Do I Need a New Battery For My Hybrid Car? Signs To Look For

March 28, 2024

Wondering if your hybrid car needs a new battery? Here are signs you should look for. Hybrid vehicles offer a blend of gasoline and electric power, but their batteries can wear out over time. Here's how to tell if it's time for a replacement without breaking a sweat.

Hybrid Car Batteries

Before we get to the signs, it's essential to understand hybrid car batteries. Unlike traditional vehicles, hybrids rely on both gasoline engines and electric motors. The battery pack is the heart of the hybrid system, storing and supplying electricity to the electric motor. Typically, hybrid batteries are designed to last for several years, but like any other component, they can degrade over time.

Signs That Your Hybrid Car Battery Needs Replacement:

Decreased Fuel Efficiency

One of the telltale signs of a failing hybrid battery is a noticeable drop in fuel efficiency. If you find yourself making more frequent trips to the gas station despite maintaining consistent driving habits, this could indicate a problem with the battery.

Reduced Performance

A deteriorating hybrid battery can also lead to diminished performance. You may notice sluggish acceleration or a lack of power when driving uphill. These symptoms can be attributed to the battery's inability to supply sufficient electricity to the electric motor.

Increased Engine Running Time

Since hybrid vehicles utilize electric power at lower speeds, a malfunctioning battery may cause the gasoline engine to run more frequently than usual. If you observe the engine running longer than it should during typical driving conditions, it could signify battery issues.

Warning Lights

Modern hybrid cars are equipped with onboard diagnostics systems that monitor various components, including the battery. If the system detects a problem with the battery, a warning light will be lit on the dashboard. Ignoring these warning lights can lead to further damage and costly repairs down the line.

Age of the Vehicle

Finally, consider the age of your hybrid car. Most hybrid batteries come with a warranty ranging from 8 to 10 years or 100,000 to 150,000 miles, whichever comes first. If your vehicle is approaching the end of its warranty period, it's prudent to keep a closer eye on the battery's performance.

Benefits of Replacing Your Hybrid Car Battery

Replacing your hybrid car battery can significantly improve fuel efficiency and overall performance. A new battery ensures optimal energy storage and delivery, resulting in smoother acceleration and enhanced driving experience. Moreover, a fresh battery can extend the lifespan of your vehicle and reduce the risk of unexpected breakdowns, providing peace of mind on the road.

How long do hybrid car batteries typically last?

While it's technically possible to replace a hybrid car battery yourself, it's highly recommended to seek professional assistance due to the complexity and safety considerations involved.

When it comes to wheel safety, lug nuts don’t always get the attention they deserve. These critical fasteners are what keep your wheels securely attached to your car, and they need to be tightened to a very specific level of force—known as torque. Get it wrong, and you're risking more than just a loose wheel.

It’s difficult to drive anywhere in the Bay Area and not see a lot of Subaru vehicles. Whether it’s the Subaru Crosstrek, WRX, Outback, Forester, or Ascend, Subaru vehicles are everywhere. At Toole’s Garage we are big Subaru fans. Subaru vehicles are built for the great outdoors, and of course California provides plenty of opportunity for on-road and off-road adventures. All wheel drive (AWD) comes standard on many Subaru models, and can provide consistent traction whether you are on a muddy road, or skiing in the Sierras. If a roof rack did not come standard with your model, it’s easy to add. And of course, interior space is pretty generous, especially if you drive an Outback or Ascent – you can stow plenty of camping and hiking gear. At Toole’s Garage we can provide your Subaru with the maintenance it needs to provide you with a reliable ride – wherever your adventures take you. We highly recommend regular oil change – it not only improves performance and extends engine life, but it also allows us to inspect various sub-systems of your Subaru to catch any impending problems (for example, older Subaru models were prone to oil leaks). And if a long summer trip is in the cards, we definitely suggest bringing it in for a checkup. Being a full service auto repair shop, Toole’s Garage can provide your Subaru with routine maintenance services, diagnostics, as well as major repairs. If your Subaru needs new brake pads, has the check engine light “on”, suffers from transmission problems, or needs major engine repairs – we can make your vehicle healthy again. Whether you have owned your Subaru for a long time, or have recently acquired one, bring it to our San Carlos auto repair shop – we will keep your vehicle in peak condition. Call us to make an appointment, or you can make an appointment online, on our website.
