The built-in temperature control valve prevents the batteries from overheating. The large-area fan-shaped vents make sure that these batteries don't reach dangerous (above 158 degrees Fahrenheit) temperatures in the first place.
The batteries are somewhat inconvenient to store.
POWEROWL AA Rechargeable Batteries are the best AA batteries on the list. The pack will last you for decades. These things provide outstanding performance even when the temperature drops below -4 degrees Fahrenheit.

Equipping these batteries with micro-USB ports, the manufacturers have enabled you to recharge them via any device with a USB interface. The batteries take less than two hours (usually ~90 minutes) to fully recharge. They're not susceptible to the lead-acid memory effect.
The micro-USB ports are not moisture-resistant.
GTF USB Charge 1500mAh AA Rechargeable Batteries are much more practical than standard AA batteries because you don't have to purchase a battery charger (assuming you don't have one). If you do have one, these are still pretty handy all things considered.

The durable lattice alloy here increases hydrogen stability, reducing self-discharge and making sure that these batteries are able to maintain ~85% of the charge even after one year (when not in use). The batteries don't suffer from memory effect and will have no issues performing even when it is -4°F outside.
The battery wrap looks pretty bland.
Panasonic BK-3HCCA4BA Eneloop Pro Ni-MH Pre-Charged Rechargeable Batteries are pretty good batteries, though not without some flaws. They're as reliable as these batteries come and you can put these things into pretty much any device that runs on AA batteries.

The 2500-mAh capacity is awesome. You won't be able to find longer-lasting batteries within this price range. These are Ni-MH batteries, meaning that there're no Hg/Cd/Pb elements inside these things. The Duralock™ technology will make sure these batteries are able to reach 65-70% charge even after 10 years.
The batteries don't work especially well with non-Duracell chargers.
People with Duracell chargers should definitely opt for these batteries. Those who don't have Duracell chargers and don't really want to buy one will probably be better off with other batteries on this list. They're pretty good replacement batteries though.

Lasting Impression
POWEROWL AA Rechargeable Batteries are pretty awesome as far as AA batteries go.
First, the 2800-mAh capacity is hard to come by. That's double what ordinary AA batteries give you. Capacity like that means that the batteries will usually last for months (depending on where you put these things and how often you use the device).
At the same time, these are Ni-MH batteries, meaning that environmental concerns have been taken into account too. You won't have to worry about adding heavy metal pollutions to the environment.
These batteries last. The built-in temperature control valve prevents the batteries from overheating. Meanwhile, the large-area fan-shaped vents make sure that these batteries don't reach dangerous (above 158 degrees Fahrenheit) temperatures in the first place.
Provided you store them properly, these long-lasting batteries will be able to charge up to 70% compared to the original charge even after 10 years. Storing them properly can be somewhat inconvenient though because the supplied carton box most certainly doesn't count as a storage case, so you'll have to think of something.
In short, POWEROWL AA Rechargeable Batteries are the best AA batteries on the list. The pack will last you for decades. These powerful things provide outstanding performance even when the temperature drops below -4 degrees Fahrenheit.

Micro-USB Ports
The people behind GTF USB Charge 1500mAh AA Rechargeable Batteries understand that very few people these days have battery chargers and have taken these practicality concerns into consideration when they were designing the product.
Equipping these batteries with micro-USB ports, the manufacturers have enabled you to recharge them via any device with a USB interface. The only issue with these ports is that they don't come fitted with shutters, making them susceptible to moisture. With that in mind, we would recommend storing the batteries somewhere dry.
Besides these ports, we're dealing with pretty much standard AA batteries. They take less than two hours (usually ~90 minutes) to fully recharge. The 1500-mAh capacity means that these batteries don't make the charge last that long but that's always the case with lithium batteries compared to Ni-MH models.
On the bright side, lithium batteries are not as susceptible to the lead-acid memory effect, meaning that you can recharge these things as many times as you want without substantial battery life decrease.
In conclusion, GTF USB Charge 1500mAh AA Rechargeable Batteries are much more practical than standard AA batteries because you don't have to purchase a battery charger (we're assuming you don't have one). If you do have one, these are still pretty handy all things considered.

