When considering changing a Toyota Prius battery you should first understand what kind of life expectancy these have. For instance, a factory Toyota Prius battery can run for about 10 to 12 years or 150.000 miles. After that their efficiency drops to about 80%. Sure, you can still get a few good years out of them after that, but you might not get the same speed or mileage you once got. That’s because the elements inside the battery deteriorate. Also, a batteries’ lifespan is influenced by a variety of factors such as climate, driving style and how one takes care of the car itself.
Replacing a Toyota Pius battery can be a very good decision, especially after the original one has been used for more than 10 years. But before rushing out to buy a new battery, you should first check for the signs that the old one isn’t up to the task anymore. You should always look for signs like dim headlights or headlights that stay on even after the car has stopped. That means that there is residual charge in the circuit and that it is draining the power from the battery. Also, make sure that all the lights on the dashboard are working. If they are not or if they are flickering in any way, you should do the right thing and buy and install a new battery.
