A 12-volt battery replacement at the same time as your hybrid battery is the best practice.

If your 12-volt battery is having issues, it will severely impact your hybrid battery. You should always have both batteries checked!

Why a 12-Volt Battery Replacement is Important:

  1. The 12-volt battery (see where it’s located in a Toyota Prius) plays a critical role in hybrid vehicles, serving as the primary energy source during the starting process. 
  2. It serves as the power supplier for a wide range of essential functions, encompassing everything from computers and lights to locks, windows, and various auxiliary components.
  3. As the 12-volt battery ages, it can lead to multiple issues, including no start scenarios, flickering or loss of lights, and false data for the computers. This can cause hybrid battery failure through over and undercharging the hybrid battery.

If you only replace the hybrid battery, and the 12-volt is bad, you may encounter a frustrating situation. Your vehicle will seem to function normally for a few days, only to suddenly refuse to start because the 12-volt battery failed. By replacing the hybrid battery and the 12-volt, you can avoid issues from an aging or deteriorating 12-volt battery. 

Since the 12-volt battery is responsible for powering essential systems beyond just the starting process, it is crucial to maintain its optimal functionality to prevent unexpected failures. This can include premature failure of your hybrid battery replacement and other electrical components.

By taking this proactive step, hybrid vehicle owners can enjoy a reliable and uninterrupted driving experience.
