provides guidance regarding charging needs and requirements.

Ignoring the assistance provided by the energy app could result in battery life reducing.
