Having multiple battery types doesn’t mean buying multiple chargers; the SunLabz Smart Rechargeable Battery Charger for AA, AAA NiMH NiCD Batteries can charge both AA and AAA batteries simultaneously. Who needs a charger without batteries? Get the SunLabz AA High Capacity NiMH Rechargeable Batteries to go with your charger. They’re also available in AAA sizes.

SunLabz Smart Rechargeable Battery Charger for AA, AAA NiMH NiCD Batteries – Available in 3 Sizes

SunLabz technology is a manufacturer that’s focused on portable power; it is specialized in the manufacture of rechargeable batteries and their chargers. With an intense commitment to protecting the environment, it manufactures NiMH batteries that last extra-long, just so the world uses less batteries. It also makes solar chargers, power banks, and Bluetooth LED bulbs with conscious efforts to ensure they are “green”. This brand is so creative and innovative that it won’t compromise on design; so, its products are also sleek, with great colors and style.

If you use rechargeable batteries, you need to have a way to get their juices back up when they run down. If you have multiple battery types, which you likely do, we’re happy to tell you that you don’t need to get chargers for each type. This SunLabz Smart Rechargeable Battery Charger will help you recharge your AAA and AA batteries. If you have a bunch of them, you still don’t need to bother about how they’ll take turns to get charged, as this charger can power up 4 of each type simultaneously. This saves you plenty of time with enough batteries to use, soon.

This smart charger is specially designed for NiMH/NiCD rechargeable batteries. It’s called smart because it can detect faulty batteries that are plugged in, monitors the battery condition and charge status, and communicates them all back to you via its backlit LCD screen. One awesome thing about this charger is that it does all these on individual batteries—all 8 of them (or more if you go for one of the larger units)!

You can also call this charger high-tech because it uses the advanced Delta-V as its control function, which is how it does all its cool tricks that save you time and hassle. You won’t have to wait long on your batteries before they get charged, even after you’ve stored the batteries away for a while. Just make sure you’re using one of those top-quality batteries with long shelf life. You’ll also get up to a thousand charging cycles out of this smart charger, so you’re surely going to be using this for a long time. Are you thinking of a pet name yet?

Charging will stop when the battery is full to prevent overcharging. But, you should still take a quick peek at the indicator once in a while because, for some reason, your batteries may be discharging. It’s also safer to take out your batteries once the indicator shows they are full. Oh! Did we tell you this rechargeable battery charger has a 1-year warranty? You heard right, you have the manufacturer’s word.

Since you’ll need even more batteries to charge, check out the AmazonBasics variety of rechargeable batteries.

Amazon Basics is a subsidiary of the global online retail store, Amazon. It sells superior-quality products that span several areas to provide valuable solutions to people’s needs all over the world. It has a broad range of products to its name in several categories such as audio devices, camera accessories, storage devices, beddings, travel accessories, kitchen and dining, and so much more.

The first thing you’ll notice about the Amazon Basics High-Capacity Battery Charger is its size. It’s small and you will immediately start thinking how well it will fit in a bag. Amazon Basics knew this product’s potential for mobility, so it decided to make it function with extra portability. This charger will mount directly onto sockets and its AC plug pins are retractable, which further reduces its already-small footprint.

It has a built-in power switching technology that gives it a voltage range of 100 – 240. And yes, you guessed right; it will work anywhere in the world. Between you and us, let’s just rename this high-capacity charger ‘Amazon Basics Travel Charger’. That’s quite close to reality, isn’t it?

This charger will accommodate four batteries at a time, whether it’s AA or AAA. One thing, however, is that the charger will only work with a pair of batteries in it, either two AA or AAA batteries.

So, if you’re traveling with it, you might not even need to take your phone charger with you. This ‘travel charger’ has you covered. It might not have a screen to show you the status of things, but it has an LED light that glows green to indicate the USB port is available or charging. A red light means your regular batteries are charging, and flashing means you have an Alkaline battery installed (or a defective one). And when it goes off—you got it—charge complete!

We guess you might be wondering if you can charge your regular batteries and a device at the same time. The truth is, this charger is designed to give priority to the USB port, for obvious reasons. But once your device is fully charged, it automatically switches back to charging your AA/AAAs.

How Do I Choose the Best NiMh Charger?

Batteries have come a long way in helping us accomplish things. We have witnessed several iterations of them with improved capacity and efficiency. The best improvement we’ve seen in portable consumer-level batteries is their ability to recharge. This led to the creation of Nickel Metal Hydride (NiMH) batteries which are not only rechargeable, but are also environment-friendly and recyclable. Not surprisingly, these batteries became popular and so did their chargers.

The best NiMH chargers don’t just recharge your batteries—they are “smart”! They can detect a defect in your battery and can tell when the battery is full, and then cut off the flow of current. Some help you discharge and even refresh them, preserving and helping them function optimally. They can also charge multiple types of batteries, be it 9V, AAA, AA, etc., and the best part is that they can charge them simultaneously.

