How to Tell if Your Prius Battery is Dying

How to Charge a Prius Battery

Driving a hybrid vehicle can be beneficial for your budget and beneficial for the environment, but if you have not driven one of these vehicles before, it can be overwhelming to learn all about these new features. When it comes to your vehicle’s battery, how are you supposed to know if the battery is dying? You probably recognize some signs to look for when it comes to a traditional engine but what are the warning signs of a dying hybrid engine? Let’s take a look at some of the warning signs you can keep an eye out for when it comes to a hybrid Prius battery that needs some assistance.

I’m Getting Lower Miles Per Gallon, Is There a Problem?

Most people keep a close eye on their miles per gallon number, and this is a great place to start. Of course, some other parts of your Prius can affect these numbers, whether it be your tire pressure or the weather outside, but a constantly changing MPG number can indicate that your battery isn’t charging to its full capacity anymore. The decrease in your MPG can occur during acceleration as well but it should never dip below a reading of ten MPG. If it does, battery failure is likely to happen in the immediate future.

The Current State of Charge

If you suspect there is a problem with your Prius battery, you can take a look at your state of charge readings. If you find that some significant fluctuations are going on while your vehicle is running, this is a universal sign of a hybrid battery problem. Sometimes it can be related to the charging system of your car, but that is not usually the case with SOC readings. If you are fluctuating from purple to green and back again, you may want to keep an eye on this or have your battery looked at.

What If My Engine is Running Erratically?

If you find that your internal combustion engine or ICE is running erratically, this isn’t normal and could be due to a dying Prius battery. You may see it stops randomly or runs longer than usual. If this happens frequently, then it’s time to look into battery issues. There could be some other concerns to address but testing the battery is usually the first thing to be done when this type of problem is going on.

Mileage Readings Are Off The Charts

If you find that your Prius is ranking up when it comes to mileage, then you may want to keep an eye on your battery. Each battery is supposed to last the entire time that you own your Prius. If your vehicle is getting older and you still have your original battery, this is something to watch. Nearing 200,000 miles along with some other battery end of life signs means you might want to start planning for your battery failing.

Owning a hybrid vehicle brings a new set of maintenance and repair issues that you need to address during the time that you own your car.
