We can all agree that moving from alkaline to rechargeable batteries is a smart move, particularly if you use batteries at a swift pace. In general, rechargeable AA and AAA batteries last longer, cost less money, and produce less trash. The logical next step is to invest in a rechargeable battery charger so you can maintain your batteries from the convenience of your home. Additionally, purchasing the best rechargeable battery charger is equally as crucial as purchasing high-quality rechargeable batteries. Let's look at some of our best choices below.

Some rechargeable battery chargers have the ability to charge up to 16 or even 40 batteries at once.

You'll need many rechargeable batteries if you own a lot of devices. Below is the list of the best rechargeable battery chargers to keep your batteries charged. 


In-depth Reviews

We conducted our research on a few dozen rechargeable battery chargers on the market and found these five best chargers that are worth taking a look.

1. Panasonic Eneloop BQ-CC55 - Best AA and AAA battery charger

PRODUCT SPECS: 

  • Brand: eneloop

  • Product Dimensions: 1.13"D x 2.69"W x 4.75"H

  • Color: White

  • Input Voltage: 240 Volts

  • Item Weight: 0.26 Pounds

TODAY’S BEST DEAL: 

View Amazon

PROS:

  • Charges AAA (LR03) and AA (LR6) batteries

  • Ability to charge from one to four batteries at once 

  • Each battery has LED charging indicator

  • Smart charger

  • Can identify faulty batteries

  • Built-in socket in the back (cordless)

  • Lightweight

  • Inexpensive

CONS:

  • After 3-hour charging, the batteries become very hot. 

  • A mild sound of power running through each battery.

The Panasonic Eneloop BQ-CC55, which has four slots, is easy to use. First, insert the batteries - any brand of AAA or AA NiMH batteries will work. After that, simply open the AC plug, attach the charger to your power outlet, and await the status light indicator to show that each battery has been fully charged. 

When the batteries complete charging, an auto-shutoff function detects their level of charge and immediately turns the power off. The BQ-CC55 scored admirably in our drain-time and battery-capacity testing and it comes from a manufacturer we have faith in based on years of user experience. It also has a plain, unassuming appearance that will blend into most rooms' backgrounds.

2. EBL 6201 - Best Charger via USB

PRODUCT SPECS: 

  • Brand: EBL

  • Color: Black

  • Charging Time: 3.5 Hours

  • Input Voltage: 5 Volts

  • Output Voltage: 3 Volts.

TODAY’S BEST DEAL: 

View Amazon

PROS:

  • 2 Hours Fast Battery Charger

  • Separate AA AAA Battery Charger

  • Auto-detect Function

  • Advanced MCU Control System

  • Type C or USB Charging ways

CONS:

  • Only compatible with the USB cable that comes with it.

  • After two hours of charging, All Ni-Mh batteries get EXTREMELY HOT

  • Some users complain that some of the compartments stop working after a few times of usage. 

Many of the functions available on the Panasonic BQ-CC55 are also included on the four-bay EBL 6201 charger: It can simultaneously charge up to four NiMH batteries, automatically shuts off power after charging is finished, has notification lights above each battery slot, and is reasonably small and portable. 

However, the EBL incorporates USB input ports on the side in place of an AC socket, allowing you to charge your AAA or AA batteries with any Micro-USB or USB-C cable and power source of your choice (a laptop, power bank, or wall charger).

Therefore, rather than using up an entire outlet, you may plug the EBL into a USB wall charger that is already present in the area where you want to charge your batteries, such as near a desk or bedside table.

3. Tenergy TN480U - Battery Charger with The Most Slots

PRODUCT SPECS: 

  • Brand: Tenergy

  • Item Weight: 145 Grams

  • Product Dimensions: 3.94"D x 5.39"W x 1.02"H

  • Input Voltage: 240 Volts

TODAY’S BEST DEAL: 

View Amazon

PROS:

  • Intelligent charging - Completely recharge one to eight AAA/AA NiMH batteries without pairs.  

  • Rapid Charge - Each slot can recharge at up to 500mA speed of charging. 

  • Convenient USB inputs - Recharge anywhere with the micro USB or USB C input. 

  • Protections - includes integrated safety protections

  • Easy to read - receive in-depth charging information for each slot. 

CONS:

  • Might not be compatible with every type of rechargeable battery.

For those who frequently need to charge a large number of NiMH batteries at once, the Tenergy TN480U eight-bay charger is the best option. It charges from two to four A batteries and has eight slots for separately charging them. On a scale of one to five, the TN480U's screen indicates which batteries are being charged and their level of charge.

Since this charger is more compact and smaller than the majority of the eight-slot chargers we've examined, it blends in well with its surroundings. When looked closely, the screen is bright and easy to read, but when seen from a distance, it is nicely subdued.

The TN480U is powered by USB-C or Micro-USB or and is provided with a rubber-band cable tie and a Micro-USB charging cable. However, you'll need to get your own USB wall charger.

  • Brand: Tenergy

  • Color: Black

It also enables you to monitor the capacity, voltage, internal resistance, and charge cycles of your batteries. The size-adjustable slots on this charger allow you to charge a wide range of battery types, including two to four A batteries and C batteries, in contrast to the rest of our recommendations.

Questions from Users

1. Who uses rechargeable battery chargers?

Anyone who wishes to make a difference can use these rechargeable battery chargers. Rechargeable batteries can save you a ton of money while also protecting the environment. By avoiding the purchase of new batteries every time the old ones burn out, you can decrease the quantity of disposable waste released. If you're looking for a one-time-investment battery charger, then this is definitely for you.

2. Do all batteries function the same way?

Rechargeable batteries typically last between two and five years and can be charged repeatedly. Despite costing more than alkaline batteries, they are ultimately more cost-effective because of their extended lifespan. On the other hand, non-rechargeable batteries work well but deteriorate quickly. One of the difficulties cited by customers is the fact that rechargeable batteries can have a lower voltage rating than single-use batteries. This might have an impact on the output and functionality of a device. This isn't always the case, though.

3. Is it worth buying a rechargeable battery charger?

Rechargeable batteries can run out and then be reused. Non-rechargeable batteries, however, cannot be recharged after they have been completely used up. This is the primary distinction between non-rechargeable and rechargeable batteries.  

Batteries that can be recharged cost more than non-rechargeable batteries. In the long run, however, using rechargeable batteries is more cost-effective. Non-rechargeable batteries may appear more inexpensive than rechargeable ones, but when you have to replace them every few months, the cost adds up.


Our Pick

Energizer AA and AAA Battery Charger with 4 AA NiMH Rechargeable Batteries, Recharge Pro Battery Charger for Double A Batteries and Triple A Batteries

To sum up, the Panasonic Eneloop BQ-CC55 would be the best rechargeable battery charger we’d pick. It incorporates notification LEDs over each battery slot and a fold-out plug that allows it to fit flat on your wall outlet. Additionally, four batteries can be charged simultaneously.
