Is a Car Battery 12V or 24V?

[DeJoel]

Whether a car uses a 24V or 12V battery depends on the vehicle's battery and electrical configuration. Most small and medium-sized cars predominantly use 12V batteries. Here is relevant information about car batteries: 1. Differences between 24V and 12V batteries: A 24V battery has twice the voltage of a 12V battery. If the ampere-hour (AH) rating is the same, a 24V battery is approximately twice as large in size compared to a 12V battery. 2. Battery maintenance methods: Avoid parking the car in open parking lots for extended periods. If long-term parking is necessary, remove and take the battery with you to prevent freezing damage.
