What is the size of the battery used in the Toyota Corolla?
3 Answers
The battery used in the Toyota Corolla is 23 centimeters. The functions of the battery include: 1. Providing power to the car's starter and ignition system; 2. Supplying a stable DC power source for the car's electrical appliances. The Toyota Corolla is a compact car with the following body dimensions: length 4635 mm, width 1780 mm, height 1455 mm, wheelbase 2700 mm, and a fuel tank capacity of 50 liters. The Toyota Corolla is equipped with a 1.2T turbocharged engine, delivering a maximum power of 85 kW at 5200-5600 rpm and a maximum torque of 185 Nm, paired with a CVT continuously variable transmission.
As an ordinary car owner who has driven several Corollas, the battery is generally 12-volt 45Ah or 55Ah, depending on the model year. For example, my older model had a 45Ah battery, while newer models may have upgraded to 55Ah for better durability. Daily use shows that battery size directly affects starting performance, especially in cold winter temperatures—smaller capacity batteries may struggle. When replacing the battery, always check the label under the hood; the Cold Cranking Amps (CCA) should ideally match the original specifications, ranging between 400 to 500 amps. Maintenance tips include regularly cleaning the battery terminals to prevent corrosion and using a multimeter to ensure the voltage doesn’t drop below 12.4 volts. Frequent short trips can lead to insufficient charging and faster aging, so remember to turn off power-consuming devices when parked. A good battery can last three to four years without issues—avoid cheap, low-quality options to prevent breakdowns on the road.
In workshop experience, the standard battery specification for a Corolla is a 12-volt 45Ah or 55Ah battery, with the key factor being the cold cranking amps (CCA), typically around 420A. The battery capacity (Ah) determines the power reserve—too small and there won't be enough power for starting, too large and it won't fit in the space. When replacing, it's recommended to retain the original size and keep the CCA value close, opting for OEM or reputable brands for better reliability. Regular voltage checks are crucial; a healthy battery should read between 12.6 to 12.8 volts. Below 12.4 volts indicates it's nearing the end of its life and should be replaced. Maintenance focuses on keeping terminals clean to prevent oxidation, which affects conductivity, and avoiding prolonged parking without charging. In cold weather, batteries with higher CCA values perform better, reducing the risk of failure.
