A standard car battery for most gasoline-powered passenger vehicles typically weighs between 30 to 50 pounds (14 to 23 kg). The exact weight depends primarily on the battery's size, which is indicated by its Group Size, and its internal construction. Larger vehicles like trucks and SUVs require batteries with more power and often have heavier batteries, sometimes exceeding 50 pounds.
The weight is largely due to the lead plates and sulfuric acid electrolyte inside. A traditional flooded lead-acid battery contains these heavy components. While Absorbent Glass Mat (AGM) batteries, a common upgrade, are often slightly heavier than their flooded counterparts of the same group size due to their denser internal structure.
Here’s a quick reference for some common battery group sizes and their typical weights:
| Battery Group Size | Vehicle Type Example | Typical Weight Range (lbs) | Typical Weight Range (kg) |
|---|
| 48 (H6) | European sedans, some SUVs | 40 - 50 lbs | 18 - 23 kg |
| 35 | Common Japanese & American cars | 38 - 48 lbs | 17 - 22 kg |
| 24F (24) | Common Honda, Toyota, Nissan | 39 - 46 lbs | 18 - 21 kg |
| 34 | Many Chrysler, Dodge, Jeep models | 43 - 53 lbs | 20 - 24 kg |
| 65 | Large American sedans, trucks | 45 - 55 lbs | 20 - 25 kg |
| 75 | Common GM vehicles | 35 - 45 lbs | 16 - 20 kg |
| 94R | Many Ford vehicles | 45 - 52 lbs | 20 - 24 kg |
Knowing the weight is practical for two reasons. First, for safety when handling or transporting a battery—always lift with your legs, not your back. Second, if you're considering an upgrade, remember that an AGM battery might add a few extra pounds. Always check your owner's manual or the label on your old battery for the correct group size before purchasing a replacement.
