2 Answers
The battery model for the Corolla is 55d23l. The functions of the battery are: 1. To supply power to the engine starting system, ignition system, and the vehicle; 2. To power the vehicle's electrical equipment when the engine is off or idling at low speed; 3. To mitigate impact voltage in the electrical system and protect the vehicle's electronic devices. The maintenance methods for the battery include: 1. Avoid overusing the battery; 2. Regularly clean the positive and negative terminals of the battery; 3. Periodically check the vent holes on the cover of non-maintenance-free batteries to prevent clogging; 4. Avoid low battery water levels; 5. When parking for an extended period, start the vehicle once a week to charge the battery.
I've been repairing cars since the 90s, and the standard battery model for the Corolla is 55B24R, with a capacity of around 45Ah, suitable for models from around 2000 to 2020. Newer models like the 2023 version might use 46B24R, which is slightly larger in size. The model must match the battery box, otherwise, installation can be troublesome or result in slow starts. When changing the battery, first check the cold cranking amps (CCA), commonly 360 amps, and brands like Panasonic or Bosch are recommended to prevent leakage. Before doing it yourself, make sure to disconnect the negative terminal to avoid short-circuit sparks. If the car is not used for a long time, start the engine once a month to charge the battery and extend its lifespan—don't wait until winter when it won't start to replace it. This experience has saved me a lot of money.
