Many drivers are turning to electric cars lately, and it's estimated that electric cars will represent more than two-thirds of passenger car sales by 2040.
Despite their popularity, electric cars raise many questions and concerns. One of the biggest concerns is how long electric car batteries last. Generally, electric car batteries last as long as other cars. But just like phone or laptop batteries, they degrade over time. However, the cells will still provide at least 70% of their capacity after 200,000 miles, a mileage that few cars ever reach.

Battery Basics
Gasoline-powered cars use lead-acid batteries, but EVs have lithium-ion batteries. This is the same battery you'll find in your cell phone or laptop. Lithium-ion batteries have a higher energy density and can hold charge longer than standard car batteries.Lithium-ion batteries are lightweight and rechargeable, making them ideal for traveling vehicles. Batteries, like all other rechargeables, lose capacity with time, similar to our mobile devices, resulting in around 80% of the initial capacity after eight years of regular usage.
EV Batteries Life Expectancy
EV batteries in the US have a minimum warranty of eight years, or 100,000 miles. However, you should always read the warranty terms carefully. For example, KIA offers a ten-year battery pack warranty, while Hyundai provides lifetime coverage. Electric vehicle batteries typically last 10–20 years, but their lifespan can be shortened for a number of reasons.How to Make a Car Battery Last Longer
There are ways you can help conserve your battery's power and performance:- The life of a battery pack often depends on how well it is charged. You can extend battery life by charging the battery between 20% and 80% and trying not to let the charge fall below 50% too often. Exceeding this limit can increase the rate of battery degradation over time.
- Every electric vehicle battery will experience degradation, and this is inevitable. Manufacturers are trying everything possible to improve the battery life cycle and increase performance. So, whenever you buy an EV, you can rest assured. Your battery will provide smooth service for quite some time.
- Do not overcharge your EV batteries. Overcharging can cause chemical changes inside the battery, which can shorten your EV's battery life.
- Avoid exposing your car battery to high temperatures. Extreme cold or heat can negatively affect your car battery. Extreme temperatures can hasten the degradation of EV batteries.
