Why Are Car Batteries So Heavy? Factors That Affect Weight

Battery Size

The main factor is the size of the battery. If it is a larger battery and requires more capability, it will also contain more electrolytes, plates, and other internal parts. As these parts increase, so does the weight of the battery, unless it is a lithium-ion counterpart.

Type of Car Engine/Type of Vehicle

Obviously, a motorcycle will require a smaller battery than your heavy-duty pickup truck. Because of this, there are different battery types, each with its own weight. Typically, the larger the battery becomes, the more it will weigh. However, this isn’t the case with the lithium-ion batteries, which are naturally lightweight.
