Car Battery Weight: How Much Does A Car Battery Weigh?
Cars and other vehicles come in various sizes and types, so do their batteries differ in size, type, chemistry, and a few more details, including, of course, their weight.
While car battery weight doesn't influence, at least not by much, performances of most passenger cars, SUVs, RVs, and similar, racing cars benefit from any weight savings. For this and many other reasons, people often ask how much does a car battery weigh.
Published: April 8, 2022.
Car Battery Types and BCI Group Sizes
The most common car battery types are lead-acid and lithium starting batteries, although vehicles with larger electric load (multimedia devices, winches, etc.) may have dual-purpose batteries.
Also, RV house batteries are almost exclusively deep-cycle batteries, but such batteries are not discussed in this article.
Car batteries differ in size, too, with the top 10 most popular car BCI group battery sizes:
BCI Group 24 Batteries
- BCI Group 34/78 Batteries
- BCI Group 35 Batteries
- BCI Group 47 (H5, L2, 55L2) Batteries
- BCI Group 48 (H6, L3, 66L3) Batteries
- BCI Group 49 (H8, L5, 88L5) Batteries
- BCI Group 51 and 51R Batteries
- BCI Group 65 Batteries
- BCI Group 75 Batteries
- BCI Group 94R Batteries
Of course, other BCI battery groups are used as well, but not as often as these ones.
The Weight Of The Car Batteries By Their BCI Group Size
The following list shows the average car battery weight according to the car's battery size/group and chemistry:

As one can see, BCI Group 24 batteries are mostly deep-cycle and dual-purpose batteries used in cars with dual battery systems.
BCI group 24 batteries on average weigh 43-57 pounds (~19.5-25.8 kg) and are still mostly lead-acid batteries.
However, if you need a starting BCI group 24 battery and you are unable to find one, consider getting a starting group 34 battery - they are smaller and lighter, but they are optimized for starting/cranking applications and can provide stronger currents than deep-cycle group 24 batteries.

Few Final Words
When the weight savings can bring an increase in performance, switching from lead-acid to lithium batteries can save some weight.
For passenger, SUV, RVs, and similar vehicles, the weight of the battery is not that important, although it may be important when the battery has to be carried by an individual, especially for longer distances.
However, vehicles that feature larger dual-purpose or even deep-cycle battery packs can significantly save in weight if they replace their lead-acid BCI Group 31 Batteries or BCI Group 4D/6D/8D Batteries with ultralight lithium batteries.
