Panasonic eneloop BK-3MCCE/8BE Nickel Metal Hydride AA Batteries, Classic AA 8-Pack

Product Information

This number, which stands for milliampere-hour, covers the NiMH battery’s capacity and its ability to run a given load over a longer period of time. The higher the number on the battery, the bigger the capacity and the longer it will maintain an ample working charge while powering a specific gadget. We recommend you choose batteries with a capacity of 2,000mAh or more, so you don’t run out of charge when you’re half way through doing something, and you don’t need to recharge quite so often. The capacity is usually listed on the box as well as on the battery itself, and you will also see it listed if you’re buying batteries from an online store. What’s the best charger to buy? Most standard battery analyzers aren’t compatible with the 1.5V lithium-ion batteries in our testing pool, so I was unable to determine their actual capacities. I compared the three Li-ion batteries strictly by their run time and charging speeds. That said, Li-ion batteries typically have a larger effective capacity than their NiMH cousins.

In most cases, yes, but where high-performance alkalines generally run at 1.5V (to start with), rechargeables are often designed to run at 1.2V, which can cause problems with a few devices that require a constant high voltage from four or six batteries to operate. However, many rechargeables can run at a higher voltage than their nominal voltage, and then hold on to that voltage for a longer time, even under a high drain. In other words, the best rechargeables actually work better. What does mAh mean? Even though Li-ion batteries hold less of a total electrical charge than NiMH options, they can supply power more consistently and have a higher output voltage. Instead of gradually fading as they drain, devices powered by Li-ion batteries will discharge power consistently and shut off when their output drops below 1.5V. The Eneloop charger is also compatible with AAA batteries, saving you the trouble of buying another charger should you need to invest in the smaller batteries, and thanks to its flip-out power plug, it takes up minimal space when it’s not being used. The fixed plug of the Ladda, for example, means the charger remains 2 inches deep, taking up more space when you put it away in a drawer. Poor results in every testing category made the BUMP AA Rechargeable Batteries the worst-performing Li-ion batteries I tested. Their flashlight and car run times were the lowest of any option, NiMH or Li-ion, and their 180-minute charging times were also the longest. Output was strangely inconsistent compared to every other battery, especially given Li-ion chemistry’s greater expected consistently, and during the toy car test, these batteries would slow to crawl with dimmed lights for an hour or two, then suddenly ramp up to full speed, then drop down to a crawl.

Panasonic Eneloop rechargeable AA and AAA batteries give you the power you need, whenever you need it.

Due to factors like internal battery design, chemical makeup and efficiency, knowing the actual capacity of a battery isn’t enough to give you a complete picture of its energy output under real-world conditions. To evaluate how each battery performed in real-world situations, I used them to power two electronic devices. I timed how long each battery powered a ThruNite Archer 2A V3 flashlight as well as a motorized toy car with flashing lights. This allowed me to compare each battery’s total run time to the others, as well as note any differences in their consistency. I also noted whether any of the batteries came with their own charger and used that to get a better idea of their overall value. The downside of alkaline batteries is that once they’re depleted, they’re useless. That means you’ll have to find a way to dispose of them safely and also spend more money to buy new ones. Alkaline batteries are also significantly less shelf-stable than rechargeable batteries and much more likely to leak. This ruins the battery and typically the device it’s being used in as well. We tested these batteries using a cheap children’s radio-control car (these machines are renowned battery eaters), timing how long each set took to deplete. As expected, there were running time discrepancies between batteries of different miliampere hours (mAh), but all of the batteries featured here performed well.

Welcome to the brand new Panasonic Eneloop AA rechargeable batteries with improvements in performance and sustainabiltiy. These new Panasonic Eneloop rechargeable AA batteries hold even more energy and have an improved capacity of 2000mAh. This new version has up to 7% more capacity and will perform outstandingly well in demanding situations. The Panasonic Eneloop Pro isn’t cheap, but you’re also getting a really nice BQ-CC55 charger, which helps add to the overall value. LEDs above each slot change colors to indicate the current battery level, from red (20% or less) to orange (20% to 80%) to green (80% or more). I find these to be much more helpful than typical chargers that only switch LED colors when the battery is completely charged, letting you immediately differentiate completely dead batteries from nearly full ones, instead of having to wait 10 minutes for it to switch from red to green. Although rechargeable batteries proudly advertise their capacity (generally expressed in mAh), that’s actually a maximum number that it may not deliver. To determine the actual capacity, I used a battery analyzer to charge and discharge each NiMH battery, providing a precise measurement in mAh each cycle. I cycled each one three times and averaged those mAh numbers to compare all the batteries in my testing pool. I also averaged each battery’s charging time during this test. Many customers will have known and used the batteries under the Sanyo brand name. Made in Japan these Panasonic Eneloop Pro AA batteries are the ideal choice for powering high drain devices such as digital cameras, flashguns or photo strobe flash lights. The Panasonic Eneloop Pro AA batteries provide more than twice the number of flashes per recharge in less than half the time when compared to conventional alkaline batteries. Also perfect for wireless keyboards, wireless mice, game controllers, radio controlled toys and a range of everyday electronics. These are the first Lithium rechargeables we’ve tested that we’re happy to recommend. As you might expect, they have plenty of stamina; tested in a 500-lumen torch, they maintained their full 1.51V voltage for just under two hours of continuous use, at which point most NiMH rechargeables we’ve tested are either fading fast or all but dead.The best rechargeables batteries you can buy in 2023 1. Panasonic Eneloop Pro: Best AA rechargeables On a personal note, I used to find it really frustrating that I’d fully charge a set of NiMH batteries for use in a flashgun, only to find they were virtually flat by the time I’d come to use them a few weeks later. Sure, you can recharge them just before use, if you know in advance you’re going to need them on a certain day, but that kind of takes away a lot of the spontaneity and fun from photography. I’ve been using Eneloops for many years and I know they’re always good to go. Indeed, the latest generations can retain as much as 70% of a full charge even after 10 years.
