Whether you’re replacing a battery, calculating shipping costs, or comparing different models, knowing the weight of a car battery is essential. Car batteries come in a wide range of types and sizes, depending on the vehicle class, battery group standard, and application type (such as starting vs. deep-cycle, AGM vs. flooded, etc.).
Here we provide a comprehensive lookup table to answer the question: “How much does a car battery weigh?”
| Factor | Impact on Weight |
|---|---|
| Tipo de bateria | AGM > Flooded > EFB > Lithium |
| Group Size (e.g. 24F) | Bigger group = heavier battery |
| Application | Deep-cycle and dual-purpose batteries are heavier |
| Amplificadores de partida a frio (CCA) | Higher CCA usually = more lead = more weight |

AGM batteries are ~10–15% heavier than standard flooded batteries due to added materials and internal pressure regulation.
Lithium batteries can be 50–70% lighter than lead-acid batteries of similar capacity, ideal for weight-sensitive applications.
Battery weight is important for shipping (freight costs are calculated by kg or lbs) and for vehicles with space or payload limits.
The easiest way to estimate “how much does a car battery weigh” is by checking your vehicle’s battery group size, then referring to a standardized chart like the one above. If you’re still unsure, consult your vehicle owner’s manual or battery label.