ProCyco Tech
EBL AA-16 2300mAh Rechargeable AA Batteries are solid batteries that don't really have any major downsides to them.
As far as we're concerned, the product's only flaw is that you'll have to recharge the batteries 3-5 times before you'll be able to reach the advertised capacity.
On the flip side, the advertised 2300-mAh capacity is nothing to scoff at. These batteries will last. You can put them inside things like flashlights and radios (items that you do not necessarily use that often) and make sure the batteries will keep these items performing for years to come.
The company's ProCyco tech pretty much guarantees the advertised ~1200 recharge cycles, which is fairly impressive considering that there aren't too many batteries that can match that number. The batteries can be recharged when they're fully as well as partially drained without any long-term issues.
The package includes four packs with four batteries inside each pack. You can use these packs as storage containers without worrying about the batteries' lifespan.
Bottom line, EBL AA-16 2300mAh Rechargeable AA Batteries don't leave much to be desired. These are easily the most well-rounded batteries we've looked at and the most complete product within this lineup. Plus, the batteries do not contain any Hg/Cd/Pb elements, meaning there's no pollution to the environment. You can recycle them too.

Increased Hydrogen Stability
Panasonic BK-3HCCA4BA Eneloop Pro Ni-MH Pre-Charged Rechargeable Batteries are somewhat difficult to categories.
On one hand, the 2550-mAh capacity is awesome, especially considering that these batteries are pretty cheap. The capacity means that these batteries will make that one charge last.
On the other hand, the batteries won't be able to give you more than 500 recharges, which is alright but we've seen better numbers on that front.
At the same time, the durable lattice alloy here increases hydrogen stability, reducing self-discharge and making sure that these batteries are able to maintain ~85% of the charge even after one year (when not in use).
The batteries long life aside, some like the relatively bland black wrap, others find it pretty boring, so we won't be focusing too much on appearance here.
We will, however, highlight that these batteries are pretty tough and will have no issues performing under extreme temperature conditions (as low as -4 degrees Fahrenheit).
Apart from that, the batteries don't suffer from memory effect, meaning that you can recharge them when they're fully or partially discharged.
Long story short, Panasonic BK-3HCCA4BA Eneloop Pro Ni-MH Pre-Charged Rechargeable Batteries are pretty good batteries, though not without some flaws. They're as reliable as these batteries come and you can put these things into pretty much any device that runs on AA batteries.
Duracell Approach
These AA-Rechx4 2500mAh AA Rechargeable Batteries are Duracell batteries. You know what you're getting from the company's products. They're not that great on paper. But you know that you can rely on these batteries on matter what.
About that "not that great on paper" part, that's partially true. You'll be able to recharge these things only up to 400 times, which is not exceptional compared to AA batteries within the same price bracket.
Having said that, you know that they'll give you those 400 recharges, something that you can seldom say about the company's lesser-known competition.
The 2500-mAh capacity is awesome. You won't be able to find longer-lasting batteries within this price range.
The batteries don't work especially well with non-Duracell chargers though, that's always an issue with Duracell batteries.
On the bright side, these are Ni-MH batteries, meaning that there're no Hg/Cd/Pb elements inside these things, ergo no pollution to the environment.
All things considered, people who have Duracell chargers should definitely opt for these batteries. Those who don't have Duracell chargers and don't really want to buy one will probably be better off with other batteries on this list. They're pretty good replacement batteries though.
What are AA Batteries?
We don't rely on AA batteries as much as we used to. Nowadays, it is all about gadgets and devices that come equipped with built-in rechargeable batteries. Having said that, there're still many different devices these days that run on these batteries.
From video game controllers to flashlights, from different toys to digital cameras, from clocks to shavers, from electric toothbrushes to baby monitors and many different wireless electronics, you need AA batteries to power these devices. Fortunately, there's not much to cover concerning these batteries.
First, you need to determine the type. Lithium and Ni-MH batteries come with their own advantages and disadvantages. After that, look into the advertised recharge cycles. These will tell you how many times you'll be able to recharge the batteries. They're not necessarily always accurate but you can ballpark the actual number based on the advertised one. Otherwise, it is all about the batteries' capacity since that will determine how long one charge will last.
Sometimes, these batteries come supplied with nice storage containers, which is great since you'll need to store them somewhere anyway.
