Does your Prius really need to be checked for winter maintenance when it has operated just fine throughout this past summer and fall? You bet it does. Winter, with plummeting temperatures is when an unnoticed weak battery has the hardest time generating enough current to start an engine.
Battery Issues and Checks You Can Do Yourself
To be clear, we are talking primarily about the Prius 12-volt battery in the trunk that is used to provide power to the computer, relays, ECU, and assist in starting the vehicle.
The savings in money and stress knowing the health state of your battery before it dies on you cannot be overstated. For example, if you take the time to do a little battery cost comparison shopping, you will often find that the correct replacement battery for your car can often be cheaper through an online search for battery advertisements, rather than going with whatever an auto parts store happens to have on hand. Plus, you avoid becoming stranded and possibly incurring a tow charge bill that could be a tow scam and/or wind up damaging your car.
The Simplest Battery Health Check in Your Prius
Not unlike with your home flashlight, a low glowing bulb that draws very little current serves as a good test showing that all is not well electrically, with the most common cause being a drained battery.
The Better Battery Health Check
However, an even better check is using an inexpensive mechanic-recommended TopDon battery tester that costs roughly $40 and is remarkably simple to use to get the full picture of your car battery’s health.
That said, follow along with the host as he demonstrates both simple battery checks that could prevent you from becoming stranded on the road this winter and save you a lot of money.
