Nowadays, along with the inspiring concept of environmental protection and better domestic waste disposal, rechargeable batteries have met with a more favorable reception since their popularity at the beginning owing to the recyclability and economies. What's more, rechargeable batteries get themselves in such a favorable position not merely because they are cheap and recyclable, more importantly, fast recharging gives people greater convenience compared to disposable batteries.
To make convenient, fast recharging happens, rechargeable battery chargers have evolved constantly from the initial generation. Since they evolve in a highly competitive manner, everything concerning the charging ability, compatibility, heat control ability, has been greatly improved. Many rechargeable battery charger testers have experienced all sorts of most up-to-date battery chargers for AA and AAA batteries. In the following paragraphs, I will sort out 10 best rechargeable battery chargers for AA and AAA batteries in 2019, which have been fully tested and reviewed by people in an unbiased way.
Many customers are happy with this product simply it works as expected, or more likely it comes with 4 AA batteries and 4 AAA batteries. Anyway, let's see how the charger serves its purposes.
This 8-bay battery charger is made widely compatible with AA, AAA Ni-MH Ni-CD rechargeable batteries, but not for alkaline or Lithium batteries. The multi-bay design enables it to charge up to 8 pieces of batteries at a time, however, you can only charge batteries in pairs, it won't work for batteries in an odd number. I guess we don't bother to figure this why out. It also has LED indicators showing the charging level.
Likewise, the recharging speed is fast and satisfying. But we would like to focus more on its unique function, the Trickle Charge. The Trickle Charge is something special that uses an intelligent cut-off charging method, called delta V, which is able to slow down the quick charging when batteries almost reach a full charge, namely, the charge becomes trickle charge, and finishes the charging bit by bit in a more safe way. Besides, the battery charger has advanced protection to stop unwanted overheating, higher voltage. It will automatically stop charging when the voltage goes up to 3.4 volts for the sake of safety.

AmazonBasics has been a very well-known brand in this field and the charger we recommend today is a multi-functional one that charges more than just rechargeable batteries.
The four charging slots accommodate 2 or 4 AA/AAA Ni-MH batteries at a time, still, batteries need to be charged in pairs. Built-in protection will automatically prevent over charge, as well as reversed battery polarities. Auto detection tells you a certain battery is incompatible, like an alkaline battery, or a bad cell battery, no longer workable.
The battery charger has a retractable AC plug that fits worldwide 100-240 volts AC standard. The slim charger can be also used as a portable power bank thanks to the USB port. The USB outputs 500mA for the maximum, which is enough to charge a cell phone, iPod or other USB devices. The USB port enjoys charging priority over AA, AAA batteries. When your USB device is fully charged, the charger will resume the rechargeable battery charging automatically.
EBL battery chargers are inevitably quite similar to each other, but sometimes they differ from each other too, functionally. Like this 12-bay battery charger, it can do more than an AA, AAA battery charger usually does. The multi-purpose charger works for AA, AAA, and 9V rechargeable batteries of Ni-MH and Ni-CD kinds. Thanks to the 12 battery bays, it can charge 1 to 10 pieces of AA, AAA batteries and 1 to 2 pieces of 9V batteries simultaneously. As to the indicators, it has a small LCD screen to show the charging level for AA, AAA batteries, and 2 LED lights for 9V batteries.
For the Trickle Charge function, EBL battery chargers basically share the same technology. Aside from the battery detection, it has intelligent control for safety protection, using advanced MCU control and delta V function to effectively safeguard the charger against short-circuit, non-rechargeable, defective batteries, over voltage, current or heating. Overall, the battery charger has a solid build and safe, efficient charging for AA, AAA, 9V batteries. A charger with so many charging slots is rarely seen on the market.
This Panasonic eneloop battery charger is generally reviewed as an excellent improvement in rechargeable household batteries. The charger structure is simple and easy to set batteries in. 4 charging slots are designed for 4 eneloop AA or AAA batteries to fit in and get recharged fast. It will take approximately 3 hours to charge them fully. When charging 2 pieces of AA or AAA batteries, it will be even faster, ideally an hour and a half you will have them recharge in full. To let the user easily read the charging levels, the battery charger has 4 individual LED light indicators. Green light means about 80% to 100% recharged, orange light means 20% to 80% and red 0% to 20%. When a certain battery is completely recharged, its indicator will turn itself off.
This highly efficient battery charger uses a retractable AC plug for direct power connection to an AC outlet, making easy and safe to handle the electrical cord and power connection. For more safety of battery charging, the charger adopts an advanced "battery sensing" technology built-in, which will enable to the charger to automatically stop charging when it senses a non-rechargeable battery in the charging slot.
