How Long Does A Hybrid Battery Last?

One of the benefits of switching from ICE vehicles to hybrid vehicles is that it’ll save you thousands of dollars each year. It’ll halt constant visits to gas stations.

You’ll only spend half the amount of money on gas compared to your neighbors with ICE-powered vehicles. Though, you’ll have to pay something either to repair or replace the hybrid battery.

Hybrid batteries consist of several individual cells. Like every other battery, they have a shelf life, which means they will eventually lose power capacity. So, how long does a hybrid battery last in a car, anyway?

Most hybrid vehicle manufacturers give 80,000 to 100,000 miles or eight to ten years warranty on their hybrid batteries. Whichever comes first. Most consumers have also reported that with the right basic maintenance on the battery, it’ll last up to 150,000 miles. Few others have stated that it goes beyond 150,000 miles.

So, if you were asking how long does a Toyota hybrid battery last or how long does a Lexus hybrid battery last, both manufacturers give 800,000 to 100,000 miles.

“What Can Affect Your Hybrid Battery’s Life?”

Like many system components of a car, several factors affect a hybrid battery’s lifespan. How frequently you charge, your service routine, where you live, and even how you drive affect the life of your hybrid battery.

Lack of maintenance

Every vehicle needs regularly scheduled maintenance to keep running smoothly. The electric motor and the internal combustion engine in your hybrid vehicle are somewhat interdependent to run perfectly. So, if anything goes wrong with one, it’ll affect the optimal operation of the other.

Therefore, always check the battery state during every vehicle service and other maintenance. If any of the individual cells in the battery are bad, condition the battery to prolong its lifespan. To ignore checking the health of the battery at service intervals may shorten the life of the battery.

Not following the manufacturer’s charging guidelines.

The way you charge the battery plays a big role here. Always follow the manufacturer’s charging guidelines to maximize the lifespan of the battery.

The manufacturer’s instructions represent the manufacturer in print. Additionally, do not allow your battery to run down flat and do not charge it fully from zero. Avoid driving on an extremely low battery.

Extreme temperatures

Extreme weather conditions and fluctuations can be detrimental to the battery. Hybrid and electric car batteries are engineered to work within a specific range of temperatures. Traveling in extreme weather conditions for extended periods can be a catastrophe to the battery. Check this article if you’re asking how long the electric vehicle battery last.

Although, in hot weather conditions, an auxiliary hybrid battery fan helps to cool the battery module. Therefore, keep the auxiliary fan clean to have adequate cool air blowing in.

How To Increase The Lifespan Of Hybrid Car Battery

At this point, you won’t be asking, ‘how long does a hybrid battery last in Toyota and other vehicle models?’ Indeed, these batteries last long enough. But do you want to make them last even longer?

Hybrid vehicles run on both electric motors and internal combustion engines. Both the electric motor and the internal combustion engines have to work in direct proportion for a hybrid vehicle to function as a fine-tuned machine. Poor internal combustion engine performance will put a load on the hybrid battery and drain it much faster.

Also, when the internal combustion engine components are functioning properly, the driver will have confidence in the wheel and not worry about vehicle maintenance. And if you ignore system components maintenance, the hybrid battery will try to compensate. This will drain the battery’s power. Follow these measures to extend the lifespan of your hybrid battery.

Regular maintenance

Always carry out regularly scheduled maintenance on your hybrid vehicle. Hybrid vehicles are strong. Toyota Prius, for instance, can run 180,000 kilometers without displaying any issues. But if you ignore regularly going for service maintenance, you’re ruining the hybrid battery.

Once you elapse the 80,000 miles warranty period, take the vehicle to the dealership to diagnose the battery. After that, keep inspecting the battery every 12 months.

Keep the auxiliary fan clean.

The auxiliary fan blows cool air to the battery to keep it cool, but over time, it becomes dirty and needs periodic cleaning.

As the fan blows cool air to the battery pack modules, it collects dust, which will block the air ducts and reduce the efficiency of the fan. Keeping the auxiliary fan clean will increase the lifespan of the hybrid car battery.

Conduct a hybrid battery test.

Some automotive garages electric and hybrid battery test services to find weak cells. They can revive these cells and make them 97% strength of the original capacity.

By doing so, you can restore a weak battery without digging a hole in your pocket. This will only be possible if you detect and replace the weak cells on time.

How Do You Know When Your Hybrid Battery Needs To Be Replaced?

Whatever reason you’re switching to hybrid, whether it is to get more miles per gallon or for the benefits of the environment, it’s important to note that the efficiency of the vehicle depends on the battery.

These batteries last a minimum of 80,000 miles or eight years. However, Toyota claims that with proper maintenance, the battery will last the life of the car. Like every vehicle component, the hybrid battery can develop a fault. Hence, it’s important to know when your hybrid battery needs replacement.

Fewer miles per gallon

As an experienced and cost-effective driver, you should always keep an eye on your mileage. If you notice that you’re visiting gas stations more constantly than normal, check your hybrid battery life.

It could mean the engine is running more on the internal combustion engine. What could be the cost? It shows the battery is not charged to full capacity or not retaining electrical power as it used to.

State of charge

The vehicle projects a state of charge on the driver information screen. If you observe a significant display of the state-of-charge fluctuations on the information screen while driving, it shows there is an imminent problem.

The significant fluctuation means you have a failing hybrid battery or issues with the charging systems. Whatever the reasons are, visit your dealership to track the cause and fix it as soon as possible.

Charging problems

Every good battery should discharge at a predictable and steady rate. In any case, several factors affect the charging system of the battery, which plays a significant role in the overall health of the battery. If the charging system is undercharging or overcharging the battery, or the battery has a parasitic drain, it’ll decrease the lifespan of the battery.

Mechanical issues like bent pins, damaged wiring, and corrosion can be detrimental to the battery. If you charge the battery fully overnight and you notice a slow start in the morning, you have a charging system problem or a failing battery.

Erratic engine performance

If your internal combustion engine runs erratically, it shows your hybrid battery is dying. This is because the hybrid battery and the ICE work in direct proportion. An issue with one will affect the other.

If the internal combustion engine works more than it should or stalls randomly, consult a certified mechanic. However, several things can cause erratic idling. But, it is also a sign of a dying battery.

Strange noise

Constant noise from the auxiliary fan shows that the fan is running longer than it should. This happens when the battery is running hot and the fan tries to compensate by working steadily to cool it.

A hot hybrid battery indicates battery issues, which is not good for the nearby system components. Track the culprit and fix it as soon as possible before things get worse.

Whether the vehicle displays a warning light on the driver information screen or you observe the above signs, seek professional help.

“Why Do Toyota Hybrid Batteries Last So Long?”

In the last decade, consumer reports conducted a test on 2001 Toyota Prius and identical 2002 Toyota Prius hybrid batteries. The 2002 Toyota Prius has covered over 200,000 miles, and the 2001 Toyota Prius has only 2,000 miles. The test confirms a little degradation in fuel economy and acceleration on the 2002 Prius hybrid battery with over 200,000 miles.

Consumer reports were amazed to discover that the high-mileage car still drives like a new vehicle. Aside from that, the vehicle is still running on the original transmission, engine, and even shock absorbers. This proves how strong Toyota hybrid batteries can be. So, if you were asking how long does the hybrid battery last in Prius, the test here should give you a clue.

The truth behind the longevity of the Toyota hybrid batteries is that they feature an efficient nickel-metal battery pack. They have a computer-controlled charge controller and battery management computer system that maintains an 80/20 battery rule.
