Better for the environment, better lifetime and often more powerful, rechargeable batteries are typically more powerful than their disposable equivalents.
What Are The Best Aaa Rechargeable Batteries
Rechargeable batteries suffered from high battery drain, lost a lot of power when idle, and were unsuitable for many tasks. For example, in remote controls, rechargeable batteries would die at more regular intervals than standard disposable batteries, making them an inconvenient option. However, improvements in technology mean that there are now rechargeable devices that can rival alkaline models for longevity.

Additionally, rechargeable batteries can deliver more power than their alkaline equivalents, as proven in our performance tests where we measure the capacity of each battery. This makes rechargeable devices better for game controllers, toys, and even flashlights.
There are some products that require the use of alkaline batteries, such as smoke alarms. check the manual of the device you want to use to see if it can be used with rechargeable batteries. In most cases, you will be able to. Where you need to use regular batteries, see our guide to the best AA and AAA batteries.
We get four batteries from the same manufacturer so we can average our results. We test all rechargeable batteries using the Ansmann Energy XC 3000 battery test. Using this, we charge the batteries and confirm that they have a starting voltage of at least 1.2V.
We then put the batteries through 10 charge and discharge cycles using a high load of 600mA (+/-20%), stopping when the voltage reaches 0.94V. This gives us our starting capacity in mAh (milliampere-hours), being larger. the better.

We then repeat this test four more times (50 cycles), taking the results after ten cycles to ensure that battery performance does not deteriorate with use. This allows us to find the best batteries. We also consider the end use: high-capacity batteries may be ideal for flashlights, but cheaper, low-capacity batteries may be more suitable for remote controls or solar lights.
AA GP ReCyko Pro 2000mAh batteries can do it all. While most will last around 500 charge cycles, these will last a whopping 1500 cycles, three times longer. This helps offset the slightly higher asking price, as these batteries will last longer than the competition.
Not only that, the GP ReCyko Pro 2000mAh AA can hold 70% of its charge after five years. In other words, you can load them up today, stash them in a closet, and have them ready for action when you need them.
With an initial voltage of 1.4 V, these batteries were above the lower limit of 1.2 V for rechargeable batteries. The capacity is decent. With a nominal capacity of 2000mAh, we found that these batteries had an initial output of 2218mAh and this did not change over the 50 cycles we put the batteries through. It’s enough to handle the most powerful tasks, although if you really need more power, the Ansmann Digital AA HR6 2850mAh might be better.

For versatility and longevity, GP ReCyko Pro 2000mAh AA batteries are the best rechargeable batteries we’ve tested.
The name of the product, Ansmann Digital AA HR6 2850mAh, tells you everything you need to know. They are very high capacity rechargeable AA batteries with a high capacity of 2850 mAh. We can confidently say that this is correct and in our tests, the Ansmann Digital AA HR6 2850 mAh battery delivered a high capacity of 2911 mAh with little variation over every 50 cycles.
The power is high and makes these batteries suitable for the most demanding tasks, such as demanding games or very bright flashlights.
Durability is also excellent, with the batteries lasting 1000 charges, twice as long as standard rechargeable batteries. These will hold 60% of a year’s charge, which is a slightly steeper drop than much of the competition, so it’s best to charge the Ansmann Digital AA HR6 2850mAh and use it fresh.

The other thing is the price: they are more expensive batteries than much of the competition. If you need the extra power, it’s worth the extra expense. If not, a lower capacity battery pack may do the job.
Amazon Basics High Capacity AA 2400mAh rechargeable batteries are not “basic”. Great value, especially when bought in bulk, and great capacity, all products are great.
Running our standard battery tests, we found that the battery managed a charge of 2677 mAh, which is a bit higher than the nominal value. These batteries are a very good choice for demanding applications such as gaming and high power batteries. The starting voltage was 1.4V, which is above the minimum required of 1.2V.
There are some disadvantages. First, the load retention is only 70% after six months and 50% after one year; therefore, these batteries are used fresh and are not so good for low power devices such as remote controls. Second, Amazon says the battery will last for “hundreds of charges,” but doesn’t say how many.

If you’re buying in bulk, these batteries are a great value, so make a good choice if you need a lot of high-powered batteries. If you need more flexibility, the GP ReCyko Pro 2000mAh AA might be better.
Eneloop AA batteries are built to do almost everything alkaline batteries can do, so they are perfect replacements in some situations.
First, Eneloop AA batteries can be recharged 2000 times (or more), meaning they will last a long time. These batteries require more charge cycles than others we’ve reviewed.
Incredibly, they will also retain 70% of their charge for ten years, so you can use them on remote controls (for example, remote devices without fear of naturally discharging them). This is also good news if you want batteries that you can charge and have ready to go.
Best Rechargeable Batteries For Solar Lights
The downside is that the capacity is not that great. Eneloop rates these batteries at 1900 mAh, and our tests showed a capacity of 2101 mAh, with very little variation over our 50 test cycles. For higher consumption use like gaming controllers, you’ll probably want higher capacity batteries like the GP ReCyko Pro 2000mAh AA.
The batteries are also quite expensive, but if you need an instant replacement for a set of alkaline batteries, there’s nothing better.
The problem we all have with rechargeable batteries is that they aren’t ready when we need them. In many cases, we will turn to alkaline batteries when needed immediately. GP Recyko Charge 10 AAs are here to solve this problem, as they can be charged up to 90% at basic speed, provided you use them with the special charger.
This is great for convenience, but be aware that fast charging reduces battery life: fast charging only gives you 250 cycles, while slow charging stretches it to 700 cycles. We recommend charging only when necessary.

The capacity is only 1700 mAh, although they managed 2045 mAh when charging slowly, rate it above that capacity. With fast charging, the power was 1769 mAh.
If you need the flexibility to quickly charge your batteries, then there’s nothing like these competing models. If you can preload the sets, there are high-capacity alternatives.
The Amazon Basics Rechargeable AAA 800mAh shows that decent rechargeables don’t have to cost a fortune, especially if you have to buy them in bulk.
These batteries are rated to last 1000 charge cycles, which is a significant amount of time and longer than much of the competition. And, these batteries will retain 80% of their charge after two years, making them a great choice if you need batteries you can charge or store, or for low-power use like remote controls.

The capacity is 800 mAh, which is pretty standard for AAA batteries. We found this number to be correct and measured a capacity of 844 mAh with little change over 50 test cycles.
Overall, the combination of longevity, price, and power makes the Amazon Basics Rechargeable AAA 800mAh the best AAA rechargeable batteries you can buy.
While most high-powered devices require AA batteries, there are some, such as some flashlights, that run on AAA batteries. For such devices, Ansmann Micro AAA 1100mAh is the best choice.
These are the AAA batteries we tested, 1100 mAh. In our tests, over 50 cycles, we saw a capacity of 1050 mAh, which is slightly below the nominal value, but the highest of all AAA batteries.

Longevity is also good. Ansmann Micro AAA 1100mAh lasts for 1000 cycles and will hold 80% of the charge even for a year.
Amazon’s flagships are better value and suit most people’s needs, but if you need the extra power, these are the ones to get.
One of the most popular brands of batteries, Energizer Max AA, had a high consumption.
