The best rechargeable AAs are integral to keeping your devices powered up and running at a fraction of the cost of traditional alkaline batteries over a long period of time. After purchasing and exhaustively testing over 30 rechargeable AA batteries, we narrowed our top choices to 7. To become a top pick, our scoring criteria places a premium on 500+ charge cycles, 2,000mAh+ capacity, the number of times it can be recharged, and how long they will hold a charge after periods of non-use. Rechargeable AA batteries are also great to use with the best portable phone charger.
After more than 100 hours of testing, Energizer’s Rechargeable AA Batteries are our #1 pick, clearing a second-best rechargeable AA battery capacity of 2,300 mAh and 500 recharging cycles, making it a top choice for high-drain devices such as digital cameras. It eeks out our honorable mention, Panasonic Eneloop AA Pre-Charged Rechargeable Batteries, with 300 more mAh and a more eco-friendlier composition for good measure. Once charged up, consider taking them on the go with you alongside any of the best portable chargers.
Kudos to Energizer for beating traditional Energizer MAX alkaline batteries’ power capacity up to 4 times while being safer for the environment. One downside observed during testing were its wildly varying pre-charges before the first time using them. 2 tests saw charges of 65% and 80% respectively, which may indicate different time to shipment between batches, resulting in battery degradation.. Like our honorable mention, the Panasonic Eneloop, these batteries also come pre-charged for instant use right out of the gate. Whether you use them in the best microscope or in a remote.
Another reliable choice from Energizer are the Recharge Universal AA and AAA batteries. Each battery can be charged up to a 1,000 times.
After 3 years of storage, Panasonic Eneloop AA Pre-Charged Rechargeable Batteries also keep up to 70% charging capacity after up to 10 years of non-use. This blows away our 5th place pick Duracell’s hold charge of up to 1 year without use.

We also appreciate the Eneloop’s durability, keeping its charge in temperatures as low as -4 degrees Fahrenheit. This makes it a solid choice for those crackling Alaskan winter trail excursions, needing a reliable charge for your lanterns and walkie talkies. Even things like the best dgital picture frame sometimes takes AAs.
AmazonBasics AAA High-Capacity Rechargeable Batteries also come pre-charged, making it ready for use immediately after unpackaging. Its pre-charge juice can be fully recharged even after not using it for 3 years, making it the perfect stowaway for your high school sophomore’s first day of college on campus pictures. You may not need these batteries for the best smart glasses, but there’s always something else.
POWEROWL AA Rechargeable Batteries also retain their power over a long period, with 70% capacity after non-use for 3 years. They are also very durable, maintaining performance in temperatures as low as -4 degrees. Value is also on point. Our tests reveal one POWEROWL rechargeable battery equal to 2100 alkaline batteries. It will work great with the best point shoot camera when traveling.
Duracell Rechargeable AA batteries are practical with mid-range battery usage devices and electronics such as baby monitors and video game controllers. Although its capacity and number of recharges lower than our top 4 picks, these batteries remain very serviceable for lower drain devices such as clocks, especially if are lucky enough to snare a “golden ticket” 1000mAh battery. For more of your battery needs, take a look at the best C batteries too.
Rayovac Rechargeable AA Batteries also has serviceable 5-year coverage. Compare that to Duracell, Panasonic, and Energizer power warranty at 10 years, 10 years, and 5 years respectively, and you have yourself a decently covered battery. For your additional battery needs, take a look at the best D batteries.
Although LP does not come close to Although LP does not match POWEROWL AA Rechargeable Batteries’ 70% of charge after 10 years or Energizer’s 10-year warranty, it offers enough power and reliability to keep your low drain devices charged for years
When choosing a rechargeable battery, we take recharge time, storage life, battery capacity, applicability to low/high drain devices, and operating temperatures into consideration.
Our ideal recharge times is 2-3 hours for 2000+mAh rechargeable AA batteries, which we felt was an acceptable wait time for high drain devices such as digital cameras with rapid-fire usage in short periods. Batteries with low battery capacity (<800mAh) also did not make our list to avoid having to recharge them every 2 hours. Common ranges go from 800 mAh to almost 3,000 mAh, with most topping out in the 2,300mAh range. Recommended cycle times also rate between 500 and 2,000 cycles, which offers cost per charge as little as several cents for outstanding value, especially when charging no more than twice a month.
Length of warranty was also a secondary factor, with a recommended time frame of 5-plus years.
