  • Significant reduction in fuel economy 

 

What if the first common bad hybrid battery symptom is a significant reduction in your fuel economy. If you notice that your vehicle is not giving you the expected gas mileage, your vehicle's battery is most likely dying.

Thus, once your vehicle realizes that the battery will die, it will switch automatically to use the fuel and thoughts. You'll notice a significant reduction in your vehicle's fuel economy.

How do you test a hybrid battery?

Now, if you have noticed any of the mentioned symptoms of a bad hybrid battery, it is recommended that you do your homework and check whether your battery requires professional mechanic attention or not.

This is because professional mechanics will take time and money to do their tests, and the patient might not be related to the battery itself. Thus, it might be worth doing what's known as stress testing.

What stress testing means is that you challenge your battery and use a certain scanning tool to check whether any problem is coming from your battery or not.

To do so, you can visit any repair shop and ask them to provide you with a scanning tool that is suitable for hybrid batteries. Some of those scanning tools are the TechStream that Toyota uses or some aftermarket ones to check, like the Snap-on or the Matco.

Those tools are not like the OBD2 tools that you use for checking any standard vehicle errors. They are specifically used to check the hybrid battery capacity.

The test itself is not very complicated, and anyone with very minimal mechanical skillsets can do it.

Here's all you need to do to perform a stress test on your hybrid battery:

  1. Find an empty area where you can perform the test. An ideal place would be an empty area safe in the back of the street or anywhere where people are not around.
  2. Use the scanning tool to scan all current errors or perform what's known as diagnostic trouble codes scanning.
  3. Then, you need to move on to the live data collection process, which means that you need to start your hybrid battery and have your vehicle exploits up to 30 mph.
  4. After that, drop to neutral but not to a complete stop.
  5. You need to repeat the process at least five times.
  6. Once you finish repeating the five times, your scanning tool will tell you your hybrid vehicle's battery's overall status.
  7. Once you get the results, it's then your decision to check whether it's worth visiting a personal mechanic or not. If you notice that the battery has significant problems and requires replacements, you have no other choice. Otherwise, you need to check any other culprits causing the bad hybrid battery symptoms you've noticed.

Can I hybrid battery run on fuel only?

Yes, that is the backup situation. When your hybrid battery goes bad, your vehicle will switch to the fuel.

However, keep in mind that the other way is not possible. For example, if you are looking to run your vehicle with electricity only, this cannot happen.

According to Toyota help discussion, hybrid vehicles are designed to run on hybrid batteries only if there is enough fuel in the tank. Thus, if your tank doesn't have any fuel, your hybrid battery will not engage, and the vehicle will not run.

Otherwise, it is not recommended to spend this money on your vehicle.
