What Happens When My Hybrid Battery Dies?

Rising fuel costs are a cause of concern for many people out there. We need cars to commute to work and run errands, but with the way gas goes, it might be too expensive. Many people have gravitated towards more fuel-efficient cars and hybrids to help save money.

Hybrids are great vehicles to help families save some money and still get the power they need. These cars generally work off of two different batteries: there is the normal car battery that you expect and a secondary battery that handles the electric motor that helps you save fuel. Just like any other car, these batteries can eventually wear out and die. What do you do if your hybrid battery dies, but the battery for the gas engine still lives? Is it drivable?

Can You Drive with a Dead Hybrid Battery?

There are a few different ways that a hybrid car can be set up and that configuration is important. The Prius works off of a parallel system meaning that the gas and electric engines work beside each other. It picks up some of the slack from the smaller gas engine and helps the car accelerate and decelerate. If that battery fails, then you could still drive the Prius, but it will be weaker and a lot less smooth. While it is drivable, we recommend getting the batter fixed as soon as possible.

Other hybrid systems that require a 12-volt battery might not work if the hybrid battery dies. Even if your car does start, you run the risk of your car losing power or dying on the road. It is best to take your car in to the dealership the second you notice something wrong. In addition to the warning lights, you can look out for poor gas mileage, sluggish performance, and slow acceleration.
