car battery
Under-hood power source
A car battery is a rechargeable battery that provides electrical current to start a vehicle's engine and power its electrical systems.
Most are lead-acid batteries, typically lasting three to five years.
The car won't start—I think the battery's dead.
Jumper cables connect a dead battery to a working one for a jump start.
