Are Car Batteries 12V or 24V?

[MacFrank]

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. Large heavy-duty trucks may have either 12V or 24V battery configurations, with the 24V setup typically consisting of two 12V batteries connected in series. Below is some relevant information about car batteries: 1. Difference 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 as a 12V battery. 2. Battery maintenance methods: Avoid parking the car in open parking areas for extended periods. If long-term parking is necessary, remove and take the battery with you to prevent freezing damage.
