Standard Eneloops have a longer shelf life. They only lose 30% of their charge in 10 years, while the PRO batteries lose 15% in 1 year. The following results are interesting none the less. The Powerex 2700Pro is also made in Japan, and is to my understanding the equivalent to the all famous Sanyo 2700 and now called Panasonic 2700 (Evolta). This is the total amount of pops the flash could make on a set of batteries. This is the average between 2 flash units.. according to Sys. The diameter of Pro batteries is larger than regular Eneloops and, therefore, can be a very tight fit in certain devices. So if your standard white Eneloops are a tight fit, don't get the Eneloop Pro.

Another noticeable difference between them is in the recharging capacity. Eneloop Pro rechargeable batteries can be recharged up to 500 times. The very latest 5th Generation of Panasonic Eneloop Pro AA 2500mAh Rechargeable Batteries for professional use are AA size NiMH 1.2V rechargeable batteries. I don't recommend Eneloop PROs for applications with multiple cells that drain the batteries completely . With the focus on draining completely. If you drain all batteries completely, the weakest battery gets hurt the most. Every time this happens, the weakest battery gets weaker and weaker. Eneloop PROs are more fragile and die faster than regular Eneloops. For camera flashes, flashlights, and power-hungry electronic devices, you won’t find a better choice than Eneloop Pro in this price tag.The Eneloop PRO is excellent for Camera flashes, flashlights, etc. When you need maximum power or maximum battery life with a high-drain application, this is the battery to get. Inside camera flashes, Eneloop PRO also recycles the flash faster and can, therefore, pop more bursts in a shorter time! Those who are looking for more battery capacity to power heavy-duty electronic devices must go for Eneloop Pro. Eneloop PRO is excellent for longer battery life in flashlights as well. The capacity of 4 Eneloop Pro AAs is about 25% more than 4 regular AA Eneloops.

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. On the other hand, standard Eneloop batteries can be recharged up to 2100 times making it more convenient for less powerful devices. Shelf Life: The first difference you will notice among them is in their capacity. Where Eneloop batteries come with 1900 mAh, Eneloop Pro has 2500 mAh. Eneloop Pro batteries are not suitable for applications where the battery is continuously charged and used at the same time.

Standard Eneloop batteries have two things that make them stand out over other NiMH batteries: longevity and charge retention. The Eneloop AAA batteries benefits from both. Rated to retain 70% of their charge after 10 years, these are batteries that you can charge up and stow in a cupboard in the knowledge that they’ll be ready for use when you need them. Then came the Eneloop XX batteries. Eneloop XX were first available to the North American and European markets. However, when they finally became available to the Japanese market, Sanyo didn't name them Eneloop XX, but Eneloop PRO.
