New electric vehicles come with warranties that can cover batteries for up to eight years, or 100,000 miles. A warranty, however, is intended to provide a guideline and not a guarantee about the battery’s lifetime. According to the National Renewable Energy Laboratory, new EV batteries might last twice as long.

According to the U.S. Department of Energy, there is no proven track record that can fully evaluate battery life in the burgeoning EV marketplace. According to the U.S. Department of Energy, more than 100 EV models were introduced in 2016. This means that most are still years away their useful lives. It is unknown how they will perform over the next few years.

How to prolong the life of your EV battery

All-electric vehicles are powered by lithium-ion batteries. This is the same technology used in laptops and smartphones. This battery is fast to charge, holds a charge, and can be used in cars due to its weight and price.

The maximum power it can retain when fully charged decreases over time just like a smartphone’s battery. A standard use may result in a charge holding 70% less than it did when new, but the warranty will still apply. The details of the warranty may differ from one EV.

According to car manufacturers, the following practices can prolong the life of your battery.

  • Do not charge your battery to 100%. Keep it between 20% and 90%, unless you have an extra range.

  • Pay attention to the climate. Extreme temperatures can reduce your battery’s lifespan. Preconditioning is a way to prevent this from happening. It regulates the temperature of the battery before it can be used. Preconditioning is something that may be familiar to anyone who has heated up a gasoline engine before driving. However, it can sometimes take over an hour.

An electric car battery replacement cost usually runs between $4,000 to $20,000. The large cost range is due to the different sizes of batteries, which can be costly. However, smaller batteries can cost thousands. A new EV can be purchased for as little as $27,000. However, it may not be the best choice in all cases.
