How Much Does AA Battery Weigh? (Weight Breakdown & Types)

Have you ever wondered how much an AA battery weighs? I’ve always been curious about their weight as someone who relies on these little powerhouses to keep my devices running.

First of all, did you know that the weight of an AA battery can vary depending on its type?

Alkaline AA batteries, the most common type, weigh around 23 grams or 0.81 ounces. Lithium AA batteries, conversely, are a bit lighter, coming in at around 15 grams or 0.53 ounces. And if you’re using rechargeable Ni-MH batteries, you can expect them to weigh around 31 grams or 1.1 ounces.

But that’s not all – there’s even more, to discover about the weight of these little powerhouses!

Regarding AA batteries, the weight can vary depending on the battery you use.

The weight of an AA battery can range from 19 to 29 grams. However, the exact weight will depend on the AA battery you use.

For example, a carbon-zinc AA battery is significantly lighter than a nickel-cadmium one.

If you’re curious about the weight of rechargeable AA batteries, they tend to be a bit heavier than non-rechargeable ones.

Rechargeable AA batteries weigh about 31 grams, while non-rechargeable ones weigh between 19 and 29 grams.

It’s worth noting that the weight of an AA battery may not seem like a big deal, but it can make a difference in certain situations.

For example, if you’re using a device that requires a lot of AA batteries, such as a camera or a flashlight, the weight of the batteries can add up quickly.

You may consider using lighter batteries to reduce the device’s overall weight in these cases.

Factors that Affect the Weight of an AA Battery

As someone who has used a lot of AA batteries over the years, I’ve always been curious about what factors contribute to their weight. Here are a few things I’ve learned about what affects the weight of an AA battery:

Material Composition

The materials used in the construction of an AA battery can have a significant impact on its weight.

For example, alkaline AA batteries typically weigh around 23 grams, while lithium AA batteries are lighter, weighing around 15 grams.

Rechargeable Ni-MH batteries are the heaviest of the three, weighing around 31 grams.


The size of an AA battery is also a factor in its weight. AA batteries typically measure 49.2-50.5 mm in length, including the button terminal, and 13.5-14.5 mm in diameter.

The larger the battery, the heavier it tends to be.


Different brands of AA batteries can vary in weight, even if they have the same material composition and size.

This is because manufacturers may use different amounts of materials to construct their batteries or use different manufacturing processes that result in slightly different weights.

Why Does the Weight of an AA Battery Matter?

As someone who has used AA batteries for years, I can tell you that the weight of these little powerhouses matters more than you might think. Here are a few reasons why:

1. Portability

One of the biggest advantages of AA batteries is that they are portable. You can take them wherever you go, whether camping in the wilderness or working on a construction site.

However, if you’re carrying around a lot of heavy batteries, it can quickly become a burden. That’s why it’s important to choose batteries that are lightweight and easy to carry.

2. Power Output

The weight of an AA battery can also affect its power output. Generally speaking, heavier batteries have a higher capacity and last longer than lighter batteries.

However, this isn’t always the case; many factors can affect a battery’s performance.

That’s why choosing batteries specifically designed for your device and its power requirements is important.

3. Environmental Impact

Finally, the weight of an AA battery can also have an impact on the environment. Heavier batteries require more resources to produce and transport, which can lead to a higher carbon footprint.

Additionally, heavier batteries may be more difficult to recycle, leading to more landfill waste. You can reduce your environmental impact by choosing lightweight batteries and help protect the planet.

Wrapping Up

The weight of an AA battery ranges from 19 to 32 grams. Carbon-zinc batteries are the lightest, weighing only 19 grams, while rechargeable batteries are the heaviest, weighing around 32 grams.

It’s important to note that the weight of an AA battery is not the only factor to consider when choosing a battery.

Other factors such as shelf life, voltage, and price should also be considered. However, lithium AA batteries are the lightest option available if weight is a concern.
