Once the engine is on, the alternator takes over by recharging the battery and powering the cars electronics.

• Reserve Capacity (RC): How long the battery can provide power if the alternator fails.

• Voltage: Most car batteries are 12 volts, suitable for standard vehicles.

• Group Size: Indicates the physical dimensions and terminal locations. Always choose the right group size for your vehicle.
