Hybrid vehicles have gained popularity for their fuel efficiency and environmentally friendly features. However, concerns about the longevity and replacement cost of hybrid batteries still linger in the minds of many potential buyers. In this article, we will explore the average lifespan of hybrid batteries and outline signs of a failing battery, so you know when to call Hybrid Battery 911 for a replacement.
How Long Do Hybrid Batteries Last?
On average, most hybrid vehicle manufacturers will provide initial warranties and state that a hybrid battery pack can last from 80,000 to 150,000 miles or 8-10 years on average. Some hybrid owners have reported batteries lasting well beyond 200,000 miles, but failure rates can vary depending on several factors, including driving habits and climate. Since the average car is on the road for 12.3 years, or about 166,000 miles, many hybrid vehicles will need a hybrid battery replaced once in the vehicle’s lifetime.
Why Do Hybrid Batteries Last So Long?
Hybrid batteries last longer than other car batteries that you may be more familiar with. For example, a car’s 12-Volt battery may only last 3-5 years. Hybrid vehicle batteries typically use advanced battery chemistries like nickel-metal hydride (NiMH) or lithium-ion (Li-ion), which are designed to provide higher energy density, better performance, and longer lifespan compared to traditional lead-acid 12-volt batteries. Many hybrid vehicles also incorporate battery management computer systems and computer-controlled charge controllers that prevent the battery charge from exceeding 80% or falling below 20%. But while hybrid vehicle batteries are designed to have longer lifespans than 12-volt batteries, they are still subject to eventual degradation over time.
Factors Affecting Hybrid Battery Life
Of course, every hybrid battery is different. Its environment, care, and various other factors can impact the lifespan of a hybrid battery, just like any other car component. Here are a few key factors to consider:
- Climate: Extreme temperatures can have a significant impact on the performance and lifespan of hybrid vehicle batteries. High temperatures can accelerate the degradation of the battery, while very low temperatures can reduce its efficiency and overall capacity. Therefore, operating a hybrid vehicle in extreme climates can shorten battery life.
- Driving Habits: The way a hybrid vehicle is driven can also affect the battery life. Aggressive driving behaviors, such as frequent rapid acceleration, can stress the battery and decrease its lifespan. Smooth and steady driving with gradual acceleration and deceleration is generally more beneficial for the battery's longevity. Breaking helps recharge the battery system in a process called regenerative braking, and low (slow) breaking is more efficient than hard (fast) breaking.
- Inactivity: Hybrid vehicles were designed to be driven, the battery degrades when sitting for long periods or driven infrequently. An idle battery (not being charged and depleted) will develop irreversible losses, leading to a shortened battery life. It’s recommended that a hybrid is driven at least 625 miles per month (7,000 annually).
- Maintenance: Proper maintenance of the hybrid vehicle, including routine check-ups, can contribute to preserving the battery life. Regularly scheduled maintenance, such as inspecting and cleaning the hybrid battery cooling fan and following the manufacturer's guidelines, can help optimize the performance and longevity of the battery.
- Age and Mileage: Over time, hybrid vehicle batteries may naturally degrade due to factors like age and accumulated mileage. As the battery ages, its capacity may decrease, reducing overall performance and shorter electric driving range.
Signs of a Failing Hybrid Battery
If you start to notice the following issues, it may be time to call Hybrid Battery 911 and schedule a hybrid battery replacement:
- Check System Indicator Light: Most hybrids have a dashboard indicator to alert the driver of a problem with the vehicle. However, you need to investigate more to see if it’s a hybrid battery problem. Using an OBD (on-board diagnostics) tool found at most vehicle sales or mechanic shops, you can get an error code that will specify the problem. With this code, one of our hybrid experts can diagnose the issue and offer the best solution.
- Poor Fuel Economy: If you notice a significant decrease in fuel efficiency, it could be a sign of a deteriorating battery.
- Rapid Battery Depletion: A battery that doesn't hold its charge and drains quickly may require replacement. Just like how your cell phone loses its ability to hold a charge over time, so does a hybrid battery.
- Decreased Driving Performance: A dying hybrid battery can affect the car's performance, leading to sluggish acceleration when you put your foot on the pedal.
- A Loud Fan Noise: Most hybrid batteries have their own battery cooling system. A failing battery will heat up and the fan will run louder and run continuously. The noise will be from the hybrid battery compartment, which is typically under or behind the back seat on many models.
What are my Hybrid Battery Replacement Options?
Hybrid Battery 911 offers several different replacement options, from remanufactured batteries to new ones. Typically, a remanufactured battery (Silver) can be purchased at one-third the price of a new battery, and this is usually the best choice for budget-conscious consumers or older vehicles. If your vehicle has more than five years of life left, we recommend one of our premium reconditioned (Gold) batteries or our new batteries (Platinum). Check out some options here.
If your hybrid battery needs replacement, we offer on-site battery replacement services, so you don’t need to be inconvenienced by taking your car to the dealership and waiting for hours. We’ll even take the old battery off your hands and recycle it! Don't let a failing battery slow you down – call Hybrid Battery 911 and get back on the road with confidence.
