Is a Car Battery 12V or 24V?

[RyanFitz]

Car batteries are typically 12V; multi-cylinder diesel engines and single-cylinder diesel engines above 25 horsepower usually use 24V battery voltage. The differences between 12V and 24V batteries are as follows: Starting Performance and Versatility Differences: 12V batteries offer better versatility but poorer starting performance. 24V batteries perform well in both versatility and starting capabilities. Application in Vehicle Models Differs: 12V batteries are easier to identify. Light trucks equipped with a single battery usually have a 12V voltage, commonly used in entry-level light trucks and most mini trucks and small trucks. Some light trucks with hydraulic brakes also use 12V batteries. 24V is currently the mainstream battery voltage choice for light trucks. Cost Differences: The obvious advantage of 12V batteries is their lower cost, including purchase and maintenance/replacement costs. 24V batteries are correspondingly more expensive due to the use of two batteries. Different Adaptability: 12V batteries are more adaptable to electronic products, as electronic components used in passenger vehicles can be directly applied.
