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 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.

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.

Top 7 Best Rechargeable AA Batteries Compared

 #1  Energizer Reacharge Plus NiMH Rechargeable AA Batteries – Top Pick/Best for High Drain Devices

WHY WE LIKE IT: The Energizer Rechargeable AA Batteries boast a battery capacity of 2300 mAh, 5-year battery life with regular use, 500-plus charging cycles, and 12 months of charge retention when not in use.

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 research was its wildly varying pre-charges before the first time using them. 2 researched evaluations 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.

How We Decided

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.

Rechargeable AA Battery Buying Guide

The Most Important Features to Consider

  1. Storage Life -When not in use, rechargeable batteries can self-leak and lose discharge. Look for batteries that offer low self-discharge and can at least maintain 75% of capacity after 3 years of non-use.
  2. Recharge Count – At a minimum, batteries should hold a charge on a minimum of 500 charge cycles, with 2000+ on the higher end. This yields a lower recharge to cost ratio and results in years and years of use without having to replace them. The highest volume alkaline packs by name brands typically carry 100 batteries for a 14 cent per unit cost, so you can do the math on value.
  3. Battery Capacity – Battery capacity is an indicator of how long devices will hold power until the next recharge. Using power-intensive devices such as walkie talkies, radios, or gaming systems need at least a month’s worth of action before needing a recharge or you may quickly lose patience. The highest battery capacity clicks in at 2,000mAh+, which prolongs the use of slow drain and high drain devices.

Rechargeable AA Batteries FAQs

How long do rechargeable AA’s last?

Rechargeable AAs that are charged and used consistently can last beyond 2000 recharges and maintain up to 90% of power after more than a year of non-use.

As a rule of thumb, you should use rechargeable batteries on moderate to high power consumption devices that need battery replacement every 30 to 60 days, such as walkie talkies and small portable radios. Low drain devices could do without it, as the price of rechargeable batteries and a charger may well exceed the cost of electricity over a year or more.

This is especially true with alkaline batteries.However, POWEROWL AA Rechargeable Batteries and Panasonic Eneloop batteries perform well in temperatures as low as -4 Fahrenheit due to their unique compositions.
