![]() Nickel-Zinc (NiZn) batteries have been around for over a century, but it is only in recent years that they have started to gain traction as a viable alternative to other rechargeable battery chemistries, such as Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH). Source: The sample for this review was provided by EBL.Exploring the Advantages and Applications of Nickel-Zinc (NiZn) Batteries If you need a mess of NiZN AA’s, then I recommend looking at this gadget from EBL. The charger’s very simple design worked exactly as expected. I found that EBL’s batteries did a great job powering my lantern and my Speedlite, and despite their slightly larger diameter, I didn’t have any problems removing them from these gadgets. NiZN batteries aren’t for everyone, but if you have a high-drain device, they can provide the power you need. Prominent warnings to avoid using these batteries in other chargers and other batteries in this charger.Extra power for those gadgets that can use it.The ability to charge all eight at once.I would be happy to bring a couple sets of four to a photoshoot. I can’t tell that the pictures were brighter when compared to alkaline batteries from Duracell, but they worked without any problems. ![]() The NiZN batteries had no problem powering the flash, even when firing repeatedly. When repeatedly shooting flash photography, the batteries in my flash can drain in a hurry. The second device was a Speedlite 430EX II, an external flash for my Canon DSLR camera that uses a set of four AA batteries. In the photo above, the lantern on the right has the NiZN batteries. At each of the four settings, the lantern with the NiZN batteries was noticeably brighter than the one with alkaline batteries from Duracell. When I replaced the alkaline batteries in one lantern with EBL’s NiZN batteries, I could see the difference. Each lantern takes six AA batteries, and on the highest setting can put out 500 lumens, more than bright enough to light up the back porch. We often grill after the sun has set, so these lanterns are perfect when we need to check how well done our meat is or to see while eating. They’re designed for camping, but we tend to use them in the backyard while grilling on our Breeo. ![]() The first device was a pair of Craftsman LED lanterns. Time will tell whether this is true of these batteries. Three, historically NiZN batteries have not held their charge very well once they’ve been cycled more than 50 times. Two, these batteries are ideal for high-drain devices, anything that uses a lot of power in a short period of time, like a portable video game player, a radio-controlled toy, or an external camera flash. I need to be careful not to use them in any gadget whose circuitry could be sensitive to this higher voltage. When freshly charged, their terminal voltage can be slightly higher, around 1.85v, which can be hazardous to some gadgets. One, it has a nominal voltage of 1.6v, which is higher than normal AAs. Performanceīecause these are NiZN batteries, there are a few differences from the alkaline or NiMH batteries that I typically buy. While charging, small LEDs above each battery turned red when finished, they turned green. I plugged the USB-A side into my Soundcore Wakey and the micro USB into the top of the charger. ![]() EBL has been delivering batteries and chargers for 24 years, and their mission is “to deliver the highest quality and most reliable batteries possible.” They are headquartered in China. They have a 3000 mAh capacity, use 1.6v, and can be recharged 1000 times. This is a set of 8 rechargeable Nickel-Zinc (NiZN) AA batteries with a charger. Today I’m going to be reviewing NiZN AA batteries from EBL. What you may not know is that there are a host of other types of AA batteries that use different materials internally, each having slightly different properties and uses. They are all the same size (diameter 14.5 mm, length 50.5 mm) and have a standard range for voltage (1.2 to 1.5v), though their capacity can vary widely (typically from 1000 to 2800 mAh). REVIEW – You’re familiar with standard alkaline AA batteries from companies like Duracell, and you are probably familiar with rechargeable NiMH AA batteries, like these from Energizer.
