How Long Should a Hybrid Battery Last?

Hybrids are fantastic cars for drivers who want to save on gas. But some drivers encounter an unpleasant surprise when they realize their battery needs to be replaced just a few years later. While Toyota states that their hybrid auto battery used in the Prius has an expected lifespan of about 10 years, that number could be very different for each driver, and here’s why.

Vehicle Usage

Hybrid Vehicle

The first factor to consider is how often the car is driven. According to Toyota, the battery pack in a hybrid Toyota is warrantied for 10 years or 150,000 miles in California and 8 years or 100,000 miles in all other states. This is great news for those who drive their vehicle a short distance to and from work every day. They will likely get closer to that ten-year mark than a full-time Uber driver. Ultimately, the more the battery is used, the shorter its lifespan will probably be.

Service and Maintenance

Another factor that affects battery life in a hybrid is how often the vehicle is serviced and how well it’s maintained. If the driver doesn’t take great care of the engine, for example, the battery will pick up the extra slack. Hybrids are built to last, but unfortunately, this means some drivers neglect important maintenance routines. These drivers will likely wear down their battery life faster than someone who takes their vehicle in for regular tune-ups and maintenance.

Battery Balance

A typical Prius battery pack has 28 individual cells, with each cell powering a certain amount of the battery. Over time, the capacity of each cell deteriorates, but not every cell deteriorates at the same rate. This means that battery power is unbalanced, so the battery will drain faster than if all cells were balanced.
