GREEN BEAN GUIDE
Consider Replacing Both At The Same Time
The 12-volt battery is the initial energy source when starting a hybrid vehicle. It also provides power to all of the computers, the lights, the locks, windows, and other auxiliary functions of the vehicle. When your hybrid battery starts to malfunction, the 12-volt battery gets stressed, causing it to lose power. When the 12-volt battery loses power, it can cause symptoms like flashing lights, dashboard not working, key fob issues, the vehicle will not turn off, and more. After replacing the hybrid battery, the vehicle may appear fine for a few days and then not start due to a 12-volt battery issue. Replacing the 12-volt battery along with your hybrid battery is a good step toward ensuring that all your electrical systems are functioning properly.
