How much does a 65 series car battery weigh?
A typical Group 65 car battery weighs about 50–60 pounds (23–27 kg). The exact weight depends on the battery’s chemistry and capacity, with AGM versions tending to be heavier than standard flooded models.
What is a 65 series battery?
The 65 series, also known as Group 65, is a large automotive battery size defined by industry standards. It’s common in full-size and some mid-size vehicles, including SUVs and trucks. The Group 65 format accommodates higher capacity and cranking power compared with smaller group sizes. This article explains how weight varies by construction and why the numbers differ across options.
Size and compatibility
Group 65 batteries share similar dimensions and terminal configurations that determine fitment in a vehicle's battery tray and cable routing. Always verify your vehicle’s owner manual or the existing battery label to ensure correct compatibility.
Common uses
Vehicles that typically use Group 65 include certain Chevrolet and GM SUVs, large sedans, and some European imports. Availability of AGM or high-output options varies by market and retailer.
Weight ranges by technology
Below are typical weight ranges you’ll see for Group 65 batteries, depending on whether the battery is flooded lead-acid or AGM, along with notes on high-output variants.
- Flooded lead-acid (standard): approximately 50–60 pounds (23–27 kg)
- AGM (absorbed glass mat): approximately 60–70 pounds (27–32 kg)
- High-output or heavy-duty variants: up to about 70 pounds (32 kg) or slightly more
These figures are approximate; exact weight will be printed on the battery label and can vary by manufacturer and model year.
Finding the exact weight
To determine the precise weight of a specific Group 65 battery, check the product specification page from the manufacturer, look at the label on the battery itself, or weigh it on a scale if you’re curious about installation considerations. When replacing an old unit, compare the new battery’s weight to the original to ensure proper handling and fit.
Summary
For most drivers, a Group 65 battery weighs roughly 50–70 pounds, with standard flooded options around 50–60 pounds and AGM variants toward 60–70 pounds. Always verify the exact weight from the manufacturer label when selecting a replacement to ensure proper fit and handling requirements.