NiMH chargers are of different shapes and sizes. Different chargers can hold a different number of batteries at the same time. Most chargers can charge batteries individually, as well; that way, you can mix batteries with different charge levels without any issues. The rest of this article will guide you through choosing the best NiMH charger for your intended use.
How valuable a battery charger is to you depends on how many of your needs it meets. Most often, the type and number of features a NiMH charger has are what determines its price. A solid charger with a high capacity and nice features can cost over $50; a 4-slot charger with enough features to adequately serve its purpose can go for around $18. We want to call your attention as well to the cheap NiMH chargers that promise everything—the only attention you may give these is to ignore them because they tend not to last as long and what’s the use of having to replace the charger if you working to stop replacing batteries?
Disposable batteries are beginning to fade away because it is now apparent that filling our landfills with them is detrimental to our world. Rechargeable batteries are fast taking their place and they need to be recharged. If you’re going with the trend, you’ll surely need battery chargers. In that case, the following are features you might want to consider when making a selection:
  • Design
  • Capacity
  • Compatibility
  • Size
  • Charge Time
As you read on, you’ll learn how these features affect the performance and benefits of battery chargers.
Construction and Design
We’re sure you’re aware that NiMH rechargeable batteries come in different sizes but not all NiMH chargers are made for all battery sizes. Most of them are designed to accommodate the AA and AAA sizes, but you will find some that have slots for the 9V size. You might have also noticed that the C and D sizes are not so popular anymore. While most newer devices don’t use those sizes anymore, you may have some older ones that do – so you will have to make sure that the charger you choose can handle them. Many of these come with C and D-sized spacers that allow you to fit in two or more AA or AAA batteries into those same slots as well.

Most NiMH chargers will work well for Nickel Cadmium (NiCad) batteries too, while a few will also charge Lithium-ion. However, it’s important that you confirm if the NiMH charger you want to buy is compatible with Lithium-ion, as some of them won’t charge that battery type.

If you have lots of batteries and decide to go for a charger with only four slots, you’re sure going to wait a long time to get all your batteries charged; you’ll be better off going for a charger with a higher capacity. Some NiMH chargers have up to 16 slots to accommodate AA or AAA batteries – but the most common are 4 and 8 slots. These chargers come in different weights and sizes, as well; obviously, the higher the capacity of the charger, the bigger it will be.
Performance and Ease of Use
How fast rechargeable batteries fill up depends on the capacity of the battery and the amount of current flowing into the battery. A 2000mAh battery recharging at 200mA will take a significantly longer time to become full than one with a capacity of 800mAh. On the other hand, a charger that allows a flow of 700mA of current will charge the 2000mAh battery faster than one recharging at 200mA. It’s worthy of note that a charger with a high recharge current output is likely to shorten the lifespan of your battery if indulged too often.

How NiMH chargers are designed is what usually tells them apart. Some sport LCD screens that show you the status of the batteries being charged. Some of these screens will even inform you of the capacity charge so you can know how close it is to getting full. Further, some chargers let you discharge, refresh, and test the status of your battery; all you have to do is switch between these modes.

Most rechargeable battery chargers are fitted with charge detectors that shut off when your battery is full to minimize overcharging. Short-circuit, overheating, over-voltage, etc. are some of the protections certain NiMH chargers are designed to offer. You’ll also find that some chargers have individual slot charge, which lets you charge batteries with different charge statuses at a time—whether it’s just one battery you want to charge, or you want to utilize all the available slots at once.

The chargers with four slots are ideal for travel as they are portable. There’s even some that are fitted with a USB port for charging your smartphone and other devices – talk about getting great bang for your buck! That’s great innovation, as you’ll have two chargers in one. A lot of these 4-port chargers have plugs are retractable, making these chargers even more portable. The larger chargers with higher battery capacities usually have AC cords to connect them to power sources.

By the way, if you’ve been wondering what trickle charging is, here you go. It’s a form of charging that occurs after your battery is supposedly full. It further cramps some more power, by sending low current at a fixed rate, into your battery ensuring it is truly full. Some NiMH chargers are equipped with this feature and your battery will actually get a ‘trickle’ extra power to serve you.

There are chargers that will alert you if you have a defective battery installed, or that won’t even attempt to charge it at all. It’s not rare to find some chargers that are bundled with batteries, sometimes pre-charged, so you can start using them straight away. The number of batteries bundled with the charger will often vary from brand to brand. So, it’s up to you to look out for what suits you best.

Now you have it: sufficient information to help you decide on the features you consider most important in an NiMH battery charger. This will also help you choose the best NiMH charger for your needs.

Get the Best NiMh Charger of 2022!

We’re so glad you got to the end of our review. We hope you’ve been intimated with the relevant information you need to make a choice. Now accomplish your mission—go ahead and purchase that selection. We’re sure it will turn out to be the best NiMH charger for your needs.
