How to Pick the Best Rechargeable AA Batteries: Step-By-Step

There are several factors you must consider before picking the best AA rechargeable batteries for your devices. We’ll go over them now.

Battery Capacity

We measure rechargeable AA battery capacity in milliamp hours, or mAh. The higher the number, the longer a battery will last, making it ideal for high-drain use. Unfortunately, it may also mean that your batteries take longer to recharge.

Self-Discharge Rate

When not in use, rechargeable AA batteries naturally discharge or lose power over time. The self-discharge rate is an important factor to consider, especially when you intend to pre-charge your batteries and leave them ready to use. 

Most of the options in this guide promise to retain at least 70% of their charge for over a year. This is great, especially for low-drain devices that use little power over a long time. Batteries with high capacities typically retain significantly lower amounts of charge, which is fine because they are intended for use in powerful, high-drain devices.


Rechargeable AA batteries have a limited lifespan because they degrade over time. We measure their lifespan in charge cycles, which vary based on the chemistry and quality of the battery. The batteries on our list have between 500 and 1000 charge cycles, which means they’ll last several years before it’s time for you to recycle them.

What to Know Before Buying Rechargeable AA Batteries

Rechargeable AA batteries are becoming increasingly popular due to their cost-effectiveness and eco-friendliness. They’re also very convenient because you don’t have to run to the store every time your batteries die. Just charge them or reach out for a spare set of charged batteries. So, inevitably, sooner or later, you’ll find yourself reaching out for a pair or a value pack of rechargeable AA batteries to power your favorite everyday devices. When you do, it’s important that you keep in mind their shortcomings to ensure they perform optimally and last a long time.

For starters, rechargeable batteries are more expensive yet have lower capacities than disposable batteries. You end up spending more, especially if you don’t already have a charger. However, this high initial cost is spread over a longer period, which makes rechargeable batteries a cost-effective option in the long run. Charging times vary across different battery brands, and purchasing an option that takes a long time to recharge may be inconvenient if you want to use your batteries immediately. This disadvantage is also present when you purchase batteries that are not pre-charged before packaging. 

Using Rechargeable AA Batteries: What It’s Like

The first thing about rechargeable batteries is that they’ll power your devices for as long as they are charged. So, you’ll need a charger that’s compatible with their rated capacity and chemistry to keep them running. Charging times vary between different battery brands and may be determined by the charger you’re using and the capacity of the battery. Another thing is that rechargeable batteries perform best within certain temperature ranges. Some perform well in extreme temperatures, while others suffer from reduced capacity and lifespan when exposed to temperatures beyond a certain range.

Two options that perform well in extreme temperatures include the Tenergy Centura AA and the Powerex PRO AA NiMH. Unfortunately, the environmentally friendly Energizer Recharge Universal batteries incur a hit on their lifespan and capacity when exposed to extremely high or low temperatures. You should also know that rechargeable AA batteries have a limited lifespan, measured in charge cycles. The number of cycles varies depending on the chemistry and quality of the battery. Therefore, it is important to choose high-quality batteries and follow proper charging and storage guidelines to maximize their lifespan.

Our favorite thing about rechargeable AA batteries is that they reduce your carbon footprint because they require fewer resources and energy to manufacture. Additionally, they reduce the amount of disposable battery waste going to landfills, which is better for the environment.

Frequently Asked Questions

Can I recycle rechargeable AA batteries?

Rechargeable AA batteries can be recycled at many electronics retailers and recycling centers. You can find recycling centers near you by contacting your local household waste programs or through the Earth 911 and Call2Recycle databases. Recycling your rechargeable batteries helps you prevent further harm to the environment.

Can I recharge different types of rechargeable AA batteries together?

Manufacturers actually discourage people from charging different types of batteries together. That’s because they may have different charging requirements because of chemistry and voltage, which could easily cause damage.

How many times can I recharge my rechargeable AA batteries?

The number of times you can charge rechargeable AA batteries depends on the chemistry, battery capacity, brand, and quality of the batteries. Generally, NiMH batteries can be recharged 500 to 1000 times.

How long does it take to charge rechargeable AA batteries?

The time it takes to recharge rechargeable AA batteries depends on the capacity of the battery and the type of charger being used. Typically, it can take anywhere from a few hours to overnight to fully recharge a battery.

Can rechargeable AA batteries explode like disposable batteries?

Rechargeable AA batteries are typically considered to be safer than disposable batteries and are less likely to explode. However, it is still important to handle them with care and avoid puncturing or short-circuiting them.
