eneloop pro AAA

Many years ago I wanted to go rechargeable for all my in house devices. I started with the white and black Eneloops. The Eneloops I have back from 2015 still are working in 2022. I've bought more over the years of course too. The black ones can charge 500 or so times, the white ones over 2,000 times. Now, if you charged a battery once a week, it would take 10 years to charge around 500 times. The black ones do have a bit more 'fuel in the tank', and are better for devices like cameras; but overall, the white ones have seemed basically just as good to me for most uses. And they are like half the cost. And they can be charged 4x more. So, decide what you want / need. Both the black and white versions work great. I use the black ones in more 'high demand' devices (flashlights, portable fan, etc.), and the white ones in less demanding devices (like remotes, mice/keyboards, etc.). Haven't had a single issue. I use their 4 port charger (model BQ-CC17). I have two of them that I got with 4 packs of batteries. So, I can easily charge 8 batteries in a few hours. Very easy to keep all my batteries topped up. I have one bin for full batteries, and one for empty; and I just charge them whenever I have time. I haven't bought one time use batteries in about a decade, and I don't plan to ever again. If you are thinking of going rechargeable, these are a great way to start. You get quality that will last, which is the point of going rechargeable in the first place. I have tried many other brands as well, most had issues over time. The Eneloops just keep on going. I will say the Amazon brand batteries have also been great. All have kept working for years and they hold a good long charge and seem good quality as well.

I used this battery 🔋 to my altars look great long lasting!!!

These batteries are on the pricy side but they are hands down the best rechargeable batteries on the market. They are also quick to charge with the right charger. Solid quality too!

As a professional photographer, these are the best rechargeable batteries I’ve ever found. For years I’ve kept multiple sets to rotate in my flashes & gear & have never had to throw a set away. I can’t remember when I bought the first set but it’s been at least 7 years. And I can shoot an entire wedding on one charge.

First of all I'd like to say that I like these batteries. Having recently gotten back into flash photography I've had an explosion in the number of batteries I've needed. Having not purchased any NiMH batteries for about 15 years I did a little research and found that these batteries came highly recommended. Let me begin with a little background on what led my decision. First, these batteries come precharged. This may seem insignificant but it implies two things. First of all they are ready to use out of the packaging: considering even a fast charger takes about 3 hours this is a boon for the impatient. The second implication is that they hold their charge on the shelf well (quoted at 85% capacity after 1 year, 70% capacity after 5 years). Given that my historic experience with NiMH was that they would lose 50% of their charge within about a month this is excellent. This matters a lot for me as I have 4 camera flashes that I use but 2 see far more use than the others but I know that, assuming I left them with some charge, the others will be good to go. The second factor is voltage. When fresh they given about 1.35V and their voltage stays relatively consistent through their discharge cycle down to about 1.2V. This is in contrast to an alkaline which typically starts at about 1.6V but drops rapidly through the discharge cycle until empty. For most purposes the voltage is sufficient (though some older devices may report "low battery") and goes along with the next factor. A typical alkaline's effective capacity decreases proportional to the current draw and provides less consistent voltage. The effective capacity of a NiMH remains relatively stable irrespective of the current draw as does the voltage. This means that for high current draw applications (such as a camera flash) the voltage doesn't dip causing the device to stop functioning temporarily or result in reduced effective life. The ability to deliver high current (low internal resistance) also means that in a device like a camera flash the recycle time is much shorter than with alkalines and doesn't drop as much as the battery discharges. Finally onto capacity. A flash is a spiky, high current drain on a battery which for many cell types is a worst case. I don't have a good point of comparison here, but when I tried some of these on remote triggers at matched power output vs alkalines; these had shown no dip in performance by the time the alkalines were reduced to unusable cycle times. I was also able to use them about the same amount the following day before needing to recharge suggesting that for my use case I get twice the usable life vs an alkaline. Overall these batteries work very nicely. I haven't compared them to the competition but having read some analysis by people who have, my informal assessment that these are high in performance, durability and capacity is echoed.

These last for several days in my solar lights but do not hold charge very long when not in use. I charge them up and a few days later get them out only to find out they need recharging again.

To start off I wanna say that these batteries feel very robust. I feel like I can trust these more than some of the ones I’ve bought before. I know it looks don’t really matter when it comes to AA batteries but wow, these look awesome! These work well with the audio equipment that I’m using them for I use them for wireless gear mainly. They charging any AA charger just like a normal rechargeable battery would. They seem to last for a long time, even working after I forgot to charge him for the next session we used them for on a wireless mic. These provide higher power than normal rechargeable which is why they are perfect for audio equipment.

Envelops are the best batteries you van get. I have envelops that are 7 or 8 years old and still going strong. What can I say?
