Excelente pilha cumpre o que promete

Las baterías funcionan perfectamente, tienen bastante calidad y rendimiento. Además me ayudan a generar un mejor funcionamiento en mi Flash para fotografía, ya que al ser recargables brindan al flash una respuesta eficiente.

Very good Batteries. May be a bit expensive to start with but certainly reclaim the cost throughout their life. I use in a large Canon flashgun at weddings. By the end of the day they are still doing a recharge almost instantly. with the best standard batteries I would probably have had to fit a new set. .

The Eneloop Pro AA remains an excellent choice for things like high output flashlights and other demanding devices, but with some caveats. The overall capacity is higher with Pro but it's still important to be aware of the differences before you buy. To start, the biggest trade off with the Pro version is only about 500 charging cycles in its lifespan versus over 2000 with the white Eneloop batteries. However, this is still a fair amount of longevity considering if you charged them twice a week you'd still get about 5 years from them. Next, the self discharge rate is higher with Eneloop Pro. Panasonic states after 1 year a fully charged battery will be depleted to 85% versus 90% with a regular AA Eneloop. Not a huge difference but still worth noting. I've read some reports of the white Eneloops being more forgiving with overcharging and other abuse, but I try to take care of them to avoid problems with performance. Now for the good news, the AA capacity is greater at 2500 mAh opposed to 2000 in the other version. This of course translates into longer run time with devices. For example if you have an item that runs for 60 minutes with a white Eneloop, roughly you could expect a 75 minute run time with an Eneloop Pro or about 20% longer. If this is worth it to you, keeping in mind the shorter lifespan, than the Pro is a good investment. If overall longevity is more important, stick with the white Eneloop. I use my AA Eneloop Pros primarily in some of my flashlights, as I spend a good amount of time camping, volunteering with my son's boy scout troop and other various nighttime activities, so I want as much run time from my lights as I can get and this is an economical way to do so. They don't leak like alkaline batteries and cost much less in the long run, although I do use Energizer Lithium AA from time to time when it's not feasible to pack Eneloops and a charger. From a performance standpoint I've tested many batteries in my 4x AA Fenix flashlight and alkalines are the poorest performers, running for about an 1 hour and 49 minutes on the high setting. The regular white Eneloops last for 2 hours and 33 minutes. Now with the Eneloop Pro I get 3 hours and 24 minutes - almost an hour more. The cream of the crop here in terms of performance is absolutely Energizer Lithium AAs, which run the longest at 4 hours and 42 minutes. The drawback is they are pricey and disposable but still a great choice for when you need stabile batteries, great run times and performance. Regardless, Eneloop Pro are no slouch and have 500 life cycles, respectively. I'd you understand the differences in cells, the Pro is a must for demanding devices. However for average use it's probably best to have both types of Eneloops on hand and save the Pro for your highest drain items.

These Eneloop Pro batteries provide excellent performance and hold their charge well, even after being stored for a while. They're perfect for high-drain devices like cameras, game controllers, and flashlights. The rechargeable design saves money over time, and the overall quality is outstanding. Reliable, long-lasting batteries that I highly recommend.
