How Do I Know My Hybrid Car Battery Is Failing?

By Bill DeBoer on Jan 28, 2018 1:52:00 PM

The average life of a car battery is different for a hybrid car.

Today, there are more hybrid carson the road, which means there are also more problems the average car owner needs to learn about and potentially deal with. For instance, the battery found in your hybrid vehicle is different from your typical car battery, which means the average life of a car battery may not be the same. However, you do still need to know when it’s time to get a new hybrid car battery before it is too late.


The average life of a car battery is different for a hybrid car.Reduced Fuel Mileage

For those who have owned a hybrid vehicle since it was new, it can often be easier to see the more subtle changes to your vehicle’s performance. One of the first things you will notice is your fuel mileage will begin to decrease from what it once was. The reason for this is because the EV mode will be on for shorter periods of time less frequently, which means your vehicle will be running on gas more often than the battery power.

Negative Battery Re-Calibration

Most people aren’t familiar with this term, but they are aware of the concept. What negative battery re-calibration refers to is when you plug your car in with a partially full battery and upon returning after a day or two, the battery is empty, rather than full. You will head out to your garage thinking you will have a full battery to get where you need to go, only to find it has been drained.

A hybrid car battery requires different care than traditional batteries.

Negative Recalibration While Driving

It can be a major disappointment to go out to your garage and find out there is no charge to your car battery. However, if your battery is losing charge while you are driving, this can be an indication it is beginning to fail. In addition to the battery gauge, you will also find the engine revs more often because the car will attempt to refill the battery any way it can. This is the final indication before the battery warning light illuminates.

What Can Car Dealerships in Sussex Do?

Once you reach the average life of a car battery, especially a hybrid battery, it’s important to take your car to the car dealerships in Sussex that handle these matters. The good news is dealers familiar with the hybrid vehicles may not have to replace the battery entirely. In fact, they can typically recondition the battery back to a healthy state so it will continue to charge as it was intended and restore your gas mileage to normal. This is an ongoing service that is required approximately every three to six months to ensure your battery lasts as long as possible before replacement.

A hybrid car battery is much different than your typical car battery. These batteries can actually be reconditioned as part of the maintenance requirements for your car, helping you keep your hybrid car in good operating condition for as long as possible.
