Hybrid and EV 12-Volt Batteries: Yes, They Have One Too

Hybrids and electric vehicles have a big high-voltage battery that moves the car. They also have a regular 12-volt battery, much like a conventional car. It powers the computers, the door locks, the lights and the systems that connect the high-voltage battery to the rest of the car.

Why the small battery matters

If the 12-volt battery is too weak, the car may not start up at all, even though the large battery is fully charged. Drivers often see warning messages, a car that will not power on, or a key fob that stops working.

Different from a conventional battery

  • Many hybrids and EVs use AGM batteries, and some newer EVs use a small lithium 12-volt battery.
  • The battery is sometimes in the trunk or under a seat instead of under the hood.
  • Jump-starting and replacement often have specific procedures. Check the owner's manual and never connect anything to the high-voltage system.
