Rechargeable AA Batteries 4 Count, Long-lasting Power, All-Purpose Pre-Charged NiMH Double A Battery for Household and Gaming Devices

The batteries charge in a reasonable amount of time and they hold a charge just the same.

they can power my speedlite, it works perfectly, i've been using it for a while, still haven't charged them yet but the performance until now is very satisfactory, it is in fact a good value for the money. PD: a good purchase as a photographer with budget flashes

Duracell has always been my favorite brand of alkaline batteries, & now have become my favorite Nimh rechargeable batteries. I use 3 different brands...& so far I prefer Duracell (sold & delivered by Amazon) over Energizer. To be fair, I haven't used my Eneloop rechargeable batteries yet...so I can't say anything about them...yet. I plan to in the future though. They have a great reputation. Anyway, the Duracell that are copper & green...have been extremely consistent when I charge them on my charger that is not a basic battery charger at all. It tells everything you need to know about a rechargeable battery when charging...& when they are finished charging. It charges 4 batteries at a time. The voltage, maH (capacity), & ma (resistance) are basically identical in every way after charging. That says A LOT to me. They also have a higher maH @ 2,500....compared to Energizer. And so far, none have gone bad on me yet. A couple of my Energizer batteries have lost their usefulness. I can see that there resistance has become way too high to use, so they were retired. To be fair, I've had them for quite awhile now. Anyway, I really like & trust Duracell, a lot. So far.....they've been great. I only use rechargeable nimh batteries now. I really like the idea, of being able to recharge batteries...& use them over and over again. Saves money & not wasteful! I'm not sure if there is any difference, between the ones that are copper & green vs. the ones that are copper & black. Most likely, they just changed the way they look. I like the way the copper & green ones look...lol. I know it doesn't make any difference on how they perform, of course...but they look "cooler" to me. To sum it up, I would definitely recommend Duracell. They are very consistent...& last a long time in my devices. I mainly use AA batteries, so I can't form an opinion on their AAA batteries, yet. I hope this has been helpful.

I love my rechargeable batteries

Hold charge well. Last long time with continuous use

These have a higher charge capacity than most rechargeable batteries. Worth the cost.

Because of both customer and professional reviews, I bought several sets of Eneloop AA rechargeables before finally giving up. My original primary use was for my Canon Speedlight 430EX-III flash for my DSLR camera. The Eneloops (both the high-capacity 2550mAh Black and the regular 2100 mAh White) simply just are unusable effectively with my flash. When I first turn on the flash, it takes several seconds before the flash is ready. Then again after each picture it takes anywhere from 5-15 seconds to recycle so that the flash is ready for another picture. Simply unacceptable. I kept thinking maybe I'd just gotten a bad set because my experience was very different from other reviewers but I have 16 of the regulars and 8 of the high-capacitys and no luck. I tried the Duracells and there is a MASSIVE difference. The flash is ready for use in milliseconds rather than seconds, and between each picture the same. I can take several simultaneous pictures one after another and the flash keeps up - not as fast as the camera but definitely more than 1-2 pictures per second. Since then I have started using them in other devices as well and have seen similar behavior with the Duracells being far more powerful than the Eneloops. I seem to be in the minority on having bad luck with Eneloops but wanted to pass this along in case anyone else has the same experience so they won't keep buying them like I did.

Estas baterías las pedi para el carrito de mi sobrino y son espectaculares las recomiendo mucho si quieres unas baterías recargables q les dure la carga puedes comprarlas, son tal y como las describen
